Fuel Filter.

I'd read on Brickboard that an often overlooked cause of poor performance is a clogged fuel filter. I'd been experiencing poor power, but I'd checked my filter and it looked clear, so I didn't suspect it was a problem.

Given the fact that fuel filters are less than $3 at the local auto supply (Fram G4164), I figured it couldn't hurt to get a new one. I was glad I did. After removing the old filter and comparing it to a new one, I realized it was dirtier than I'd thought.


notice the dark matter at the bottom of the old filter

While I was at it, I decided to throw an extra filter on the line before the fuel pump and change all the fuel lines (5/16" from the tank to the fuel pump, 1/4" from the pump to the carbs). The old lines, it turns out, were getting pretty hard. Total cost for filters and lines was under $10. Inexpensive fixes that I hope will prevent future problems.


filters before and after the pump, new lines and toothless hose clamps all around

you should see what the filters look like on one of my diesel's sometime. I think I found a jellyfish in their last time.
