Goldwing fuel pump

Post by Jag39 »



I recently replaced my weak original fuel pump, with an Airtek pump, I saw in an article on replacing GW pumps. I've got about 3000 miles on it, and it works great, except, the mileage has dropped from 39 to 33 since the pump was installed. I can't think of any thing else that would have made this big change, so wondering if anyone else has experienced this problem. A related question would be, does anyone have any experience with the HFP 360 ST pumps sold for the GW on Amazon? Thinking of switching to see if the same problem persists with a different pump. The only other thing I've considered, is that the breather hose isn't hooked up now, as all these new pumps don't have the fitting. Not sure what the purpose of that was anyway. Perhaps someone out there can speak to any or all of these questions.

Thanks!

If the replacement pump is putting out higher pressure than the OEM pump, it can push more fuel past the needle valves in the float chamber than required, causing more fuel burn in the carbs. You would see a richer mixture because of this - and possibly see the results on your plugs: viewtopic.php?f=7&t=13929

I was afraid of that. Thought I would have a flooding issue though, which I haven't. Guess I will switch it out with the NAPA/Carter pump, and see if that works better. Don't have any idea what any of them are putting out as far as pressure, but found the Carter P72190 on Amazon for $36. so will try that. Still wonder about the High Flow pumps they sell on Amazon specifically for the GW, supposedly. This could end up being a trial and error thing, but will know if the mileage increases fairly quickly. At least I will have a backup pump, or maybe two... Thanks for the reply!

That Carter Fuel pump is the closest aftermarket pump, regarding gpm's and pressure, to the OEM pump I could find. I am pleased with the Carter/Napa fuel pump that I had to replace my OEM pump with. I average 33-35 mph with it. The bike sat for 8-10 yrs and needed the fuel pump so I don't remember what my previous mileage was, but I'm almost positive it was close to the same as what I'm getting now.

on my '98, the OEM pump failed.

I used the P72190 to replace it, AFIK, the mpg did not change for me.

I never considered that. Good option. Thanks!

I'm supposed to have the new pump tomorrow. Guess I will try that first, and see how that changes the mpg. As I said, I was getting 39, and it dropped to 33 with the Airtek pump.
