gas tank

Re the strange design of the plug, mine is the same as a standard 1/2 in drive ratchet, just like the differential plug.  Just put it in and turn it out.

For mine I left the bottom plug alone.  It wasn't leaking so why mess with it.  Besides I don't believe I have noticed that part for sale from anyone maybe it is but I haven?t noticed.  Between the gas gauge hole and the fill hole they should be OK.

My 2 cents...  Chet

That underside bottom plug has a weird configuration.  Is there a special tool for it?  And is it necessary to take it out anyhow, if I take the tank to a radiator shop to have cleaned?

Thanks Chet and Dave for the information.  Will do as you both suggested.     Ed

I just bought a 47 plymouth coupe.? Hasn't run in 8 years.? Motor turns over, but doesn't fire up and run.? Is the gas in the tank and fuel line bad?? Assuming it is, is there any simple and cheap way of cleaning them out?? I'm new at this game, bear with me.? ?Ed

Ed,

Dave is correct if the problem is fuel.? There are a number of reasons why a motor will not run and before you chase anyone of them you need to do some trouble shooting.

Are you getting spark to the plugs?

Are you getting gas to the engine?

Is the timing correct?

Do you have compression?

Gas, spark, timing, and compression are the four main ingredients to a running engine.? In your case which one is missing.

Sorry but you can spend a lot of time chasing the gas tank when the carburetor jets are clogged with lacquer and you are starving the engine for gas. Maybe your gas filter is clogged, maybe your fuel pump is not pumping or maybe the list goes on and on.?

Tell us what is known good about your engine.?

PS? to get fresh gas to the engine you could bypass the gas tank by disconnecting the gas in line to the fuel pump and inserting a hose connecting fitting.? Run a gas hose from a gas can to the fuel pump.? As a help get the gas can a little higher then the fuel pump.? An old fashion milk crate is the right height.? Also clean out any gas line filter between the carburetor and the fuel pump.

When you work the carburetor do you see gas coming out of the acceleration jets???

My three and one half cents?.

Chet?

Chances are the tank is in tough shape although you may be lucky. A sniff test will tell you. There is nothing smellier than old gas. It will have to be drained and the tank may need to be boiled out by a radiator shop. The fuel pump may also need attention.

If the fuel system is ok, cleaning of the ignition points and priming the carb bowl should bring the desired results.
