I have a little over a thousand miles on veggie. I work at home and just run around town with lots of small trips, a few 1 hour trips per month so a thousand miles too awhile :-) I have the fn74 setup and it works great. I want to make a change soon and relocate the fuel pressure regulator (fpr) to before the filter, it's really hard on the pump as the back pressure in the filter builds up. I understand Jason is making the change also now that he is using heated filters too. Just replaced a filter for the first time, I am not happy with the mileage, but it's still less than 20 cents per gallon for the filter [img]/ubbthreads/images/graemlins/smile.gif[/img]
I suspect that the present setup with continuous flow through the fpr causes early filter demise, and although low miles for a filter, there were pretty high hours in running. Now with a successfully operating filter heater, relocating the fpr will cause only one flow through the filter, and allow the pump to see the same head pressure regardless of filter clogging, for its lifetime - saving $300 for replacement pump and likely extending filter life.

One little note which may be of warning. I drained my water separating truck wvo filter recently (just before replacing it) to see how much water had accumulated. It drained about a quarter cup of water, but a short time later it started leaking heavily without my knowledge. I hope the people in the mall parking lot look where they are walking ;-) I didn't have any dry sweep on hand to handle the 4 foot long spill while idling for a bit. SO I might suggest that draining the filter body would be best done with the engine and pump off and the pressure purged from the system somewhat, as I couldn't turn that Fleetguard drain fitting to make it stop spraying oil no matter what. Gets the blood pressure up a bit when that kind of thing happens. Live and learn.
