I have a magnafuel 500 pump & filter as well as a magnafuel regulator & for some reason the fuel guage pegs over 15 psi & if I turn the pump off then on it goes back to 7.5 normall ?? any suggestions??
I have seen this with there regs. before and had to change out the reg. You may want to call them and ask because I have had to turn the pump pressure down on some of there pumps when they where just to much over kill for the system needs.
