Paul,
After doing some reading at the Racor website, I've got a few questions for you if you don't mind.
Did you install the water probe with built in detection electronics (RK 30880)?
How long have you been using this Racor?
I noticed that you went for the 2 micron filter (R45S) instead of the 10 micron (R45T) or the 30 micron (R45T). Any particular reason for using 2 micron?
Do you know what is the micron rating for the original Toyota fuel filter?
Looking at the the specifications, the 445R seems ideal for our Hilux as it has the lower fuel flow restriction rating compared to the 245R model.
Tempting..............
Cheers
Brendon
