BattleSnayke Posted November 24, 2013 Share Posted November 24, 2013 I have 2 questions about the fuel set up in my AE70. I'm doing a motor swap from carb 3AU to 20v 4AGE. What is the easiest/cheapest/best way to do the fuel? Can I just put a high pressure pump into the carb tank or would I be better to just but a new fuel cell, surge tank, lift pump and external? If I was to do the fuel cell etc in the boot, what else would be involved? Would I need to seal the boot off from the rest of the car or is the rear seats enough?

Rookie Posted November 24, 2013 Share Posted November 24, 2013 Aliexpress: 044, surge tank, and a carter ripoff. Buy 2 of the pumps if you are worried about quality. Quote Link to comment Share on other sites More sharing options...
BattleSnayke Posted November 24, 2013 Author Share Posted November 24, 2013 I don't mind forking out for quality parts, it's more whether I can get away with an in tank, or if I need to go pickup, surge and external etc. Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 24, 2013 Share Posted November 24, 2013 You will be pushing shit uphill with a carby tank and an intank pump if you want to do some spirited driving. Â A 4age isn't going to stress any of the fuel parts so I would go with aliexpress stuff. If nothing else the surge tanks are amazing value.

Brock-Lee Posted November 24, 2013 Share Posted November 24, 2013 Have a look in Simon's corona coupe thread. Add baffles to factory tank as well as a bug ass in tank pump. If you got skills/hookups it'll be cheap and quiet. External pumps be noisy as fuck. I think surge tanks look dumb and if I couldn't hide it under the car I'd be doing the add baffles thing. 1 Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 24, 2013 Share Posted November 24, 2013 It is a lot more work though. 044's ain't noise what ya talking about Dayfe.. Quote Link to comment Share on other sites More sharing options...
bobdylan Posted November 24, 2013 Share Posted November 24, 2013 External pumps be noisy as fuck. Â Â May i ask which brands and how noisey? Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 24, 2013 Share Posted November 24, 2013 Like this http://youtu.be/IEp9j73FoZo  And all gerotor fuel pumps are noisey like this, but basically it isn't an issue unless you have a std exhaust. Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 24, 2013 Share Posted November 24, 2013 They get really noisey when the filter is blocked. Quote Link to comment Share on other sites More sharing options...
BattleSnayke Posted November 24, 2013 Author Share Posted November 24, 2013 I'm in no way shape or form capable of such wizardry. So it's really what's available off the shelf/alternative fuel tank options Quote Link to comment Share on other sites More sharing options...
peteretep Posted November 24, 2013 Share Posted November 24, 2013 Im in a similar situation at the moment, I really want to run an in tank setup. all that lift pump surge tank etc stuff will fill my car with trash and extra wires  what is a good in tank pump to run, maybe one I could also buy from aliexpress?

BattleSnayke Posted November 24, 2013 Author Share Posted November 24, 2013 What would happen if I was to run a intank pump on the factory carb tank? What's the difference in pick ups between a lift pump and a high pressure pump etc? Quote Link to comment Share on other sites More sharing options...
peteretep Posted November 24, 2013 Share Posted November 24, 2013 a carb tank being a standard fuel tank which was used on a carbureted car and did not have a pump fitted inside it? Â you can run an intank pump, you just need access to it via a seal-able port of some kind. And it also needs to be in a place where it can be more or less guaranteed fuel all the way until the tank is empty including hooning the car around a race track etc which is why the guys are talking about fitting baffles Quote Link to comment Share on other sites More sharing options...

What's the difference in pick ups between a lift pump and a high pressure pump etc? The fuel sloshes around the tank and away from the pickup / your pump will eat air. On a carb it doesn't matter as the float bowl essentially acts as a surge tank, but on a high pressure EFI system if you lose fuel pressure for a moment you can fuck your engine pretty quick. 1 Quote Link to comment Share on other sites More sharing options...

Had to adjust the lengths of the pipe and mount to suit the shallower tank. Think this is pretty much what simon has done on his Corona?  I would go this way everytime, so nice and quiet and a bunch less wires and hose clamps. Still nothing wrong with going the surge tank route, some OS factory tanks will be a real pain to adapt a in tank to. Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 24, 2013 Share Posted November 24, 2013 And Cars that are EFI stock usually have baffled tanks, carb tanks have no baffles, so when you put an intank pump in them surge is a pretty big issue. Â Like I said, look at aliexpress and see how much bother you have, I know for the price of a lift pump and surge tank I sure as shit won't be cutting up a fuel tank to try and fit baffles and an intank pump.

Spencer Posted November 24, 2013 Share Posted November 24, 2013 Yea got to weld in some baffles to eliminate surge, just don't go around corners with less than 1/4 of a tank. 1 Quote Link to comment Share on other sites More sharing options...

bobdylan Posted November 25, 2013 Share Posted November 25, 2013 I have a spare Twinkie tank if you could make it fit, its yours, no fuel pump and its real dirty but should clean up well. Quote Link to comment Share on other sites More sharing options...
