Fuelpump rebuild gl1000 (It worked)
Posted: Sat Jul 19, 2008 7:50 pm
Ok here go's I hate things that can't be repaired. I figure if man built it man can fix it so I tried. So far used three differant gasket material's and none worked. I work for a company that manufactures gasket material. None of our stuff would last. Today wife and I were at garage sale and there were two old (not used) mechanical fuelpumps. Got both for 15.00 so heres what I did. Took old wing pump apart.
Ground with Dremel so I could drill used a # 36 drill bit.
After I drilled into pin I took a 6-32 tap and very carefuly taped it out
then with diegrinder ground off top of pin to release top plate and pumper diaphram.
next took fuel pump I got at garage sale and ground slits in side
With a chisel hammerd apart
This was inside
Next ground top of pin on pump off to get diaphram
Put parts on gl pump used a screw and washer to put back together.
need to trim after its all together, Took a wood drill bit and drilled starter holes for screws.
Now trim extra off with sharp blade
. Will put on bike tomorrow. The other ones I did worked for a day or so butt gas ate the material up. Thats why when I saw these pumps I bought them. They should work as they were made to use with gas. Will keep people posted On weather it works and for how long. (will carry my reg pump with me just in case)

I will be watching with great interest!! I am sure that some of the more common car pumps have rebuild kits. We just need someone in the parts buisness to look over a bunch of them and see which would adapt easiest to our application??

Next week i will go to auto parts store. Have a friend that works there and is willing to spend time looking for me. Told him about what I did and he said to come in. He has 2 wings and was real interested. I just hope this works! Have to be careful with tap I broke one the first time I did one.

Installed pump today and it worked great put 50 miles on bike. Not a problem at all. Got home and hooked up pressure gauge in line. It has between 1-1/2 to 2 lbs of pressure. I think this is about right but not sure. Someone can tell me if i'm incorrect. Will keep updated later this week after I ride it more.

The figure in the Honda manual is: 2.4 psi at cranking speed
Volume: 355ml (12 oz) per minute at 600 rpm.

Thanks Octane I was using what Clymer manual stated. Ran at 5000 rpm's. Will check it today at what you stated at cranking speed. Hope you didn't notice mess on my work bench

you wouldn't happen to know what model/manufacturer those pumps were you found at the G-sale?
see, now I cleaned my '79 I noticed the weep hole was dribbling fuel. installed my spare, but now I'd like to rebuild the one that was on.
thanks for your time & effort on it peteybug!

I've emailed this seller on eBay to see what diameter * these *
might/could work... not bad for less than ten bucks. yes, I read his 97% feedback, but everyone who bought one of these has been pleased. and he doesn't take PayPal... risky, I admit.

Heck ya! The real problem is getting good material and you solved that!

Now that you are in the fuel pump rebuild business I recommend a name for your company. Peteybuilt.

Thanks guys. I got a large roll of gasket material from distributor at work. Have some soaking in gas now. Its holding up. If it works out and last I will be glad to share it with anyone who wants to try it. As far as the model of pump i found there are no numbers on them. Thy are prob from a pickup as most cars had smaller ones. Found some rebuild kits for older chevy's and mopars mostly from 60's & 70's and Elderblock (not sure about speeling) makes rebuild kits for there pumps. Still working on where to find.
