It's time now for my fuel filter and pre filter change. I've done a fuel filter on the truck before but now it's time to do it again, and also the pre filter. Should I do the fuel filter first, prime the fuel filter then do the pre filter? Or do the pre filter, prime then fuel filter? Thanks!

 

Prime once the fuel system is sealed and done. Doesn't matter which happens first, might save you a mess to drain the canister first though.
