I'm planning on installing connectors for airing tires. At the rear of the bus, there is an air chuck inlet at the bottom of the air dryer, and at the front there is an air chuck inlet at the small air tank under the driver's seat. Would those be good places to install air chucks for hose connections? I'd like to install one at the front and one at the rear for convenience. Any ideas on that?
That's a great idea as it is always a pain to drag a 50' hose around the bus from my compressor that is in the engine bay. keep us posted.
There should be a air connection on the passengers side rear door on the D's,you need to plumb close to compressor at the rear, my D had a connection at the auxiliary tank up front too but it had a 1 way check valve and was regulated and was useless except for a tow truck to connect.
The front one Glen is to release the air brakes like Clifford says for a tow truck. One in the rear I hook a hose to and leave it half way down in the bay ceiling with a tee and a hose going both ways with an NPT fitting on the ends. That way when I want to fill tires I just plug in a short 12 foot hose and can go to any tire to fill. :^
okj, I'm not clear. On factory MC8, is there an air outlet one can use to connect to for filling tires in the front? I know about the one in the rear passenger side and have used it to air up the bus.
Sounds like I need to stick with a long hose and one connection near the compressor. Too much regulating going on with the systems at the front. I'll take another look at it this weekend. Thanks everyone!
Don open tool bay under driver at front and look inside to the right just under the supply tank there should be a shradder valve there. Like a tire fill valve. There might be a check valve though on that one because that is for a tow truck to hook to so they can release the air brakes to move it.
I put a tee in the rear off the fitting that is already there. Ran a line to the middle of the bay #1 and teed off to each side with an NPT fitting at the ends that I can hook to.

I always ran the same pressure in all eight tires so I had a preset regulator at the rear and used a clamp on air chuck and never worried about the pressure and didn't need to stand and keep checking the pressure on each tire

Great idea luvrbus! Thanks for that!

Great idea luvrbus! Thanks for that!
You can always add a gauge at the regulator if you are one that uses different setting on other axles, I set mine and forgot about it,checking tire pressure on a bus is time consuming
Good idea thanks. Ya I have to stop when doing it because it hurts my thumb, lol :^
Great idea. I have a regulator I can put with the air hose and a clip-on air chuck.

You're putting in to much air? Lol :^ ;D
I don't run my engine here at the shop for airing my tires, I plug the rv into shop air but still use the same hookup on the RV just a different air supply to keep from burning fuel
Clifford's suggestion is great when one pressure is desired. From the recent discussion on tire pressure, it seems there are three different pressures required to properly inflate tires: steers, drives, and tag. Each carries a different weight so three different pressures.
TPMS is your friend in that it lessens the frequency of the need to have to check tire pressures.

Bus conversion people are about the only one's that follow those guidelines commercial people air a tire up to 10 to 15 lbs under max inflation and go,I can see a trucker changing their air pressures on 18 tires ,? do you weigh your automobile front and rear
ha! I.just mentioned what the chit-chat is about tire pressure. Only thing I am changing is lowering pressure all around to 85-90 and done. The TPMS is my friend while on the road. What I found interesting is the discussion did not get into how much the pressure changes while driving and which direction the sun is shining.

They are ugly on a bus but the Mexican buses have a self airing system that keeps the tires at a preset pressure ,the miliatry Humvee's use the same type system.You see a lot of truck and buses with the system to keep the duals with equal pressure the down fall of those if one tire goes flat both tires are flat in a few minutes.My TPM was a tied to the Silverleaf when it checked the pressure in the mornings if a tire was flat it won't let you engage the Allison to move that only happen to me 1 time lol only after 2 hours and reading the manual as last resort did I figure it out
