electric fuel pump on wisconsin engine

NHbalerman · Oct 26, 2015

I put a electric fuel pump on my VH4D wisconsin engine and it is a low pressure pump but it floods the carburator,the fuel runs through the settlement bowl but it doesnt
offer enough of resistance to drop the pressure,I have checked carburator and the float and needle valve are working properly with the correct float height etc. Has
anybody ever had this problem and what did you do to fix it. Thanks

Use a fuel pressure regulator. to lower it to 1psi. Jim

"the fuel runs through the settlement bowl but it doesnt

I dunno where your theory on the "settlement bowl" possibly dropping pressure came from, but if your carb is "running over" while being fed from a low pressure (typically 2 to 4 PSI) electric fuel pump, you have carb issues.

The original OEM mechanical fuel pump would have put out at least that much or more pressure and the carb was made to deal with that.

I've had an electric pump on a V465 Wisconsin for several seasons now, and have had no problems. In your case, it sounds like the needle isn't sealing against the seat, thus causing your problem.

Carb issue.

Are you sure there isn't a leak in the float? Hold it up to your ear and shake it to see if there's any gas inside.

How low is the pressure? Shut the juice off to the pump and see if the engine runs better just for a bit. That is one simple way to trouble shoot it. These engines do not require a great deal of volume or pressure. Most were gravity flow. I have a similar problem with my 310G loader. Shut the pump off engine ran as it should plug the pump in started acting up. My pump came off a Deere 55 combine.

Speaking of Wisconsins, where can I get a Manuel for the V465. I need to rebuild one this winter. I have never worked on one before.

I have an electric fuel pump on a VE4 and it
works fine. Never ran better.

Have you noticed if the fuel pump improves the hot starting problems?

Is the screen in the sediment bowl in good shape and sealing around the center hole and outer circumference? If no screen or if damaged I'd say you need an inline filter on it. After you have the filtration issue resolved. Start up the engine with the pump shut off. Run it until it starves for gas then. Turn the pump on. This allows the needle valve to fully open then the flow of gas will flush the crud out that is interfering with the needle and seat reugulating the gas coming in the carb. If you leave the sediment bowl in the line without a screen you will have to make sure the bowl is clean or the flushing process will move the crud out of it into the needle and seat. The flush cycle may need repeated several times.

Thanks. I put it in my favorites.

Just had the same problem on a 465d in a man lift. Had been run on propane for years, switched back to gas. Ran well for a couple days than was pouring gas out of the intake. Tried fuel pressure regulator and bought a new needle/seat. Found one of the floats had a pinhole where it rubbed on the bottom of the float bowl. Dried it out and soldered the hole and has run great since.
