Fuel pump weeping gas,grease

Postby wingerinsandiego » Sun Jan 05, 2014 4:54 pm



Hi all! First of all thanks to Cyborg I finally got to the fan switch shorted it out and the fan ran fine. After letting her idle for about 15 minutes the fan kicked on just past mid range. What a relief to see that thing operating properly. While at idle I noticeon gas coming from the fuel pump area. upon closer inspection gas and grease was coming out of the weep hole. I know these pumps are not repairable and I found a new one on flea bay for $88. Mother Honda wanted $109. My question is can I convert this to an electric pump? If so how would it be done? Any advantages or am I better off ordering the new mechanical one.

Relatively easily. You require a GL1200 pump, mounting bracket and a relay wired into the ignition circuit so that it only runs when the circuit is live. This is one mounted on my own bike.

Hmm, well, I will try later but although I can do wiring, drawing diagrams isn't my strong point either. :(
But it is simple enough. You need a standard auto relay with mounting bracket. I took a direct lead from the battery + to the relay and obviously a lead to the pump from the opposite terminal. The actuating current is taken from a coil lead, so that the pump can only rum when the ignition is on. The only problem with this is that the pump will run as long as the ignition is on.If you have an 'off' , even if the engine dies the pump will keep pumping until the key or the cut-out switch is off.

The wiring on my bike is not standard, as you can see.

It's an oil pressure sender unit. The 'tank' top fuel gauge has been converted to an oil pressure gauge. I have the fuel gauge in the GL1100 idiot light cluster fitted.

Wow you two are something else. Thanks for all the pictures and explanations. I kept the old 1200 pump from my 85 LTD. I think I will start with that since it was working when I swapped it out. Will let you know how it works out. Excited to get started. There has to be a way to put a cutoff switch or relay in line to turn it off. I live for this kind of stuff. What a great site and fantastic people.

The pumps are made by Mitsubishi and used on many different models, the only difference between them being the outlets. The pump on mine is off a Kawasaki 600 carbed model.

Keep it simple if you are not very experienced with electrics as others are-Buy anew standard mechanical pump and fit it-end of storey
