Thermoquad worth it - or no?

Rumble is right. I've never seen a badly warped body here in Canada,but usually the body is slightly warped enough to affect seal. I just lay a f;at piece of glass down on my bench top,tape some sandpaper down and then gently rub the body back and forth until it's flat.

Easy,and waaaaaaaay cheaper than a new one.

I've even had some success sealing those well caps rumble mentioned with j.b weld. I figure a better method would be to drill and tap the well bottom and install a pipe plug with jb as the thread sealer. Never tried it,but I think I will next time I find a leaky body.

I test the bodies with diesel,not gas. The diesel microscopically can get through smaller holes than water,so it's a sure bet if you have a leak,diesel will get through.
