Pulse pump vs electric

KBWOLFE

Is there an advantage to running one over the other?

My experience is these carbs won't tolerate more than a few pounds of pressure so pulse is ideal.

with the pulse, there are less things to go wrong.

I run a 3-5 psi electric low pressure pump on my G2 and have no problems of overflow or leakage. It's easier on the starter/generator because with the electric pump its instant and with the pulse the engine has to turn over to get the system working.
I would read some of the stories of vacuum pump issues and problems - being left along the road out of fuel caused by a vacuum leak. Advantages -- I can go on - I guess it's a personal preference - to me a pulse pump is [the dark ages]. I stepped up into the light - I don't have the time for all the problems I read about here.

I have a electric pump after dealing with a problematic pulse pump setup(which for some odd reasion worked good with the factory engine)
I had to run a return line with mine but I had to even with the pulse pump otherwise it runs great in my club car ds with the vc460

No extra cranking to get the lines primed like Shepard said

My pulse pumps have always started instantly because the carb is full of fuel anyway, and it pumps every time the engine turns over. You have some other problem if it wont start. Pulse is simple and reliable, my old G9 still running the original pulse pump on my clone. If you want electric then get one, I'd rather have efi in my cart but its not very affordable. Carbs are dark ages, even efi is dark ages, should be DI now....imo.

Facet 60304N 1-2 psi. I used this pump on 2 projects. No need for a return line yet.

Really they only problem I've had with pulse pumps is if you run out of fuel or get an air leak in your line, you have to put a lot of fuel in the tank before some of them will prime. If you forget you might be swearing at it because it wont start now that you put fuel in it, when you need to put a lot of fuel in it. Top of tank usually higher sometimes above carb as with most golf carts. Pulse pumps don't like to dry pump up very far, that is why outboards have the bulb to prime them.

One bad issue with elec pumps is if you crash or have a problem they can keep pumping fuel out and not stop, and be a fire hazard. May not be the case with a golfcart but in some vehicles it is. Autos have crash impact switches on them for that reason.

^ some do some don't

I know ford showed where the cut off is on the older explorers in the manual
I think the newer vehicles it's fully automatic

Shouldn't be a problem if the pump's hot wire is connected to the output side of the solinoid for the starter/generator as it would only get power when the engine is running or the pedal is pressed otherwise it won't run

I wonder if the return line is the cause of me losing 6mph on my top end(I have a point of dead throttle after I get 85% on the pedal(which is normally where my 30-36 mph is)
