OT-OF-HERE!! said:
I just cleaned my AFE filter last week and just noticed last night that I had pulled it down into the RED!!

Is anyone running some other filter that fits that box and tube setup?
Perhaps it's pulling down into the red for two reasons:
1) Might you have over-oiled the filter when you cleaned it? It would be harder for air to flow if there's too much oil.
2) It's winter, did the filter get rain soaked? My AFE got soaked every time it rained, so I pulled it off altogether. I just ordered another filter plus a pre-filter. I'm hoping the pre-filter will keep the water off the main filter.
I looked inside my Torque Tube, and could see where water and oil had pulled through and ran down the inside of the tube. The water caused the aluminized tube to corrode. You could wipe your finger inside and it would turn white. I also checked my turbine blades and they were sticky.
Keep in mind this was with a brand new filter, not a cleaned and re-oiled filter.
I just received my "Cool Blue Hose" and am waiting for my PG7 replacement to arrive Friday. I hope this solves my problem of the filter getting wet.
I thought the "Cool Blue Hose" would solve the possibility of corrosion in the pipe. When they told me the hose was internally braced, I had envisioned wire wrapped inside the silicone. Nope, it has two steel rings (sections of 4" pipe) pushed inside the hose. I suppose they could rust/corrode as well. We'll see. I'm thinking that the new Torque Tube design might be the best.
