I am working on my upgrade to EFI and am going to use a external fuel pump, my question is should i put a fuel filter in front of the pump to so i can make sure no junk gets into the pump. I know the pumps don't suck real well but do you guys think that a small filter will still allow the pump to work fine?

I would put a filter in front of the pump to protect the injectors. If your tank has a sock on the pickup you should be ok behind the pump. If not put a good factory style filter behind the pump too. Filters are cheap but efi pumps are not.
I was just wondering if the pump will still be able to build up the right pressure with a filter before it also. I want to run one before the pump to make sure that it is protected because they are not cheap
I would say that yes the pump could build enough pressure to run properly with a fuel filter in front of it, but the problem with a fuel filter before the pump is if the filter should become dirty enough to starve the pump (even a little), it could burn the pump out because EFI pumps use the fuel as a coolant to keep the tempretures it's down.
