Fuel Pressure dropping to 51 psi? I have a walbro 255 intake pump, no hot wire kit. Recently my car has gone from a normal 12.9 afr to about 13.4. I noticed my fuel pressure is at 60 psi at idle and cruising but under wot throttle drops to 51 psi on my autometer gauge. DO you think the pump is going bad or do I need a hotwire kit? Thanks.
