We riding home the other day in 10 degree weather and the fuel pressure gauge decided to put on a show. Running only the pump the pressure will stay at 15psi. If I start the truck the pressure starts out at 15 psi but as the charging systems stops wiggleing the amp gauge and it runs with out cycling the alternator the fuel pressure goes up to 30+and stays there. Performance is good and trust me im glad it went high and not the other way but this is silly.It seemed like maybe something was getting in the line up to the sending unit, ice? So its in a heated shop now and the same condition exists. The wiring is all good and turning the screw into the Holley Regulator shows that its not stuck. The snubber in front ofthe sending unit checks good as well. Is this a sending unit failure?Merry Christmas from the NorthlandKal -
Ok I have been reading posts on fuel temperature effecting the vp44.No one is saying what is a good temperature for the fuel!How hot is to hot?How cold is to cold?If the overflow valve is not allowing fuel to return to the tank then you are stuck with the temperature that is coming from the tank.If the overflow valve is open then the temperature is what is generated under the hood and from friction in the pump and injector pump!So would a inline cooler be a improvement? then if the air is to cold it seems like it would be a detrament and you would want a inline heater.Just some thoughts in my head and I would like to see other peoples thought on this
