How about these?
Filters
And they are not to far from you?
Those are for a 7.3 and
WAY to expensive. I can get Wix from filter1 for 15.19 and 16.59 (with or without water sensor port). $29.95 is high!
Part numbers are 33417 (no water sensor port - $15.19) and 33617 (with water sensor port - $16.59). I know some like Baldwin, but in my book, you can't get a better filter than Wix. Seen them in action on a warranty, I won't buy anything else!
In any event, he won't be able to use them until he finds a 7.3 filter head. The only ones I know of that will work on a 6.9 and work as the 7.3 filter does is the Racor ones. I think MWFI has them listed, but they always seem to be on backorder and are very PRICEY!
