Honda GL1500 GoldWing Fuel Pump Replacement

This article describes replacing a stock fuel pump with an unapproved aftermarket replacement. If you attempt this procedure, you do so at your own risk. You will be dealing with electricity and flammable liquids. Explosion, burns and death are possible outcomes of attempting this procedure. You are fully responsible for all results. OK, now that we have that out of the way . . . Has your GL1500 died under conditions of hot ambient temperatures and high load and then mysteriously restarted and ran fine after it cooled down? You may be experiencing a weak fuel pump.
On one trip, I had my 1500 repeatedly stumble, lose power and die under such circumstances. I was pulling a mountain pass, 2-up at 70MPH on a 95 degree day. 3 times I had to pull over, checked what I could and after about 10 minutes of poking around it restarted and ran fine for several miles only to die again. The last time it didn't completely die and I stumbled into a gas station at the top of the pass. I refilled the tank, let it sit for a few minutes and it started and ran fine the rest of the way home.
After MUCH Internet searching and forum message exchanges, I narrowed the most likely culprit down to "weak fuel pump". There are other issues which could cause similar symptoms and should be examined first, like a clogged fuel filter, gas cap not properly venting or even flakey fuses. I checked and eliminated these and all other causes I could think of and was left with the weak pump syndrome. The information I gathered from several sources on the Internet indicate that GL1500s built in 1994, 1995 & 1996 are most susceptible to this problem. It seems that some pumps, when they get good and hot, either totally quit or just can't generate enough pressure and flow to get any fuel to the carbs. My Wing is '95 model so it is not surprising that I have the problem.
