Every time you open that pump you introduce dirt into that fuel system i don't care how minimal you think it is. Your filter is 2 micron!! The human eye can't even see something smaller than about 50 microns. Just rebuild it every 400k and then forget its even there. Personally I think it's foolish to open your fuel system any more than is absolutely necessary. I feel the same way about these guys that run the overhead once a month, taking the lid off, knocking dirt/debris in there, its just unnecessary and most likely harmful in the long run. That's my 2 cents anyway.

I feel like we've had this conversation before.
