Want to build my own fuel rails

[carfreak85]

Who has built custom fuel rails for their EA81T or EA82T? I need to install a ARRFPR and fuel pressure gauge and it has been suggested that I start from scratch.

 

What parts do I need? Does anyone have a shopping list of the stuff I need?

 

Pictures?

need fuel injctors, fuel rail stock long enough to fit the injectors and manifold, proper injector fittings, fuel injection hoses, hose fittings, pressure regulator, and someone that can do high quality aluminum fabrication and welding.

That would be a nice project with some good gains I think. I have never done it to a ea81t but I have thought very seriously about it. I would suggest looking at some of the vw bug motor mods that some have done while converting the old carb motors over for drag racing with fuel injection. I will post if I find any good places to start from.

subarutex did it on his RX he had.

 

looked awesome, but if i remember he had some problems with it. dont knew if it was the rails or something else though.

Got any leads on the VW stuff? I've been searching the web and haven't found much so far.

Ok, sorry its been so long for me to get back to you Galen. I haven't had a bunch of time...

 

First, my setup was hella $$$ (~$500) and blingy as all getout, but down to actual functionality... i'm not sure it improved anything.

 

I got my fuel rail here: http://www.rossmachineracing.com/dash6.html Looks like they also deal on EBAY. Dash 6 is MORE than enough.

 

I ordered 2' of it, and cut it down to 4 6" pieces. Each piece was then tapped on the ends for fittings (3/8 NPT, probably a $25-30 tap). I then measured the spacing on the bottom to drill and tap for the injectors. These were also 3/8 NPT. Those spots got 3/8 NPT to hose barb fittings (whatever size is needed to fit the hose on the injectors).

 

I then setup my fuel system like a circle. So the rails were connected with a line on one end, then their other ends went to a T which joined them to the FPR.

 

If I had to do it all over again, this is how I would do it.

 

Remove the stock hose on the injectors. Cut 4 equal lengths pieces of hose to replace that which you just removed (probably 12" long or so). Join these with a brass manifold (like a T but with 5 ports, 1 in... 4 out... i've seen them at lowes). Then you just ahve the in on that go to your FPR. Would be cheaper, equal length, and probably better.
