A```ha, that is one...
We have already covered his filtration here.... You had better get two hydraulic accumulators instead of one.
He advised me to keep my check valve, priority regulator, and moisture/CO indicator on my small on-board factory filtration canister. I can check for moisture at the final stage on my Lawrence Factor filter moisture monitor strip. Kinda makes sense to me, but I'm sure others will have varying opinions.
Toss the CO spot detector, its basically worthless.
The little strips that they sell with those don't turn until 40% RH is reached. That's too wet, definately wetter than grade E gas. Get yourself a 10/20/30 RH disk from Texas Technologies. 20% RH at 2200psi is roughly the grade E moisture limit.
The strip in the LF canister will never change if you are changing your primary filter at grade E limits and using the 2nd filter as a "backup". That's how I use mine. I end up changing my 2nd filter every 60 to 70 hours which is roughly is rated capacity. Fortunately it doesn't do much work, there's probably 30+ more hours of life to it. But for $45 its cheap insurance.
