my first mazda

so i traded my street bike for this mazda, i love it, but im not to familiar with bagged anything, its a pretty nice truck, needs work, but thats why i like it, i can do what i want with it. but anyway, the driver rear bag leaks slowly, i think its the valve, so i was wondering what that would cost, and the passanger side when i was driving it home, the rear popped a line, so i rigged it to drive and now am wondering what i can do to fix that, its the line that fills the bag that popped, i just dont know what kind of line or anything, being as the line that was on it obviously didnt work. any help would be awesome, and if your in the phoenix area, some beers at my place if you can come look and let me know your opinion on the whole set up. thanks. pics are in my garage. thanks again

nice looking truck man.

if you want to find out where your leaks are coming from get a spray bottle and put a bit of hand soap in it, fill the rest of the bottle with water, then air up your truck all the way and spray every fitting you see with the soapy water.
and wherever you have a leak youll start to see soap bubbles.

as far as the line, if it just popped out of the fitting you can cut the line down an inch or so with a sharp blade then rough it up lightly with a coarse sand paper and shove it back in, shouldnt come back out.

make sure the airline is cut SQUARELY other wise it will leak again. never heard of roughing up the line b4 putting it in the fitting, but if that works for ya then cool.
truck looks clean BTW.
depending on the type of valve, they're around $30. i'd check to be sure thats what is leaking before just throwing a new valve on there tho... maybe you can pull the fittings out and re- teflon tape them and put them back in. or re-cut your airline if its leaking from there. or maybe depending on the valve you can carefully take it apart. there might be some moisture, or dirt in the diaphragm. you can carefully clean it and put it back together and try it. i'd do all those things before buying a new valve - just cuz its free to try to fix it.
