screemin eagle Posted January 1, 2013 Report Share Posted January 1, 2013 While doing an up graded feed and pumps don't forget to make the return bigger too. If you don't the adjustable regulator can't do it's job and you will have massive fuel pressure under boost making the car harder to tune and can also cause massive knock issues. A cheap trick is to use the original feed as the return. Assuming you upgraded your feed. Link to comment Share on other sites More sharing options...
Technology Posted January 20, 2013 Author Report Share Posted January 20, 2013 The feed on the car is -8 aluminum hard line. Stock return. The pressure was fine and since the car is on E85 it takes a lot more fuel. Back pressure is what caused knock in my case, but I sold the car a couple months ago and the new owner had it retuned and was able to get 546 whp out of it. I should have stuck with the stock feed line too. Would have been fine. Link to comment Share on other sites More sharing options...
Laodicea Posted April 9, 2014 Report Share Posted April 9, 2014 You running any e-85 through those hoses? I have been researching heavily and if it is not Teflon or PTFE hose you should not run any alcohol/ethanol throught it. Link to comment Share on other sites More sharing options...

I have been researching heavily and if it is not Teflon or PTFE hose you should not run any alcohol/ethanol throught it.then you shouldnt be running pump has, it has 10-15% ethanol....e85 still has 15% gas in it, which keeps things lubed. ive always used regular hose with no issues Link to comment Share on other sites More sharing options...

kidjc Posted April 14, 2014 Report Share Posted April 14, 2014 Very interesting thread, really enjoyed it! Link to comment Share on other sites More sharing options...
Technology Posted April 14, 2014 Author Report Share Posted April 14, 2014 Thanks kidjc, and to answer the questions, this hose should be just fine, and lots of people found the black goo on their injectors with stock lines. The hose I used was rated for all types of fluid. Link to comment Share on other sites More sharing options...
