fuel system

[keo92stealth]

hello guys, i was wondering if you could show and tell me how you have your dual feed/ pump fuel system setup?

thanks

I'll try and dig up some more pics of it, but heres the main parts of it at least.

Basically 1 line from the pump to just under the brake booster. Then it splits to two lines over the back of the motor into the driver side end of the rails. Out of the rails into the sides of the regulator, and then out of the bottom of the regulator into the return line.

you can just see the lines coming up over the rear valve cover.


here is both lines coming out to the regulator

ok. i thought that the rails where feed from the passenger side, then on the drivers side, the lines go into the fpr? or does it matter which way you do it?

[Austin@STM]

You can put lines anywhere you want. the regulator goes after the rails are fed to keep a more even pressuer inside them. If the pressuer was regulated before, it would result in less pressure getting to the last injectors, unless you were running a returnless system, but thats not how these cars are set up.

I had a 3SX dual pump/feed kit installed on my 93 VR-4 but sold it to fund another project. I haven't finished building my next setup yet. It's a TGE dual pump hangar with twin Aeromotive pumps, Pampena fuel rails, SX FPR, and black PTFE line. It will be dual -6 AN to single -8 AN through a -8AN fuel filter, then split to dual -6 AN into the fuel rails, dual -6AN into FPR, and stock feed as return.
