Abarth Posted March 14, 2017 Share Posted March 14, 2017 Hey Looking at getting a new fuel rail for a Fiat Punto GT. Been searching on the interwebs and there are a couple round Europe but they are steep at 199 Euros each. I was wondering if anyone has had one custom made locally in NZ?

toy-mota Posted March 14, 2017 Share Posted March 14, 2017 Im unsure of your setup.but i made a custom fuel rail for my 2jzge.i got a 2foot length of alloy fuel rail extrusion off ebay.the main hole is the right size for a an10 thread and i just drilled my own injector holes. I think it was about $90nz for the fuel rail including shipping Quote Link to comment Share on other sites More sharing options...
Abarth Posted March 14, 2017 Author Share Posted March 14, 2017 Might give that a go, the factory rail runs this fuel pressure reg on the end which as been replace by a Malpassi one like in the yellow car. Aiming to follow a similar setup as the yellow car in the photo. Did you tap a helicoil in to the AN10 thread? Quote Link to comment Share on other sites More sharing options...
Rookie Posted March 14, 2017 Share Posted March 14, 2017 I do this reasonably often at work, you just tap it with a 7/16-14 thread (which is an10) straight into the alloy and use a 10mm hole to pilot the injector holes for a 13.5mm pin guide end mill ( not all the way through of course) to make sure you get a nice surface finish for the injector orings to seal on. 4 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted March 15, 2017 Share Posted March 15, 2017 Hi rookie. What is a pin guide endmill? Do you use it in a hand held drill or drillpress? Quote Link to comment Share on other sites More sharing options...
Rookie Posted March 15, 2017 Share Posted March 15, 2017 Hey man, it is just an end mill with the tip ground down to a pin so there is no flutes there and it acts as a guide, you buy them,they aren't cheap, but they are the right tool for the job, the one you want in this case is a 10mm pin and 13.5mm cutting diameter. Order of ops is Pilot hole of your preferred size 10mm hole all the way through 13.5 mm end mill down to say 1/2 depth Deburr and chamfer both outside and inside. I do it all in the drill press so I can use the depth stop for the endmill, (the last set I did were for a v10, so having all the holes at the same depth made it easier for mounting the injectors) and use a digital angle finder to set it up level in both directions, but if you were careful I don't see why you couldn't do it all with a cordless hand drill. 2 Quote Link to comment Share on other sites More sharing options...

Don't wanna be an egg but you sure AN10 is 7/16" Mr rookie? Think it mightve been a typo. I normally make it 7/8" when I machine that fitting size. Good catch bro, it is indeed 7/8"-14 1 Quote Link to comment Share on other sites More sharing options...
