Thread: In-Line Fuel Filters

Tweet

Is there a problem with running a filter after the mech fuel pump, up near the carb, or should it go prior the fuel pump. Seems to me, alot of guys run a filter up near the intake (maybe thats just for bling...???)

How 'bout one of these from Speedway?

Rules of thumb I was taught

Electric pumps = before the pump
Mechanical = after the pump

It seems to me that having the filter near the carb, gets thedebrie right before it goes where you don't want it to go. I haven't heard of anyone with problems related to standard in-line fuel filters. On highperformance high fuel demand engines, I don't know? I also like the glass ones for the visability factor, but have also experience the glass shatter(on my motorcycle, now I use a billet one, and just routinely check the filter screen when I do an oil change. Works well! Barb I like the idea of the plastic ones, I just wish they were prettier!

I typically run them both before and after the fuel pump. That way I catch the big junk before it gets to the pump and anything small that gets past that has one more shot of being caught before the carb.

I been to couple shows sponsored by local car clubs. Glass tube filter are not aloud. For fear of braking causing fire. I have filter befor and after pump.
