My 411 SSS (with a 1600 R engine) keeps eating fuel pumps (now on number 3). I am finding sediment in the glass fuel filter bowls and when I take apart the fuel pump I see particulates in the catch screen, but only a small number (<5). But something in the fuel pump ceases to work even though the diaphragm looks fine. Are the particles lodging in the check valves? What is breaking in the fuel pump? If I replace the check valves will that fix the pump?
As to the source of the problem I've taken the gas tank out and inspected it -- it looks clean and shiny inside (its galvanized) - so I gave it a good dump with water and reinstalled (haven't restarted it yet). So I'm not sure where this crap is coming from ---
This car runs a glass bowl filter, I'm thinking of installing another filter in line with the glass bowl filter. The PO had installed an electric fuel pump at the tank which I've re-hooked up but I"m leary of running for safety reasons. I'd much prefer to keep the mechanical pump for both originality and safety.
Thanks
John

Re: Eating Fuel Pumps
I would suspect the check valves being damaged. It should be easy enough to test or check. Adding a disposable filter inline would not be a bad thing.

Do you have the spacer between the pump and the block?
If not you are over extending the pump lever and that will kill
the pump.

Re: Eating Fuel Pumps
Add a fuel filter before the pump.
Might be crude from the tank or lines that's getting in the valves. If the inlet valve has any leakage, the pump efficiency goes to hell.

Re: Eating Fuel Pumps
Always thought the filter came before the pump anyway.
