So I did the harpoon/hutch mod but I need to get a pre filter. Wheres the best place to get one and what?
Also, Im going to be having an injector shop building my sticks to 175/100%. Should I upgrade my pump for these? Ive been thinking for a while about the airdog2 but have heard recently about some issues with them.
What about a regulated return too?
Any thoughts, suggestions?
If you going to upgrade your sticks then upgrading your fuel system is a good idea. A popular filter for a pre-pump filter is the baldwin BF1212. 20 Microns absolute, 93% efficient at stripping water and can flow 300 gph (your 7.3 will require about a tenth of that).
I would avoid Air Dog, their filters are not that great and can be a PIA to get IMHO and the pumps are so-so.
What is the FRX you mentioned?
FRX is offered by Riff Raff diesel, basically it eliminates the deadhead by tapping into a pair of rail plugs in the head. It still retains the factory fuel bowl and incorporates the fuel pressure regulator shim into it. For stock and small injectors it should have no problem keeping up.
Do you have a fuel pressure gauge? If not I would get one just to keep an eye on things.
