No. The TP3018, like the Racor PFF50216, are for the stock filter head.
Miles is not necessarily a proper gauge for change intervals, gallons used would be more accurate.
After my LP install, following the DIC %, I changed the first two filters (either side of the LP) @ 0%. On the 2nd two, I wanted to see how far it'd go, so when I reached 0%, I reset it and kept going.
@ 40% more (60% remaining), I started to feel a difference in power pulling heavy and went ahead and swapped them out again.
At that time, I went ahead and removed the stock Racor up front and cut it open to inspect. That tertiary filter had approx 3000 gals of fuel ran thru it.
You can see the pics of the guts I posted on my LP kit thread.
Sparkling clean, thru and thru. I wasted $35 cutting open a perfectly good filter, just to satisfy my curiosity. And to verify that the 1st two filters were doing their job, as spec'd.
It's now been 6 cycles of filter changes for the 1st two, and a fuel limp popped up the other day. So, I thought I'd order a new one, swap it, cut it open and inspect to see what's up.
With all fresh filters, you can establish a base line for monitored fuel pressure. Then check it later on down the line, looking for any changes that would point toward a restriction, not just guess at a predetermined mileage mark.
There was a member posted not long ago, running the stock filter after the fass filters.
They pulled the 3rd filter, cut it open and it was black, not white. The famed fass filters weren't doing the job as advertised. And the User was very glad that they chose to keep the stock filter up front.
