Gas tank question

Post by 754 » Mon Oct 09, 2017 8:35 pm



Good evening all,

A quick question to y'all, I took our '92 1500 out on it's first long trip and it did ok. Still have some small issues to work out. One odd thing I noted was that when I it was time to get gas I would twist the cap off and get a hiss of built up pressure from the tank. I thought they were vented like other tanks? Is the vent clogged or is it supposed to have pressure in it?

Thanks,

Travis

Nope,

sealed system just like your car.

the hiss is normal.

Besides, a little pressure is a good thing. I would only worry if it had a vacuum.

There is a valve in the gas cap but I am pretty sure it is designed to let air in and not out.

It's designed to do both. It lets air pressure out when it gets hot and expands, and it lets air in to replace gas that is being used up.

always put the cap on so that you can read the word GAS... most people know this but perhaps newbees don't ;)

Ya know, never thought of that. I always just screwed the cap back on and had the hose point in the same direction it always had....no issues. The little things manufactures think of ;)

Why is that? Is there an issue with having it any other way? It has never been a problem for the three GL1500's I've had.

What type of malfunction or odd behavior would be noticed if the fuel cap was installed with the word GAS inverted?

Shift into reverse will fix that! :mrgreen:
They say 98% of all Hardleys ever made are still on the road..... The other 2% made it home. :lol:

If my bike wasn't an Interstate I'd happily shift into reverse if that would help with getting it to run without a surge. :mrgreen: Got a TW sensor to put in today and then some reassembly and hopefully after that it'll be running like it should.
