    I assume you are talking about the big primary fuel filter mounted on the passenger side of the engine? napa has them.

    I’d put a water separator filter before an electric pump.

    I honestly think you will be better off with getting a spin on filter assembly. The spin on filters are a lot easier to come by, not as messy, and probably filter much better. JMHO

    On my frame rail, after the FSV and before electric pump.
    Mine is a powerstroke, but you can do IDI the same way. I have a second fuel filter after the pump.

    I use that model filter because it’s about 5 inches tall, frame rail protects it.

    These are a good option:
    https://ph.parker.com/us/en/diesel-fuel-filter-spin-on/120at

    That lets you delete your factory W/S too, if you want to do so. My RV's W/S was gone when I got it, so I put a Racor head I pulled off a junk yard IDI years ago in the same spot as the factory W/S... which is how I found it on the salvage pickup it was on.

    I have it installed after the Holley Red fuel e-pump (mech lift pump deleted) so my system is like this:

    [tank]-[e-pump]-[Racor W/S filter]-[stock fuel filter]-[IP]

    I need to go put back the pre-filter before the e-pump. I removed it when I was diagnosing fuel pressure related timing issues. It's a cleanable/replaceable element one and it was leaky, so I might put a solid metal one and just replace it once it once a year since I can't see inside. It's too far from the Racor to bother running hoses back and worth, or I'd do that.

    I have the same one. There is an even longer filter for it.

    I put mine on the bottom corner of the fan shroud. It does not hang too low.

    I had one similar to yours on my truck and one day something shattered the plastic or nylon bowl on it, that’s why I changed to filter style with pet cock for drain.
