I've spent a good amount of time this morning researching fuel filter options. I don't like that the popular NAPA base loses many of the desirable features of the stock unit, so that's out. I don't like that the Stanadyne base is plastic, so that's out. Racor seems to be fairly popular, so I looked into that next. I want a heater, water separator, and a hand pump; a WIF sensor would be nice, but not entirely necessary. Based on my research, the stock lift pump options were capable of pumping up to 32 or so GPH (from memory), so 30 GPH rating is marginal, and better is preferred. The DB2 wants 5 micron minimum filtration, so that's the other major limit. Racor has two models that fit the bill: 245R and 445R. Adding "122" to the end of each part number adds a 12V in-bowl heater and 2 micron filtration. The 400 series has an available WIF sensor add-on, but as stated, it's only a nice-to-have. The 200 series has one inlet and two outlets, where the 400 series has two of each. The stock unit has one of each, so either are fine to overkill for my application. The decision is essentially down to port size... The 200 series ports are 1/4" in and out and the 400 series is 3/8" in and out to the stock unit's 3/8" in and 1/4" out. Given that both have the same 45 GPH flow rate, I don't think the 1/4" inlet should be a major limiting factor with an extra fitting but I'm not completely sure about that. The 3/8" out is obviously not an issue, as that can easily be choked down with an extra fitting, but there is a $70 difference or so between them for that...
Does anyone have any input on the limitations or lack thereof inherent to a 1/8" choke on the fuel filter inlet from stock?
