Using P38 air tank to inflate tyres

Hi

From what I understand, these things are designed for tough environments, so I don't think the under bonnet heat will be an issue

Is there a special reason you don't want to just buy a decent battery powered portable air compressor to inflate your tires? They are much cheaper, practically disposable compared to the cost of a EAS compressor and easier to use considering all the mods and such you are working your way into. They are small enough to fit in with the spare. I use one to refill my tires after they've been deflated for a romp on the beach and it works well for me.

Hi Ringo,

I have a separate portable compressor for my tyres as well, but I like this idea for two reasons;

First; if one compressor goes down, the beast keeps running

Second; you can have a very useful air supply connection under your bonnet :p

Bingo.

I did it for the exact same reasons.

A spare portable compressor comes with me for trips where I know ill be up and down a fair bit in tyre pressure. The convenient thing about twins filling the EAS is;

- Quicker tank fill time (less compressor run time)
- Quick and easy tyre inflation (get out the hose and you are done)
- Backup in case one says goodbye
- Can run short duration air tools from it (think about changing a tyre in the middle of summer out bush with a rattle gun - much more pleasant)
- Can fill up the tank via other/servo air with the schrader/nitto fitting
- It just speaks bulk air awesomeness when you open the bonnet (beer and mate bonding sessions).
- Can have mum pumping up the front tyres while dad does the rear (his/hers wedding ideas??)

I think you catch my drift!

Anybody put a larger or 2nd receiver in? That would be a worthwhile upgrade.

Added a second air tank today alongside the original. Not plumbed it in yet. Will probably wait until I have an extra compressor before plumbing.

Bulk air! I like it!

Looks a bit bigger, say 15L?

It's an original, shown some TLC. Guess it's just the perspective.

I added a piece of angle to the two bolts that hold the fuel tank guard in place. That allows the screwed rod to support the outer rear corner.

The tank straps are st stl and pick up some brackets on the new tank. I added some cups to the new tank, rubber lined, to sit against the original tank.

Had to get a 1/2" male NPT, to 1/4" female BSP socket, plus a 1/4" BSP male to female elbow. Then the 1/4" male BSP to 6mm push fit socket.

I'll tee in to the 6mm hose.

Question. Has anybody used brass compression fittings instead of the pushfits. Reckon they'd be more reliable. Will the 1/4" fit or must they be 6mm?

I have used compression fittings, don't recommend. They leak!

Push fittings are simple and easy to repair/diagnose.
