RE: fuel pump
About the only difference between the manual and the electric pumps is that you have to crank the manual ones. Ipicked up my pump with a bunch of other stuff about three years back. It was well used then, and I"ve pumped about 15 gallons through it since I got it. No signs of trouble. I thought it had gone bad once until I noticed that I had bumped the switch on the pump and it was runing reverse from that power pannel switch.
If they go bad and quit pumping, check the pick up line to the pump. I've had two of them go bad on me, one broke off at the fuel level and the other broke at the niple on the jug top. If the pump does go bad, it usually starts leaking because the tube that is the hart of the pump is cracked and leaking.
