1974 Plymouth Satellite Sending unit

'73bird · May 21, 2018

can I remove this without dropping the tank. The car is on my driveway which is on an incline and gas is leaking out of the sending unit I mistakenly bought with a return line which I have attempted to cap with no luck. I am going to buy another without a return in order to remedy this. I remember what a pain it was putting in the tank by myself on this driveway.

Personally, I suggest you try to re-cap the return. Maybe you could use a short piece of fuel line, 2 clamps & a bolt with some RTV on it? If you get the *** end of the car up in the air (jack stands & wheel blocks of course) you can get under it & re-cap the return. IF it's leaking from the gasket itself, then you have to drop the tank.

So no taking it out without dropping the tank?

Just a thought, Are you positive it is leaking from the return fitting. I would almost bet since you just replaced the sending unit it is leaking from the sending unit gasket. When I replace the sending unit I always plug both the return and the fuel supply tube and stand the tank on end so the sending unit is the lowest point on the tank and fill the tank with a couple of gallons of fuel and check for leaks. I leave the tank standing on end over night with a paper towel under the sending unit for tell tale leaks.
Just a thought. Also you can siphon/fill the tank below the sending unit and check for leaks.

Yes, you can get the sender out without dropping the tank.

...at least you can on a 73.

When I put the new sending unit into the new tank I used a new ring and seal

The new rings SUCK.

Metal is too thin and diameter is too small.

Use a period, vintage OEM ring.

...and my new seal deteriorated in less than a year.

I found something else at Lowes that worked though and it has lasted almost 2 years and counting.

A toilet tank seal IIRC, the kind in red rubber. Nearly the perfect size.

The in tank seal from where the reservoir connects to the bowl? O and I thought the new rings only applied if you were using a vintage tank that was refurbished.

If you used a new lock ring, that might be your leak cause right there.

It was on mine.

New "quality "Canadian" tank.

Good thing I tested it while I still had the old stuff.

NO CONTEST between OEM and repro lock ring. Worth saying again- NO CONTEST.

Never had the old stuff. Car came with a rusted out tank which they wouldn't even dip and no sending unit or ring

There was a member on here selling OEM rings a little while ago.

Well put the new sending unit in and tipped the tank no leaks. I now have a 3/8" 1974 Plymouth satellite sending unit with return if anyone wants to buy it.
