ARB Dual Air Compressor -- run hoses to each tire or just use one long hose to air each tire up separately?

[J0E]

Does anyone have any experience with both the Innovative AT system vs the Krackenor reviews? I can’t seem to find any and I’m waffling between the two. Wish the Kracken had a pressure gauge…. Wondering if one of you has installed an/or used both.

The Innovative AT Products looks like the way to go. I don't want to run my car just to get mediocre at best pressure readings. The lack of a pressure gauge is a huge design flaw. Let us know how you like it.

Wouldn't it be simple to add a pressure gauge to the Kraken if that was deemed to be critical?

Note that I've always run my car Jeep when running the air compressor. I assumed that others do the same so that load isn't being put on the battery alone, but, as always, I could be wrong.

You could add a gauge. I don't know anyone who doesn't run their engine while pumping, but it's not necessary. I can inflate all four 37's, front at 13 PSI, rear at 10, to 30 PSI off one 6Ah battery using this pump. Normally I run 4 pumps simultaneously with four 4Ah batteries and they're each 25% drained when finished.

I was very skeptical that you get more reliable pressure readings with the engine running, but after testing a dozen times with the engine off, once I start the engine I get more reliable readings within seconds, but the best readings when I drive a hundred yards. Maybe the engine vibration helps? I've also heard many others report you get much better readings with the engine running, so I no longer doubt it.

A couple days ago my TPMS wouldn't register any changes until I cranked up the engine.

Yup, I wonder why it's so unreliable without engine running. My guess is the engine vibration.

I have the Kraken. Engine running and I look at the psi readings on the dash. Easy peasy. I like being able to hook up all four and climb inside if the weather is pissy. It is self equilibrating as well.
