I will have an application coming up that will require a fuel pump as the tank will be below the carb.
The carb I have is a new Ultima R2, S&S Super E clone. This will be in my Harley powered MG M-Type replica car. The tank will be behind the seats and below the carb up front of the car.
I've read that motorcycle carbs do not like high psi. I was thinking of a fuel pump in the 2-4psi range, but just wanted to ask the question. I know that sometime someone here has had to run a fuel pump.
Any help would be greatly appreciated, Thanks!

I'm more of an automotive tech but we used to run 3 to 5 pounds on them. I would think the 2-4 that you are looking at would be fine. Volume is generally more important than pressure on a carb.

I don't think I'll use nearly as much gas as the 1.5 to 4 psi pumps put out, 20 to 28 gph. I just don't want to overpower the needle/seat and flood all the time. Most motorcycle carbs are used with gravity feed on the gas, so basically maybe 1 psi?
Thanks again and I'll keep you all informed on my project.
Have a great week!!!
