gas tank problems

#1

Post by george48pan » Mon Nov 09, 2009 3:22 pm

I have a 48 pan with 51 tanks in a 58 or so swing arm. My left tank is starting to weep gas through the bottom near the seat. Is there a 5 gal tank with a through the tank shut off? What year tanks will fit on the frame and clear the pans?

It's a fairly common problem, a crack developing around the rear mount studs. When that happened to my tank, I just had it welded up. The burned paint at the repair didn't show, and a little spray from a foo-foo can protected the raw metal from rust. Same thing happened to a friend while we were out on the road, and he had his welded up at a muffler shop, of all places, and we were back on the road in an hour. (Insert here the usual warning about purging fumes from tank before welding)

Any pan or shovel tanks will fit yer application. Rule of thumb...Shovel tanks will work with shovels, pans, and knucks. Pan tanks will work with pans and knucks. Knuckle tanks only on knucks. All will work with BT flatties....bosheff

To avoid the leak at the rear mounting bolt, I always fit all the mounting bolts loose, tighten up only the rear bolts and then space out the front tabs with washers so the front bolts don't stress the rear ones when they're tightened up. Seems to work o.k.

Is this true about knuck tanks? I have cats-eye tanks on my rigid Pan, no problem. I always thought cats-eyes pre-dated Pans.

I may be mistaken, but any time I ever tried to use knuckle tanks with pans it was a no go....bosheff

Do you rally have cat eye tanks, or just a cat eye dash on pan tanks??

Interesting question. Some one gave me the tanks for free many years ago and I bought the aftermarket cat eye dash set up, which fits perfectly, so I always figured they were cat eye tanks.

How can I tell for sure? (They were really beat up when I got them and took lots of cleaning up, so there are no original emblem mounts. They have the banjo cross over line and a left side tank shift mount.)
