351w fuel rail questions..

[ID89GT]

Ok so am still not done with this thing..

I thought I could use the 302 fuel rails. I got new fuel line ran into between them so they would work on the wider intake and all. Well when I went to put the 351 upper plenum on, the fuel pressure regulator is in the way and doesn't work. Sooooo I went to the 351 fuel rails and am now in the problem of finding out how to run the lines to the lines that go to the tank on the car. The 351 has the quick connnects back by the firewall, while the 302 is originally on the passenger side at the front of the engine.

what intake are you using?

I'm doing the same thing and plan on making the lines longer on sn95 rails since theyre bigger than fox rails but don't want to go to a pricey aftermarket setup.

I just have the stock 351 intake that came on the engine

While the stock 351w intakes will get the motor running, they will severly limit power... I hope a upgrade is in the plans?


I used the stock 302 rails, and widened the crossovers with standard high pressure fuel line.

What regulator are you using?
Where is the interference?

I think mine hit the EGR, but that was a long time ago....

Ya I had the 302 fuel rails but when I went to put the 351 upper plenum on, it would hit the fuel pressure regulator..

Ya I have lots of upgrades in the future.. This is just to get the car going for now.

You're using a stock 351 truck plenum?

 

[ls1beater4eva]

why not just buy the upr fuel rail kit its cheap enough and worth the upgrade

 

[ID89GT]

Ya its just the stock fuel pressure regulator.

And ya im guessing its the 351 stock truck plenum, its what came with the engine. My 302 upper wont work

You need to get rid of that truck intake.
