Low fuel pressure help needed
After setting my fuel pressure to 7 psi it seems to drop off to around 2-1/2 psi. It has gone so low that it actually dropped down to zero, but the truck kept running. When I tried to readjust the pressure up, it wouldn't increase.
I am running a new 383 stroker engine with new mechanical fuel pump and Quick Fuel 780 CFM carb. I ran new 3/8" rubber fuel line from the tank to the fuel pump with an inline filter in between. I also have a filter between the pump and fuel pressure regulator. I'm wondering if it's overkill by having the two filters. Seems like there's a restriction somewhere. Any thoughts or ideas would be appreciated.

Re: Low fuel pressure help needed
Did you use your original gas tank? If so, did you clean it out very good? I'm having a problem with my tank being dirty with a very fine sediment. I could never tell before until i put a see through inline filter. It gets clogged up really fast when i'm driving for a while and have to clean it out. I carry around extra filters for that reason. My regulator and gauge are before the filter so i can't tell if there is a pressure drop but i can definitely feel it in the performance. Will be removing the tank and cleaning it this weekend so i don't have to worry about it anymore.I hope that helps you some.

Re: Low fuel pressure help needed
It is a possibility that the gauge can be faulty, just another sugestion..

Re: Low fuel pressure help needed
rubber fuel lines are a great way to burn your truck to the ground
