Set the scene: 18 hp Briggs & Stratton opposed twin with vacuum fuel pump. I want to change out for electric fuel pump. I know I need a low pressure pump, a filter, and preferably a check valve. Help me, what do I want??

Had to do that casey! :smilewink: A Mr Gasket model 42S fuel pump, or THIS ONE or THIS ONE or any pump putting out less than 5psi. Put any decent fuel filter between the pump & the fuel tank. These pumps will be ruined by any crud. Place the pump as low as possible in relation to the tank's bottom as these pumps push much better than they pull. You casn mount them high, but if you run out of fuel, they sometimes have trouble picking the fuel back up. You won't need a check valve.

Thanks Dan, and I plan to mount it on the chassis below the tank where I had just relocated the old vacuum pump which ironically, doesn't want to work, so I already have mounting holes lol. I will check out those links here. I do have a question, what about float needle, will these pumps try to push on those constantly?? Or is it just ok. I know I had rebuilt my carb with neoprene float needle.

The 42S is a spinning pump much like automotive fuel pumps.  I've had one in my Massey with FEL for a few years now & not the 1st problem.  The others are pulse types, with a reciprocating piston going back & forth with the fuel passing through it's center, with a check valve in the piston.  All work good.

With a good float & needle/seat, a low pressure pump won't overpower them.  I had to put a pressure regulator on my Wisconsin TJD because their floats are kinda small & can be overpowered.

I see those pulse pumps are available in all types of low pressure ranges and rated gallons per hour, what is the benefit, what range should I be looking at with them?

The lower the better in our applications.  GT's take little volume or pressure.  1.5psi is plenty, and up to 4psi or so is usually fine.

So 1.5 to 3 psi at 15-20 gph would be a good choice?

I've been using the Mr. Gasket diesel pumps in diesel conversion and they have worked flawlessly. Think I purchased them at

O'Reilly  auto parts.

I converted my GTX-18 to an electric Ebay special pump about 2 years ago.  No troubles with it at all.  Since it's wired on the "ignition" circuit I can run it a few seconds before cranking the tractor to ensure the bowl is full.  This helped the tractor start right up when I woke it from it's winter hibernation this year.

That is the best part.  How many times when a tractor sits with a vacuum fuel pump that you have to grind Z& grind the starter before enough gas gets in the carb bowl to fire!  Not good on the starter or battery.   Certainly not good for us as the batter will go dead JUST as it tries to fire! :wallbanging:    Never again with electric!
