I am replacing the electric fuel pump in my 1959 Beuhler Turbocraft Jet Boat and was wondering what size of pump I needed to replace it with. I put a small one on it already that puts out 7psi and it can't keep up. |

5 to 7 psi is what i would recomend.Are you sure you have no restriction or leak in the supply line.If you go to a higher psi you risk the needle valve not holding and flooding the engine.You might need a higher volume pump. |

The problem is not the pressure but the volume of the pump. Calculate how much fuel you use at full throttle, add 25% and that should be the rated flow. |
