Hey guys. Got the civic running, but its running crazy rich and idling at around 3,500rpms. I have a lame ass firewall mount adjustable fpr, and when using the feed line that it came with, it wont hold up to the pressure in the line, and it expands and gets all weak and such. I need to know WHAT psi to run it at, and WHAT hoses I need?


thanks

 

well, what do you have done to the motor, you would need to set the psi according to what fuel pump and how much work you have done, and as far as the hoses go, you may need to get a hose that is incased with a wire mesh.

 

what hose are you using? make sure it is MPI hose not cheese bag low pressure fuel line.

 

its whatever the fpr came with.

its a stockblock z6 turbo with 450's and a walbro 255, crome pro basemapped p28.


should i just say 'fuck the firewall fpr' and get a B&M fuel rail mount so i dont have to worry about the damn lines?

 

thats what i would do. g/l

 

lemme know if you wanna sell the wall mount....wht brand is it?

 

some cheap one from ebay. i figured it would get me by til i can order a aem or b/m, but i guess not

 

get a b&m and if you have problems and not being able to turn down the fuel pressure let me know and i will get you a write up on how to fix this.

 

I don't know that much about crome, but I have been told it is supposed to be alot like hondata. That said, I would check to see if you even need the adjustable fpr. If crome adjusts your injector pulse width like hondata then you need to stick with a 1:1 rising rate fpr....The stock Fpr. The ecu will adjust the pulse width to allow more fuel, so the adjustable fpr is not needed.
