Relocation of Renix 4.0 vacuum canister

Recommended Posts

I bought a new front bumper that is marketed for an XJ for my MJ build. Of course, the vacuum canister "ball" that was mounted in the passenger side of my stock front bumper had to be relocated. The XJ specific instructions, which appear to be for a well optioned XJ with cruise and A/C, would have me reroute most of my vacuum tubing and put the canister right about where my washer fluid reservoir lives ahead of the master cylinder on the driver's inner fender. This was more relocation than I was in the mood for, so I looked for an alternate location.

 

Since my 89 Base Comanche still has the Renix era cooling system puke tank located on the passenger firewall, it looked like there was plenty of room to mount the vacuum canister under the puke tank, so I removed the bracket, painted it with some rust inhibitor and drilled a couple of holes to secure the vacuum canister.

After remounting the bracket and puke tank, I connected the vacuum lines and patted myself on the back for a job well done.

That's a great spot! I just screwed mine down behind the relay panel near the battery. Much easier to get to if needed. Your spot is easy and tucked out of the way. Good job!

My Comanche has the large "squash" sized canister, Can I install this smaller "ball" sized canister and be fine?

The lage reservoair is actually two, it has two isolated chambers.

I cut mine in half since one chamber already was plugged.

Out of sheer curiosity, say someone's vacuum canister wasn't all there, like it had gotten into the tire and had a giant hole rubbed through it, would that cause major issues like stalling and a poorly running vehicle? because it looks like that is what happened on my 87 4.0.

that would result in a giant vacuum leak for sure.
