Quick Question
'69 F250 390
Fuel Filter... before the mechanical fuel pump or after or both?
I've heard after is best, but someone said that if you don't put one before the mechanical pump, it could run dry and burn up.
Thanks
Doug

Mine is right before the carb. This in my opinion would be the best location. If by some crazy chance your fuel pump starts shaving metal this would stop it from trashing your carb. One before and after the pump wouldn't even be a bad idea as long as you get enough fuel. For a stock engine this shouldn't be a problem.

My '70 has a filter has a filter at the pump and again at the carb. My '78 has three filters. One before the pump, one at the pump, and one at the carb.

[font size="1" color="#FF0000"]LAST EDITED ON 20-Aug-01 AT 02:27 AM (EST)[/font][p]I got a Carter special ordered from Kragen that had the filter built in to the bottom of the pump.
I think it's best to have one before the pump to keep stuff from damaging the pump. I think the pump itself is just a rubber diaphram and might be dammaged by stuff from the tank.
