1985 GL1200A Limited Fuel Pump

Post by rubiron05 »



Sorry to bring this topic up again. I searched the forums but could not find what I was looking for. The bike was my father-in-laws who has since passed away. The bike sat for a couple (maybe more years) and has 22k miles. I have gone through and cleaned all the varnish I could from the system. The last piece that I tested was the fuel pump which has been deemed bad. The part number for the LTD I was given is 16700-MG9-952, which I can't find anywhere. I would like to use an OEM replacement if at all possible.

My questions are:
1) Does anyone have a working (used) fuel pump for sale?
2) Is there a way to refurbish the pump I have? I know there is probably varnish that needs to be cleaned but not sure if I can soak the pump in some mineral spirits or ??

I would really appreciate any advice/help....

My personal idea.
If the pump is bad,you can't make it worse by trying to restore it.
I'd first soak it with a plastic safe mix including 50%ATF for a few hours.
Apply power and tap the case a few times to "wake it up".Should it spin over,let it pump that mixture a little while and let it rest a day.
Rinse and repeat till it fires off Everytime.
If you know the specs (pressure and volume) you may be able to "Google" for a replacement pump.Pressure is the most important thing for a carb engine.Pressure needs to be accurate on a Fuel injected bike.Volume can be a bit higher but not lower.

I've replaced mine. Use a Spectra SP1186. Specs: Free Flow Rate: 46 gph/174 lph - Maximum Pressure (psi): 118 psi.

Check out a local wrecker as well for a fuel pump off an older Honda, Subaru and such. Seems all these used similar pumps.

Thanks for the advice, what would you mix with the ATF that is plastic safe but could possibly remove varnish?

Could you elaborate on what modifications you had to do on this fuel pump? If I remember, the high pressure side is expecting the fuel out the side of the nipple that then goes into the collar (forgive me if I'm not using the right terminology. Also, it is rated at 118 psi and the bike requires 90 psi from what I have read. Did you have to incorporate a pressure regulator as well or does the bike just use what it needs to pass the fuel.

Thanks.

My first "go to" chemical is simple alcohol.
It thins the ATF so it can soak in.Another choice is PB Blaster.

The bike requires a static fuel pressure - key on engine stopped of 36 psi, and an operating pressure at idle of 28 to 34 psi. The existing OEM fuel pressure regulator takes care of this.

I shortened the inlet about a 1/2 inch to accommodate the fuel hose. The outlet fuel connection fits this fuel pump. You will have to add some rubber around the new pump to hold it securely in the OEM bracket.
