I run a Wallbro 255 and an Aeromotive A1006 regulator on my return style fuel system. I have an electric FP gauge in the and its bouncing around a little - about 3 lbs +/-. This morning I went to start the car and my FP wouldn't gp above 35lbs.

I'm trying to figured out whether it's the FP or the regualtor that may be causing the problem.

Thanks,

Kevin

 

I'd be looking at the pump first...

 

+1. Pump first, given recent postings about the Walbro failure rate.

 

I would check with a mechanical gauge first....
