Fuel pump

Postby handyandy62 » Wed Jan 27, 2016 7:52 pm



With the starting problems on my 1977 GL1000, I am thinking about getting an electric fuel pump. What is the flow rate on a stock fuel pump on the GL1000

They do start much faster with the electric pump. Randakk used to have one for sale on his site. It is a low pressure system so not a big pump, 4 psi maximum.

Here is a post about doing it.

Some have reported this one to work well

Confusing. I posted this in your other thread but here it is again. The flow rate is ideal for the gl1000. 2 to 3.5

Make sure it has a auto shutoff.

The electric fuel pump conversion kits and tilt-switch option that we offered previously were discontinued for a variety of business reasons:

1. Supplier / sourcing issues
2. Quality control problems not corrected by the pump manufacturer
3. Pump intolerance of suspended rust particles which is now very common in these old motorcycles. Many customers insist on running with rusty, dirty fuel
4. Unwillingness of customers to follow very specific installation instructions

There is MUCH misinformation published on the internet on this topic. Often neglected: proper engineering of electric fuel pumps for pressure and flow, how to match them to the special requirements of Keihin carbs, how to avoid thermal issues, how to ensure proper electrical supply on vehicles with marginal electrical systems, how to avoid pressure regulation problems, etc. etc.

We may reintroduce an updated version at some point, Meanwhile, we recommend the OEM Honda pump as an appropriate replacement item.

Thanks.

I used use the honda 85 prelude fuel pump and found one at rock auto for under $30.
fabbed a bracket and mounted electric pump where stock pump was mounted.
Many folks have used this pump with success on their 1000 gl.
I also got a stock tip switch from a 1200 wing and wired it in for safety. If bike goes down power is cut to pump.
This setup has worked great for me on my 76 wing.
here is a cartoon of how to hook up pump and tip switch.

Why would an electric pump help starting? There would still be fuel in the carb bowls left from the last time it was run.

There is a post here that you can rebuild the stock GL1000 pump with a Chevy diaphram

or with this material:

(even though I own stock in Honda, I really like the idea of repairing what you have)

This thread is/was originally about the gl1000 carbs running dry (evaporation) after sitting for a couple of weeks or more. Thus having to use the starter to refill the bowls mechanically. The electric pump allows for refilling the bowls without using the starter/battery. This is a common complaint with the gl1000.
