So...I am running some Sea Foam through my fuel system and was worried it would dredge up a bunch of gunk from the tank and plug up my new OEM fuel filter (and of course you can't see into that one to know how gunked it might be). So I installed a see-through fuel filter in front of it to catch any gunk. So far, no gunk -great. I'm wondering however if there is any downside to two fuel fliters. Can I just leave it in or will it tax the fuel pump more than just one meaning I should pull it? On that note, any reason I need to pay xtra money for an OEM filter rather than just using the much cheaper plastic one? Thanks!
