Really learned a lot about fuel with these small micron filters.
I've learned that fuel in Texas can really plug one of these 7 micron filters up quick. It's not just coincidence from one or to fill ups. Be it pilot or TA, the fuel struggles to get through a 7 micron filter when cold. I guess it's a combination of the bio content, and lack of winterization.
I fueled at the new TA in Hillsboro, TX on my way to Laredo, and topped off their again on my way back up. Weather was really warm (almost 90). Checked my fuel filter when I got home, and it was only 1/3 full. Temp dropped off cold while I was at home, and I ended up having to put a new filter in 50 miles from my house because the filter was totally plugged up. Had the weather not gotten colder, I would have been fine.
Even with the new filter, restriction gauge was reading 5. Ran the fuel down really low and fueled again in Brooklyn, IA. Restriction immediately dropped down to 1.
Before this truck, my Davco filters were just a 25 micron filter because I always had a 2nd filter in the system, so the different fuels were never an issue.
I got in a bind this past week and used a larger fuel filter than what my Davco calls for. It's the 382, and I used a filter that is made for a 382 with the larger bowl. Filter fits, but not alot of room for fuel outside of the filter. Ordered new filters, and planned on replacing it ASAP. Waited too long, as it was in the truck still this morning when I started it after consecutive days of temps dropping near zero. The result? lots of restriction! It ran though, performance wasn't really an issue, so I got the delivery made this morning, reloaded, then got the filter replaced.
Had it been much colder today, I may not have been moving.
