Loads of people get away without using the internal tank pump but either the in-tank pump has to stay or you replace it with a strainer (from a 928) otherwise the external pump won't last long.

In-tank pumps are repairable, they just gunge up and seize. Seized in-tank pumps usually allow fuel through freely but sometimes they don't. If you can't repair it one option would be to disconnect the pump part and use an external inline fuel filter before the main pump.

If you don't have a working in-tank pump, try to make sure you never run out of fuel, the main pumps soon die if run dry. In the same ideally you should try and prime the main pump if you have had it disconnected.

Great information the internal pump had a break in the field coil so short of rewinding pretty much junk. So I am taking the second option. I run two pumps on my procharged Corvette but that is only to boost the stock pump. I certainly do not understand the price being asked for the internal pump. Its a simple two blade permanent magnet pump with a Purolator filter spot welded on the end. Thank you.
