On that 379 you should have a lot of room under the hood along the frame rail. Here is a picture of mine on my FLD 120

Anywhere you can find room to mount it. The filter canister can be pretty much anywhere because it is pressurized.

The evaporator canister is non pressurized and gravity feeds back into a non pressurized port on the engine. Just make certain the evaporator unit is mounted about 10" higher than the engine port in order for it to flow properly.

My OPS-1 on my 02 pete 379 with a Cat, is on the right frame rail right behind the steer tire. I will get a picture later.

I had mine done at the local Mack dealership and they mounted mine in exactly the same spot as the Peterbilt's was mounted. I was sort of worried about road debris hitting the filter at first. However after several months of use it has proven an unfounded fear.
