I bought the Masterflow MF-1050(tsusami) last night, I'm mounting it on the rear RollBar & using my 25' hose with my hand held quick inflater and psi gauge on it.(using no air tank with it)>(Getting rid of that big red tank I have now..................... These Portable Air system can't be run completely blocked, so I need to incorporate some sort of "Adjustable Relief Valve" that release's around 50psi or so. Has any one plumbed in one of these or have the knowledge to point me in the right direction. Maybe remove the PSI Gauge & put some sort of Relief Valve there,, like in my picture.

50psi is pretty low. Most air compressors run 125-150psi.

Any rate the one above is from Poly Performance andcan be installed inline using a threaded "T". ;)

Thx Michael,...I'll remove the Gauge & install a "T" right there tonight. The reason for a lower Saftey Release Valve is the Pump will go sky high pretty quick unless I'm actually on the tire with the handle pulled. I want it to go up to around 70 & blow open so I don't smoke this pump while I'm airing up. An adjustable one would be perfect, I'll contact them & see if they come in different PSI ratings..

I've got the same compressor mounted in my current truck and will get a new one for my JK when it comes. I used a similar pop-off valve. If you're interested you can read the post here (http://www.hummerxclub.com/forum/viewtopic.php?f=29&t=3195&st=0&sk=t&sd=a&start=45#p87092)

Ipe, I want to thank you much,..I went to the site you directed me to & I followed your post to the letter. I went ahead & went with the open
New clip-on chuck that is a flow through, open design. Works perfect.
No need for a Pop-Off now. I'm thinking about getting an inline "T" & put it right below the clip on chuck, then add a PSI Gauge that I have right here. This way I can get a feel for what psi reading I'm getting. And you aso inspired me to mount it in the engine bay instead of the rear Roll Bar , you are spot on when you said the shorter the wire's going to the battery the better/stronger current.
Again, Thx, and some awesome Hummers over at your other Site.

Jim, i'm interested to see where you finally put the compressor. i have the same one and was thinking of putting it somewhere under the hood. be sure to post pics when you're done.

You bet I will,...I'll be on this tomorrow & should have something figured out. Once I mount it, then I'll run a few air down / air up test(clock times)>> from 14lb to 34lb. I'll take enough pic's to show it all.

i've done the timing thing. its pretty close to what they're saying on the hummer site, about 3-4 mins for a 33. also, are you going to hard wire it to the battery or the fuse panel?

I'll be going straight to Battery(hard wire),... I did read somewhere the 3 Min time to airup...that's more than fast enough.

No worries. I'm happy to help out :D

For a $50 compressor plus a few dollars in hardware & fittings it really is a great compressor. :smokin:
I think that you will be happier not having it in the passenger compartment. Its a noisy lil sucker when its running and come wintertime in New England and PA... well, your passengers (wife/kids, etc.) will thank you for not having it inside.

One thing to consider when engine compartment mounting is the heat issue. When the compressor overheats it will shut itself off for 15 minutes. When I had it loose this never happened. At the end of a trail, with it in the engine bay I can get only 3, 35" tires filled to 37psi before it takes a nap. :shaking: Perhaps in the JK this won't be an issue. I donno.

Oh, BTW, thanks for the awesome Hummer comment. The folks over at HXC are all serious wheelers and they really push the limits in their trucks. Bling is NOT popular over there. :laughing: When I get my JK I'll still be active with HXC and intend to be stopping in at Rausch Creek often. Maybe we will meet up some time.:)

Ya, I'm going to try my best for a good engine bay install, I'll be working on this after work today, but man did get cold in Pa. winter has arrived.
And you no a JK is way Cooler than an H3, so my Compressor won't overheat..:DYou have a great day........:beer:
See at Rausch someday.

Ok, for the life of me I couldn't find a spot to mount under the hood other than trying to relocate something. So, back to the rear of the jk I went, so I found a perfect place. Pictures below will show how well it all fits in the cubby hole. Poked a little hole through the carpet & ran wires to the battery(under vehicle). The pump will be dry at all times, I just lift the lid, start the pump, & go to it. The open chuck lets the air flow out so pump doesn't work at all, and you can move around to all four tires without a worry.

Below you'll see the contraption I made when I cut the mechanism off the factory hose & made an air down tool. Used an "Open Chuck" on new Hose Works Great(with PSI) gauge)http://img.photobucket.com/albums/v647/nam676869/DSCF0007-9.jpg

i have the same compressor. Got it for 30 something at Cosco.

I have been trying to figure where to mount it. That cubby hole in the back holds my straps and such so not there. I also would want to lay it on the carpet. THe top portion gets extremely (like will burn you if you touch it) when airing up. Especially after you air up 4 35" tires from 18 to 32 PSI

I paid 59.99 at PepBoy's:pissed: I could of bought one for my Son.:bawling:
Thx, I'll check the heat issue, if so, I stand it upright when airing up with head in the normal position. I also had that cubby hole filled with everything, I got a zip carry bag & it all went in there.
You have this exact one?

yeah Jim, costco has that for $50. that's where i got mine about 7 months ago. $30 would be an even sweeter deal.

I'm climbing under my JK tomorrow & studying all the extra space, thinking about taking one more step,>VIAIR 91025 2-1/2 Gallon Air Tank
measures 6"X24", maybe along the frame somewhere. Space is at a premium under there. Or just move the D@m muffler.

how does that pump compare to the Viar 450c? I have one in my ZJ with a 2 gallon tank. I had actually thought of removing it and putting it in my JK... but i'll probably get another one.

Never owned the Viar 450 but I think all these little pumps work about the same, I also think that an air tank working with these pumps would be better.

did it come with a black carry bag? I dont remember the box but mine had a black carry bag that i keep it all in a looks exactly the same. I think it was really $39.99 at Cosco. My dad bought it because he is an impulse buyer but when my mother found out she got a little and suddenly per my father it was a gift for me.... but hey whatever, ill take what i can get.

Yep, black carry bag came with it, I paid 59.99 at PeP Boys......

so how is your set up doing? I like the compressor but for some reason the PSI gauge is WAY off. When i plug it in to air back up it reads my tires at like 45 PSI and they are really around 18

I don't use my gauge on the pump, because it's mounted in the back of my Jeep, I just leave it on tire around 2 1/2 minutes & check with my hand gauge. I've heard that their gauge is off from others.
