afpr needed?

[supraian]

i'm gonna be running around 14-16 psi my current fuel system is lex afm, 550's, 255 walbro pump and 12v mod. will the stock fpr be able to hold the pressure from the walbro or should i get an aftermarket afpr?

Stock fpr should work just fine make sure you drill out yor j-tube

Any pros and cons on drilling the J-tube on a Stock fuel system??

thx

There isn't anything to be gained by it, you'll only lose a fail safe incase your FPR does fail.

 

[marlonvip]

so I need a afpr so that I can regulate the fp my self??

What MKIIIman was talking about is.. If you drill out the J-tube and you have a problem with the stock FPR you run a risk of low fuel pressure. That little pinhole in the J-Tube acts as a failsafe to provide higher fuel pressure.

Hope that helps..

The AFPR isn't NEEDED, but it sure would be something to good to have so you can lower you fuel pressure when you discover you're running pig rich and need to do something about it .

AFPR, drilled or remove j-tube, and 12v mod are not needed for your mod level. However the first 2 are definitely good insurance.
