decided to take apart the old fuel filter to see what was inside, and found the filter material was black - also some gas came out of the intake nozzle of the fuel filter, and it was black. could the fuel line be going bad, or is this normal?

 

wait - you are saying the gas itself was black?

 

No, this is not "normal" and yes, rubber does deteriorate over time, and the car is 15 years old...but again - I drive a 1990 that still has some of the original fuel lines on it in the tank vacinity - under hood lines have been replaced since they are subjected to repeated heat/cool cycles causing faster deterioration...

 

that said...you also mention "fine dirt" in the bottom of the tank...I would suspect that this is what is killing your fuel pumps prematurely, if it is fine enough to get past the pick-up screen. when the car is running it is going to stir that dirt up making it easier for the pump to suck it in.

 

as for how to get the dirt out - you could try to suck the dirt up using a siphon hose - keeping the end of the hose down close to the bottom of the tank and moving it around as it sucks the gas/dirt up - similar to cleaning a fish tank if you have ever done that....

If you can get your hand through the opening, siphon out as much as possible. Then use clean (preferably lint-free) rags and wipe the dirt out. Careful though as the fumes will be strong and any spark (even clothing static) can ignite it. Other option is to drop the tank and rise out with water after the fuel has been drain. 

 

Are you using a new strainer with each pump? Many companies won't honor a warranty if the old strainer is used. Might also want to try a heavier duty fuel pump like what the turbo cars use, or maybe what the AWD cars use (2" diameter pump instead of the 1.5" pump).

Concerning an earlier discussion in this thread: The speedometers stopped working on both our 91 and 97 Postal Legacies with around 150,000 on original and on replacement transmissions. The problem each time has been the nylon gears in the front differential that drive the speed sensor. No speedometer love without pulling the transmissions and rebuilding or replacing. This has been a serious PITA for the '97 which will not pass emissions testing with the OBD II carrying the speed sensor code.

I was working on the timing belt a week ago. but everything back together and the car would not start - no gas. Looked at the car the following morning and decided to take a look at the infamous fuel pump relay, pulled the relay (after what seemed like an eternity trying to get it out) and made a jumper wire to the fuel pump and it fired up. So I guess it was the fuel pump relay. Thanks for the help.
