Stupid gas tank question of the day

[RobAch]

On an 80 xs400, just got done using HCL on the rusted inside of the fuel tank and then coated with Por 15. Took a few times with the acid but looks good on the inside. Anyway, trying to reinstall the tank. The guides on the frame are min ~1.75in and at very most 2.75in with tank guide flange, while the mounts on the tank are at minimum at least 3in. Is it possible that during the clean out, I somehow deformed the tank? Thoughts would be appreciated.

With the rubber pucks on the tank you should have around 1 3/4" to 2" of gap. Did you cap the tank while cleaning it? I am not sure what HCL is but if it makes any gasses that what cause it.

Thanks. Clearly hydrochloric acid with a capped tank can make major quantities of gas. Quite a few taps with the 8lb persuader and a ratcheting tie down brought things back into alignment.

I've never use Por 15 but if it sets up non-flexible you may have cracked it reshaping tank...............

Great point. Didn’t look too bad but saw one section that might be questionable. Will definitely need to keep an eye on it with gas use in the tank.

btw- any issues it concerns running gas with Stabil in it?

Stabil has less VOC in it than regular fuel, in fact it lowers VOC effects.
