MG TD TF 1500 - SU Fuel Pump TF

My fuel pump was converted to SS by Dave Dubois several yrs ago (I hope he's still here). It's rear mounted near the tank. It worked on Tues., but it kept pumping, as there was a fuel leak. The next day it wouldn't pump, and hasn't since. It appears to be "stuck", and is drawing 4 amps. Tried tapping it, but space is restricted, so can't get a good tap.
Is it fixable? Any thoughts welcome. tnx, Al

Dave passed away several years ago I'm afraid. It sounds as if there might have been a blockage between the fuel pump and the tank and you may have damaged the pump. Dave often talked about this as a reason to not have a filter between the pump and the tank. Removing the pump and checking the screen filter in the pump would be something to look at as well as removing the outlet at the tank and checking the screen filter there as well.

Best of luck.

Thanks LaVerne, I'll get a look at them, but it sounds like I've got a bigger problem. We'll see.
And thanks again for sending me that "finger rack" for the TF grill slats, during my rebuild, 10+ yrs ago. The missing one never showed up.

Frustrated today -- removed the pump, filters are clear. Took it apart, things looked good, and moved. Suspected a problem in the SS conversion, a very neat and professional job by Dave Dubois. On the bench, applied 12vdc and it worked!! Reassembled, still worked. Now, back in the car - tomorrow. Need to figure out why it wouldn't work in the car, had checked wiring, all seemed good.

Al, what part of NC are you in? I'm just across the border about 6 miles southeast of Tryon.

Is it possible that the screen on the end of the fuel pickup tube inside the gas tank is horribly blocked? If so, this would prevent pumping (just like a clogged pre-filtre) and lock the pump in a partially-pumped condition.
