gas tank filler

Mike(NEOhio) · Nov 17, 2016

I want to replace the old vented filler on my farm tank with a pressure cap. Put Kroil on it and gave it some raps with a hammer. I'll try again tomorrow with a bigger pipe wrench. Any suggestions on how to get the old one off?

I keep a couple pieces of 2" EMT around for cheater pipe. About six foot should do it.

That would have been my next try, I have a 36" pipe wrench (if I can carry it up there).

Be careful with the leverage. If you break it off or chew it up so bad the pipe wrench can't grip it any more you are out of options. Take a 2"X3/8" flat bar or something close to that size about a foot long and use it as a drift. Put one end against the lip of the barrel bung and give it a good rap with a big hammer. This might distort the bung just enough to break the rust. If someone could hold something real heavy against the opposite side of the bung as a deadman it would help. You might possibly crack the weld on the bung so this idea is not completely risk free. Of course there is the spark factor when you are beating on steel.

I'm not sure I follow you. This is a gravity feed tank on legs. I'm trying to take off the old flip-up cast iron cap. I'll be working from a ladder.

Used to work for a fuel company. Dealt with lots off those caps and if your lucky a pipe wrench will break it loose. Had a lot of those break off and had to resort to a hammer and chisel to break in apart without messing up threads. Best luck I had was using an off and on pressure but not easy to do on a ladder.

I'm confused. If you are using a gravity feed stand tank how is it going to feed if you have it sealed? My gas and diesel tanks are all vented with the ancient style flip up vent. That's the only way they can fill the diesel tanks with electric pumps at the other end.

Pressure cap holds pressure so it's a few psi to prevent evaporation. Still let's air in as gas goes out
