That's a whole lotta shiny new in that 35 year old truck. You'd better hurry and get it dirty so it matches everything else.

Thanks Matt! I'm still not sure how to properly copy the url over, but I used yours and it works fine!

I have a leak at my pressure gauge, but other than that, all systems appear to be nominal. I'll post some pictures, and maybe a video, later.
Glad you got it going! That's about a normal time to fill a tire from most sources. Think about how tiny the actual hole in the valve stem is! On my 40 I have dual stems. The second stems are Monster valves. They will air the 40's down from 25 (street pressure) to 4# in about 20 seconds. They will air back up the tire in about 45 seconds! CO2 seems to air up quicker too than OBA. I think it's probably because of the dry gas.

....looking for a web pic I found this article....pretty much sums it up...

Cool, yeah I can see that especially for larger tires, having a less restrictive valve would help. CO2 also has the advantage of all of its pressure potential available to quickly inflate the tire. Same with an air receiver. I need to start thinking about where to put one of those now...

Sweet you got it going! Put a brick on that gas pedal for faster performance... right around 1200 is a good sweet spot IMO, 2000 is the upper limit. An ice scraper between the pedal and driver seat can make for a good hand throttle.

I just have to add this: I don't know why it takes me so long to do stuff like this - I looked over Marco's thread and he installed his in an afternoon. Mine took me two weeks +/-

Oh well. It's just the way I am I guess.

You could have brought it over to my place and it would still have been in pieces this fall so I'd say you did good

Took Jeff's welting and made some cuts so it could make the bend. We'll see what happens here. I might have to come up with some sort of hold-down so the pipe doesn't bounce out of the slot. It's ugly for now but if the theory works I'll clean it up some.
