I installed an Airdog 150 (haven't installed draw tube yet) about one month ago & have been very happy w/ it until last week. I was running 14-15psi daily and then it started dropping 1 psi every other day. Now I'm down to 9-10 psi. Prior to installation I ran only dinodiesel. Since the install I have run only 3 tanks total of fuel (all were B20) through the system. Can the biofuel be cleaning that much crap out my tank? I am going to change the filter & see what happens. I need to get a Napa replacement # ASAP.

Am I headed in the right direction or am I missing something?

 

everything I have read on bio-diesel said just that. It will flush all the crap out of your tank when you first switch over and plug up the fuel filter in the first 500 miles. Change the filter now and also the next filter change do it early. it should be good after that. The bio-diesel also has beter lubricity than the dino, so it should help keep things running smooth in the long run.

 

I'm surprised that none of the Airdog dealers have chimed in w/ their .02 worth. Does anyone have the Fleetguard or Napa fuel filter #'s please?
