Stops running. Had 1/4 tank of fuel.was told should keep not less than 1/2 tank for pump to work right. If so could someone tell why? Or should I change the pump?

My experience with a bad fuel pump tells me this...

When the tank is more than 1/2 full it will gravity feed the fuel to the carbs. The pump assists the fuel up but gravity helps. Whe the tank is less than 1/2 full the pump is the primary method of fuel delivery. When the tank is less than 1/2 full the fuel heats up as well due to it's proximity to the hot engine below. The heated fuel then heats the pump and causes it to weaken. Eventually a HOT WEAK pump will not deliver enough fuel to the carbs.

This condition may present itself when at high altitudes also (above 7000 ft). Thinner atmospheric pressure allows the fule to boil at lower temps. Boiling fuel is very difficult to pump.

There is a test in the manual for a weak fuel pump. It involves pumping fuel into a beaker for measuring volume for a specified amount of time. The send part of the test is to pump the fuel to a level ABOVE the tank filler (I think 12" or more) to test pressure as well as volume. A failure of rate will require a new fuel pump. The pump is sold as part of the entire fuel pump assembly and it costs approzx $275 to $300 I think... There are some who have retrofitted a car fuel pump into the assembly and saved some money but I can not direct you to the part numbers.

The mid 90's GL1500's had this problem. Mine is a '96 and I redid the fuel pump 2 years ago at about 90,000 miles....

I also have a '96 GL1500SE and am anticipating replacing my pump this off-season. The link below will provide some interesting reading. I hope it is helpful.

I also modified the electrical current going to pump,used a relay to supply direct power from battery,usin a 4 prom relay,very simple
