Gas Tank Screen

I have my 1966 with an under the seat gas tank.

It is old and been repaired-- the original outlet walled off, and the drain hole fitted with an outlet. The outlet thus has no screen.

The tank does not leak, and is clean inside, but again has no screen at the outlet.

This lack of a screen causes stalling when a particle gets sucked over the 3/8 in outlet.




Has anyone installed a new screen-- (how?)

Or rigged the tank with an outlet like a modern tank out of the top.

I am running a carter electric model 4070 below the level of the bottom of the tank mounted to the Jeep frame.


Any suggestions on modifying a stock under the seat tank what has no screen?

 

Screen? Screen? I have a '66' with an electric pump, and I have a fuel filter, but there is no screen (and never has been) in my system. I'm still using the original outlet.

In fact, I have 3 tanks on my Jeep and there aren't any screens on any of them....

to see my rig;

I would think the fuel filter should remove those particles.

No filter screen have I seen on any of the underseat tanks I've had. I'd put a filter between the outlet and the pump. Should have one there IMHO to protect the fuel pump.

 

If you are getting a 3/8 outlet plugged I would either have the tank cleaned and lined or replace it.

 

Only the military tank has a screen. It feeds out the top of the tank. Sorry will not fit into a CJ tank.

 

Tnanks--

Yes of course I have a filter between the gas tank and the fuel pump to keep junk from hurting my electric fuel pump.

Originally in my tank at the gas outlet inside there was 3/8 steel tube about 4 inches long inside the tank that was bent at 90 degrees and exited the tank.

The end of the original tube had a small round screen about the size of a flattened gulf ball. But the gas exit tube was rotted- and leaked where it exited the tank. So I removed the original tube and fiberglassed the original gas outlet shut inside and out-- and mounted a brass fitting in the drain plug hole where a 3/8 gas line is fitted.

Now the drain plug hole serves as the gasoline outlet. What has happened is a ten-cent sized piece of tin foil somehow got inside of my tank and was sucked directly over the 3/8 outlet stopping the flow of gas to the fuel pump stalling the engine. Also a tree leaf somehow found its way inside, along with some balls of paper that look like someone put some toilet paper or kleenex in my tank.

I suppose it was just a freak event. Anyway if a domed screen was over the gas outlet it would stop some of such events from being possible or happening. But the Toilet-paper or Kleenex thing would clog any tank screen or not.

 

What would more than likely happen imho is that screen would plug up and make it even more difficult to service. I'd much rather have an external filter that was easily serviced than one more inaccessible. I've experienced that in some carbs that had a similar screen and you had to disassemble the carb to get to it. It was a real pita to fix.

Sounds like you got it figured out. Great!

 

This looked like a chewing gum wrapper, but an additive bottle seal could to the same thing.


I took the tank out-- and the sensor top off, and cleaned it. Perhaps I should convert to a new rear tank.
