GL1000 How to install an electric fuel pump

Post by cfairweather » Fri Oct 20, 2017 4:23 pm



Here is a document that I created when I installed an electric fuel pump on my 1975 GL1000. This is a PDF file and it is stored on my personal web site. Hope it helps someone.

Excellent result - nice write up.

Are the GL1000 pumps no longer available or repairable ?

You can still buy mechanical fuel pumps but there are advantages to having an electric. You can prime the bowls with the electric and my bike generally starts and runs better. I removed the internals of a faulty mechanical pump and mounted it on the bike for looks only. Taking pressure off of the end of camshaft is a good thing. The electric costs about $50.00 and the mechanical costs about $85.00.

Thanks for sharing this Cedric. It really looks clean. As you know, I have the Webers on mine and would like to bypass the old pump all together and get rid of the tach drive too. Can this pump handle full time operation or did you design the system to accompany the factory mech pump?

Excellent job, and great results.

I too, agree with the push button idea.
always wanted to do that with the GL1500 fuel pump, I have always thought it was rediculous to have a situation where the carb bowls could go dry, and then not be able to prime them and get ready for the next start.

goodness gracious, even my chain saw has a primer bulb on it.
and so does nearly every internal combustion engined airplane.

Mike- I find the K&N 81-0400 is the perfect fuel pump for the GL1000. Yes, you can get rid of the mechanical fuel pump with confidence. I ride my 1975 GL1000 down the interstate at 80+mph and it runs great. It also starts right up after sitting in cold weather for weeks. Being able to fill the bowls before you start it really helps this bike. The 81-0400 has a built-in check valve. It also has a regulator to keep the pressure between 1-2 psi which is perfect for the GL1000 carbs. You will have tell us how it works with the Webers.

Good idea if you can get the fuel past the vacuum operated petcock valve too.
I can as I have removed mine and put in a in-line lever operated fuel valve.

I didn't mention that part of my "grand idea" was to replace that vacuum operated valve with an electric one... that way, the primer button will open that also.
