It starts with ether in the carb intake but doesn’t stay lit. Checked fuel pump and seems like it’s working but my not be getting fuel from tank. Anyone know about a fuel sender in the tank or have similar issue they’ve dealt with. I’m original owner and only has 150k miles in it. Would like to get it it back on the road. Any help is appreciated!

TX22R...This is a great engine and desirable model with a simpler fuel supply system.  1982 is still a carburetor and mechanical fuel pump.  The carburetor should have a sight glass, and if you can see through the glass, you should see fuel in the float bowl.  With the ignition OFF, check down the carburetor throat while opening and closing the throttle.  See whether fuel is entering the engine intake.  If fuel is in the carburetor bowl, there should be squirts when you move the throttle.

If there is no fuel in the carburetor bowl (sight glass view), I would disconnect the fuel line at the carburetor.  Hook a hose to the line, and route the hose safely into a steel can.  Have someone crank the engine for 20-30 seconds while you watch for fuel flow.  Gas should flow well in steady pulses.  The pump strokes should provide adequate pressure and fuel volume.

If no flow, 1) the fuel filter could very well be clogged or 2) there is a restriction in the fuel tank or kink in a fuel line.  If there is reasonably good fuel pump flow, and the carburetor is empty, the carburetor's needle/float may be sticking closed.  If that's the case, tap gently on the top of the carburetor (where the fuel line enters the bowl) with the handle of a screwdriver.  This can dislodge a stuck needle.  Test again.

If there is a normal amount of fuel in the bowl and squirting down the carburetor throat, the fuel could be stale and unable to fire.  Drain the fuel tank if necessary, there should be a drain plug on the 1982 model's fuel tank.  (The skid plate needs removal to access the plug.  Be careful loosening an older drain plug to avoid damaging the tank.)  Add fresh fuel.

If the pump seems okay (tested on the bench or engine for both pressure and fuel volume) but there is no flow from the tank, the restriction could be the fuel pickup in the tank.  The fuel pickup assembly is separate from the fuel tank sender.  The pickup assembly should have two tubes (the pickup tube and a return tube) at the top plus hoses.  The pickup has a sock filter at its end, and these socks can get clogged over time—especially with a long parked vehicle, tank sediment, water/rust or gel from stale fuel.

If you narrow this down to the fuel pickup in the tank, you will need to drop the tank and remove the pickup assembly.  The sender has an electrical wire attached.  The sender has nothing to do with the fuel pickup or supply lines.  Your concern would be debris in the tank and a clogged fuel sock filter.  Clean the tank thoroughly or consider having it flushed/hot tanked at a radiator shop.  Shops can coat a tank after cleaning it.  If badly corroded, consider replacing the tank with a new one.

The sock filter in the tank is important, so don't eliminate it.  Install a new replacement filter.

Let us know what you find...
