That is a Force version of the original Chrysler t/t system. It has the later model 2 wire motor/pump with screw-in check valves. The check valve for holding the engine up usually goes bad first. So, you can gain some service time by swapping the check valve from the visible side with the check valve facing the transom.
However, rebuilding the check valve is not difficult. Brace the engine so it will not fall or put it all the way down. Then using a 1/4 inch Allen wrench (L shaped hex) simply unscrew the valve. there will be two O-rings on the valve. Remove the small one and carefully use a tool in the groove to pry off the small cap with a hole in the center. Inside will be a needle and spring with a very small O-ring. They may pop out so don't lose them. The ring will probably be broken or completely missing. Replace the O-ring. If you search other threads I think a Techumpsa carb kit has the correct O-ring in it. Or perhaps someone else will chime in with a source.
Press the cap back on the valve using a very small amount of lock-tite, replace the O=-ring you originally removed, and screw the valve back into the pump body.. New O-rings on the valve would be a good idea too, especially if you damaged the smaller one removing it.
