MRAP Air Tank Changeover

[TwistedOaks]

Has anybody done it? I like the aluminum construction. They're about 1 foot longer than the standard primary tanks. But the last foot of them are (what I'm guessing is) an auxiliary? Looks like a check valve inside. Lots of ports. So my question is, how would it work with the auxiliary built in? I can't find any TM's on the MRAP that detail how these tanks are supposed to function.
Why do I want to do this? Well, I'm putting a M915 battery box under the passenger door, and moving the primary and secondary tanks to behind the updated tool box I added 6 months ago on the passenger side. When I pulled my current tanks, it sounded like gravel inside. So I figured - why bother going back to steel when these tanks are available for around $40 NOS.

No, but I am interested.

I have 6 of those tanks. I am going to run a T into the main air supply line and run it to a 2nd air dryer and use 4 of the tanks to supply air to the future CAT 7155 install so it has its own air supply separate from the brakes.

Wes I don't know how you find the time for all that you do.

I pressurized the tanks this weekend, just to test. Good to go. I'm a little confused as to the purpose of the smaller side of the tank. I'd assume the smaller side is meant to be used as the primary, with possibly an actuated valve in the event of pressure loss that would open up the larger side of the tank?



As of now I'm planning on using the larger side as a primary and plugging up the smaller.

I tried to buy some of the tanks off ePlay, but the guy screwed up his auction and cancelled my order of six.

Yeah... He does that. I bought a hardtop off him last year, and he had some really weird hours. I think it's a lack of coordination on his part. When I got the tanks last week, he said that site was screwing up his shipping costs and was going to cancel my order in 24 hours if I wasn't willing to pay the extra $15 for a second tank shipping. He did ship REALLY fast.
