Tank leak, tap/petcocks

There was a gas tank leak from the RH side. It turned out to be a pinhole, presumably from internal rusting. Fiberglass was chipped out to reveal previous repairs.

 Pinhole in center of white marker pen. It was very small so I dented it in slightly in prep for soldering.

Gasoline was washed out with hot soapy water till suds remain. Then it's safe to solder with a lpg/propane torch. I used regular solder with hydrochloric acid flux. The secret is to get the work clean before attempting to apply solder.

 Solder over the pin hole.

 The RH fuel tap/petcock. It's sealed at the thread with Loctite 567 Teflon paste.
