We just started my new turbo motor last weekend and we are having fuel pressure issues. We flared the stock line into a -6 into an earl's in-line, then up to an Aeromotive A1000 fpr. The gauge is a matching aeromotive showing 15 psi of fuel, then we switched to a blox gauge and it showed the same. Pump is a walbro 255lph. Not quite sure what is going on. Any suggestions would be greatly helpful. Thank in advance

 

Do you have an internal leak at the fuel pump? A hose popped off, loose clamp, etc.. at the pump exit/outlet can do that.

Are you also experienced with fuel systems in general? Many cases, I have seen folks accidentally hooking up the regulator at the wrong ports, and in turn, it gives some totally wacked up fuel pressure readings.

 

i havent found any leaks anywhere. Not a lot but i have some. I have the feed on the right port, to the rail on the left port and the return coming off the other side of the rail. even when my tuner starting messing with the adjustment on top of the fpr, it didnt move

 

Crimp the return line if the pressure goes up it's the regulator. If it doesn't your issue is the hose on the walbro is leaking or broken or popped off. I had then same issue last week with my dual walbro setup and my issue was a leaky hose. It had a gash in it and my fuel pressure gauge said 10psi

 

i will try that next time i go to the car
