Fuel Tank Vent Question

I've got a 98 SuperHawk that I've been working on as a project bike. Picked it up last year literly in boxes and I finally got it running. Without a forum such as this there's no way I would have been able to find and fix all the little problems I've had along the way.

One problem I had was that the fuel tank was severely rusted. I used Por 15 on it, which looks and works really great. The problem I have is that although I blew out the vent tube with air some sealer must have worked its way back in because it appears to be plugged. The bike runs and will go a mile or two and just quits like its running out of gas. If I pull over, open the gas cap and close it then I can start and run it for a couple of miles again.

My question is does anyone know where inside the tank the vent is? I'm thinking I can scrape off the plugged area and get it working but I can seem to find where it comes out inside the tank. Any help or photos would be great. Thanks

Doug

it's not going to be easy.. the vent is up near the highest point in the tank, a tube that runs all the way up there. Your best bet might be to find some stiff wire and shove it up the vent line to try to break the POR from the inside..

+1 that is what I was thinking, See if you can find some welding rod or something to run through the vent...... though I just replace rusted tanks as once they rust, they are nothing but problems.

So unless it's a tank that can't be replaced, don't even bother with that coating crap, as this is just the first problem, and just replace the tank, it will be so much easier in the long run but as always YMMV.

What lazn said...

I would use a length of bicycle brake and shifter cable to break the log jam. It's flexible enough to snake into curves and bends while stiff enough punch through the obstruction when pushed.

I've just spent the last hour trying to shove safety wire down there.

I'm getting it to the plug but I can't get it to break through. I like the bicycle cable idea, maybe that will be just stiff enough to get through. But it's going to have to wait until tomorrow now.

Thanks for the suggestions.

OK so I couldn't let it go and had to try the cable idea. My original choke cable had broken and been replaced so I cut the old one to length. Connected it to a drill and went to town. It worked!!

Maybe I'll actually be out riding this weekend. After a year of fixing, assembling, buying parts and buying more parts. I actually may be riding this weekend. I'm very excited to take it for a ride.

Thanks for all your help on this and so many other things that I found the answer on here. I couldn't have gotten this far without it.
