Re: [DML] Fuel Pump Seizure

[Martin Gutkowski <martin@xxxxxxxxxxxxxx>]

We had a similar xperience with a customer and it turned out to he an 
intermittent blockage in the fuel tank. I myself discovered how dirty 
"new" tanks are with my pickup filter getting blocked after a day or so 
of driving. On that particular pump, putting reverse voltage on it frees 
it up, then it'll spin again the correct way but it doesn't actually 
pump anything!

Best Wishes
