electric fuel pump m18???
 

I want to put an electric fuel pump on my M18, what pressure and flow rate should I be looking for? This is on a project tractor so I don't have a model # for you. The gas tank is almost a gravity feed since it is above the engine, not back under the seat pan, so I wouldn't be pumping it far.

#5-7 maybe 20 gpm's about $30 on ebay,-- search 12V fuel pump.
I use a small square one on my little onan generator for years.

I read somewhere to make sure the new electric pump doesn't put out more than 2 1/2 lbs of pressure. Didn't see anything about a flow rate. Anyone have photos of your electric pump installation on an 1811 or 1872? I'd like to see them.

I found two pumps, one puts out 1.5 - 4psi and the other puts out 3-4psi. Why would the psi vary, or can they be set? They are solid state pumps, Facet brand.

If it's above the carb you don't need a pump.

If I didn't need a pump I wouldn't be asking for help to find the right one.

When I am low on fuel the engine surges but when I fill it full it runs great. I don't think it is enough pressure. So back to my question, which fuel pump would work for the m18? Either one?

Oak, I talked to Duke the other day and he said you had put one on one of your tractors but he didn't know which one. What did you use and what was it on?

Chip, I didn't put one on my 1811 because it wasn't needed. I didn't know you were having issues on yours, sorry I can't help.

According to Kohler, their Fuel Pumps run in the range of 1.5 to 3.0 PSIG with 3 PSIG being the Maximum.

Thanks! I looked at the Kohler service manual and online and couldn't find that info.
