Fuel Pump Cleaning or Replace?

Post by 83wingwv »



Hey guys/gals, just a quick question regarding the fuel pump on my 83 gl1100. I took it off my bike to check it out to see if there was any corrosion or what not inside the inter workings of it as I’m overhauling my bike for winter and my tank was recently de rusted and me being dumb, I did not take the tank off or the peatcock when I drained the surface rust that was cleaned from inside the tank. I noticed that the top pump gasket was beginning to disolve slightly and also located underneath the diaphram rubber gasket where the spring sits, I noticed some corrosion but I am not able to remove the diaphram I found out without a drill and trying to refab it to remove it. My question is would you say I should attempt to clean it the best I could as it’s working fine it seems like although I haven’t rented a fuel gauge to determine its pressure, or just order a new OEM pump and gaskets?

Just in case anyone wanted to see the inside of my tank/tank screen inside this is after I just drained it tonight as I’m rebuilding the petcock as well, what do you guys think in terms of how clean it is in the tank/tank screen just from the pics?

That tank indeed looks perfect.

Regarding the pump: if it works fine, why replace it? If the diaphragm is torn, you'll need to replace the whole pump. OEM is quite expensive. I found a new pump on ebay for about €80, which I doubt is original, but it looks and works great.

Thank you for the compliments I tried my best to get that surface rust out of the tank. Thanks for the reasssurance, I just like getting everything taken care of at once when I’m doing work on a bike so I just wanted to clarify that my pump would be okay to continue using

If you are worried about crud being in the pump, just let it pump for a bit on the starter with the hose that normally connects to the carburetors in a jar; if you're worried there is crud in the fuel tap, clean it. Also fit a new fuel filter.

I think you mean the part of the pump below the diaphragm? It is open to the atmosphere, there may be some corrosion but it's not hurting anything.

Rather than replacing a OEM mechanical pump, first consider an electric one. Faster starting is a given as well as great life. But cleaning up your pump is a fine idea as well.
