John Deere LX 178 Kawasaki FD440v engine

My fuel pump bit the dust and they are $130. I'd like to consider putting in a small engine electic fuel pump. Does anyone have a comment/advice/experience.
The engine is a 15 hp twinn water cooled and I do not know the flow rate or pressure. Maybe some wone could help with that too?

Sure, I have the LX188 which is the same mower and engine, just with a hydro tranny. My pump went out too, and I put an electric pump from O'reillys auto parts on it. They had one made by mr. gasket for $35 but it was made in china, so I asked for alternatives and they brought me one made in the USA and it was less $$ too. Just be sure to get one made for carbureted vehicles (low pressure). I mounted it to the frame on the left side of the mower next to the engine and spliced off the fuel shutoff solenoid wire under the carb for supply power so that the pump would come on when the key was turned on.

Help needed with John Deere LX178 Kawasaki fuel pump

Hello!

We have a John Deere LX178 15 HP lawn mower. We found out today it has a Kawasaki engine.

My husband thinks the fuel pump has gone bad and we priced a new fuel pump at our local John Deere service center for $140.

Does anyone know where we could find a fuel pump at a cheaper price?

Any help would be greatly appreciated!!!

Thank you cheese!
What part do I ask for at Reilly's? I looked online but couldn't find the fuel pump. So the fuel pump will run off the battery instead of the engine right? Thanks so much for helping me!

Right, it is electric. Ask for an inline low pressure electric fuel pump for carbureted vehicles. It's a generic inline fuel pump. Around $30 I think.

Mine just failed this weekend. After replacing with an electric, what do you do with the mechanical pump? Do you leave it connected to the engine block? Should I plug the fuel ports or leave them open? Thanks

Just leave it there. It doesn't matter what you do to the ports.

I am having the same problem with my LX178. It is dumping fuel out the side the of the fuel pump, directly on to the exhaust. So I guess I have a couple questions.

Do you think my fuel pump has quit working properly? or do I need to have my carb adjusted?

Next. I plan on purchasing the fuel pump from o'reillys, because I can not afford $130 for a new JD fuel pump. Which wire do I splice into on the bottom of the carb to make the pump come on with the key?
