Josh Posted October 14, 2007 Share Posted October 14, 2007 Just wondering what the best way to mount my fuel pump is, I'm going to mount it under the diff arch but am wondering the best way to mount it to the body. Heres what the fuel pump looks like: I was thinking just making like a strap thing out of some alloy I have lying round that goes over it and bolts to the body, would this be the best way, any other ideas that could be better? Don't want it falling out.. Also it doesn't say which way the fuel pump goes ie, which way is in and which is out, I'm assuming the threaded side would be the out since it has the pressure? Someone to confirm/tell me I'm wrong would be great. Now another thing is I'm running 5/16" lines I think they are (8mm more or less) and the fuel pump inlets/outlets are 10 and 12mm, so the hose wont fit over them obviously, I'm a bit stuck on the best way to somehow join the 8mm onto the larger fuel pump outlets in the best and most basic ways, hopefully someone has some ideas for that because mine seem to complicated. Next thing is the fuel lines run down the right side of the underside down the drive shaft/gearbox tunnel, at one point near the gearbox they have to run over the top of the exhaust, would heat wrapping this section of the exhaust be enough? Don't want it melting through the fuel lines!! Its probably less than 100mm away from the exhaust at this one point it has to cross over.

lowlancer Posted October 15, 2007 Share Posted October 15, 2007 Can buy VL/Bosch style pump straps/mounts Get bigger fuel line between surge tank and the pump, and outlet of pump and fuel filter to overcome size issues As for the fuel lines, assuming they are copper/steel? Heat wrap should be okay, but see what else you can do Quote Link to comment Share on other sites More sharing options...
Josh Posted October 15, 2007 Author Share Posted October 15, 2007 No they are efi rated rubber hoses. Dont have surge tank, need somehow to convert the pipe up to the bigger size on fuel pump. All good will sort it somehow. Quote Link to comment Share on other sites More sharing options...
lowlancer Posted October 15, 2007 Share Posted October 15, 2007 Aye? So you're running efi rubber hoses all the way under the body? Fuck that stz if so Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted October 15, 2007 Share Posted October 15, 2007 heaps of euroshit ha same pump, with rubber mount and strap type arrangement. think bmws and some peugeots Quote Link to comment Share on other sites More sharing options...
Ke36 Posted October 15, 2007 Share Posted October 15, 2007 ok here goes a life story i got a polished/anodised which is paded for mine was like 50 bucks form nz performance, i assume you want something decent for it as the rest of the car is top notch standard http://www.trademe.co.nz/Trade-Me-Motor ... 725102.htm for the pump, yea threaded part is outlet yuo can take that off as the place i got my fittings for couldnt get a banjo fitting etc to fit on that outlet, they say 95% of people they get through just biff them and dont worry bout it (cylinder head speacialists here in chch so they know their shit) i had an absolute cunt getting my fuel setup done as apparently they dont make any speedflow pushlock or braided fuel fittings in 5/16 as its not a size you see in yank land easest way to do it if you want to run original 5/16 fuel lines is get a adapter out of the pump to fit a speed flow fitting then fit a -6 size then get a metric hose tail 10mm to 8mm adapter so you can run from the pump onto your original fuel lines i farked around putting flare nuts on my fuel lines then a -5 to -6 adapter etc so im running all dash 6 stuff but steel lines are still 5/16 ended up costing my about 600 in adapters fittings and fuel line but wanted it to look tidy and not have more breaks in my line than i needed design your setup with as many straight fittings as possible there about 15 bucks as soon as you put a bend in it they get up towards 50 bucks i used a simple repco efi filter (car isnt here at the mo will edit post with part number when im near it) for my two filters (pre and post pump) as theyve got metric threaded fittings in them and big inlets/oulets (like 3/8 or 1/2) and are only like 20 bucks each rather than $200 that a sx filter etc is heres a pic as i was keen to see other peoples setup to get ideas for mine but couldnt find many so anything that might help edit: after you guys all posted while i was writing marathon your stupid to not run a surge tank with all that setup, and you need a lift pump as the bosch ones do not like sucking fuel at all Quote Link to comment Share on other sites More sharing options...
lowlancer Posted October 15, 2007 Share Posted October 15, 2007 damn, spendy^ Here's a pic of mine incomplete. Not show standard by any means but worked mean. I avoided fittings like the plague due to cost, but they do look a lot better than what I was rocking Please note I did have grommets for haggard holes Quote Link to comment Share on other sites More sharing options...
Josh Posted October 15, 2007 Author Share Posted October 15, 2007 Cheers, valuable info there, I'm not really after a "bling fuel setup" so to speak, as none of it will even be able to be seen anyway/I dont care I just want it to run Running a fuel filter much like the one you have there lowlancer, skyline type one?

Gaz Posted October 15, 2007 Share Posted October 15, 2007 Hey yo. Run 10mm line. Your not allowed to cross fuel over/under exhaust I dont think.. Bring to engine bay then cross over near firewall. Underbody fuel pumps need a sheild fitted. Threaded side is out. Hope that helps Quote Link to comment Share on other sites More sharing options...
isnowi Posted October 15, 2007 Share Posted October 15, 2007 note that although they are very nice and make for a tidy job, there is no reason why brass hosetails can't be utilised instead. I have an almost identical setup to KE36 (sorry dude can't remember your reel name.. ) only my setup uses brass hosetails and efi spec hose clamps (stainless jobbies with a complete rolled edge so they dopn't cut into the hose) Also think that a surge tank and low pressure lift pump will be of great benefit, high pressure fuel injection pumps need a head of fuel above them in order to keep them lubed, and they suck ( no pun intended) at sucking. Pics and specs of my set up: there is a fuel filter before the low pressure pump, but it is outside the car in the body recess above the fuel tank. Shot with DYNAX 5D at 2006-09-15 the low pressure pump is a carter off of TM, surge tank off TM, about 3M of high pressure hose and stock hardlines up to the front of the car (3/8" bundy tube, being that the flex lines are only 10mm i didn't see a problem using them) BTW an old coil bracket and a couple of cotton reel mounts makes a pretty reasonable pump bracket.

eke_zetec_RWD Posted October 15, 2007 Share Posted October 15, 2007 it looks like the tail out of the pump screws out, if so put the correct size fitting in it for your pipe..... Quote Link to comment Share on other sites More sharing options...
Josh Posted October 15, 2007 Author Share Posted October 15, 2007 Methodz: I've already got the 5/16" line now so may as well use it. I think I'm going to run fuel tank>filter>pump>fuel rail>return back to tank. RT ran this setup as far as I know on his capri and had no problems with it as far as I know. Cheers for the pics of your setups to. Quote Link to comment Share on other sites More sharing options...
kyteler Posted October 15, 2007 Share Posted October 15, 2007 Will it be used in anger? Because if so I would seriously suggest a surge tank, the last thing you want is for it to starve itself of fuel, lean out and POP, all your time and money spent on the turbo setup down the drain.

Josh Posted October 15, 2007 Author Share Posted October 15, 2007 Hmm, I don't want to thrash its arse off but do want to use it to its potential. Haven't skimped anywhere else so I guess it would be stupid to do so now. Quote Link to comment Share on other sites More sharing options...
RT Posted October 16, 2007 Share Posted October 16, 2007 so many opinons lol. luv it. Josh as long as you've got at least 1/3 a tank of fuel you won't surge, when you're down to your last 1/4 just don't thrash the tits off it. Imo you only need a surge tank if it's a racecar. when I only had 1/4 of a tank and lauched it in a straight line it would surge even with the droptank cos all the fuel would fly to the back of the tank. Took me ages to work out that was why it backfired sometimes. But yeah, it's not like you don't like spending money. So get a surge tank, polish it up all bling and mount it in teh boot. Run a low pressure filler pump off something to keep the surge tank fill. Then run the bosh inline in your boot from the surgetank, through the boot floor and up one side of your car. Yes you can cross over the exhaust if you had to. I did and I got a cert. I kept it as far away as poss. Wrapped that section of exhaust and also wrapped that section of fuel line in fire proof heat shield stuff. I mounted mine in the arch right beside my droptank, I pushed the pump into a sleave of rubber (truck radiator hose) and made up a bracket out of big hose clamps. But it's quite noisy. You can buy the correct mounts off trademe. Quote Link to comment Share on other sites More sharing options...
Gaz Posted October 16, 2007 Share Posted October 16, 2007 ^^ yuh all it takes one corner s bend on full gas with little in the tank to go bang. Quote Link to comment Share on other sites More sharing options...
kyteler Posted October 16, 2007 Share Posted October 16, 2007 I don't think of a surge tank as any kind of bling, just as a engine safety precaution, the costs of plumbing one in vs. a "what if" moment makes it worth it, IMO Quote Link to comment Share on other sites More sharing options...
RT Posted October 16, 2007 Share Posted October 16, 2007 it doesn't go bang. It makes a small pop. Surging doesn't blow up your engine boes. Of course, it's still super gay and annoying. Quote Link to comment Share on other sites More sharing options...
Josh Posted October 16, 2007 Author Share Posted October 16, 2007 I see. I don't like spending money the way you put it either! Hence why I've done as much as I possibly can on this build. I had the o.e hole welded up in my fuel tank, and a outlet welded into the bottom on the tank, then a return welded into the top of the tank. I suppose this is useless now if I ran a surge tank as the surge tank would have taken care of this? Also the surge tanks I see on trademe have 4 outlets, id assume, inlet, outlet, breather? Whats the other one? Quote Link to comment Share on other sites More sharing options...
