VIAIR Leader Hoses....answers needed.

damn that sucks man, i just ordered the 480 dual pack this week and they should be here monday. i guess i will be installing an extra check valve. i will keep you posted if i have any problems.

i replaced both of mine a couple years ago, luckily i caught it within a couple days and didnt fry the comp. i thought it was something i did, and didnt even call viair. just had new, beefier ones made. guess i should have bitched about it.

I fried 2 450's last year because of bad check valves, so I tossed em and put an edc on.

i know this is off topic but im in the process of doin air ride on my civic and i just wonder if havein 2 380s is overkill?

I just bought the dual 480s installed one and the crimp on the end of the check valve came off. I drilled it out didnt think about it leaking back through the head. I guess i will call viar to see if i can get a new one.

I wonder if its the heat that ruins the check valves? Maybe running longer leader hoses or cool tubes will save the valves.

I run across bad check valves all the time. I'm wondering if thats what causes Air zeniths to blow out as well. I have had to send my AZ back twice because the motor shaft coming into the crankcase just breaks in half. Both times I was able to blow back through the check valve. I finally said screw it and got a couple viars. I guess I should check and see If I got the new hoses on them.

I guess the best thing for everyone to do to avoid these problems is run reliable external check valves.

@ sema i spoke with lance at viair i asked him about similar problems he said to make sure the check valves are verticla if they are horizontal they will collect moisture and destroy the check valve (have been dealing with him for a while and no problems with him at all just great service)

The 480 i hooked up was brand new. I had a leak at the leader hose at the tank so i took it loose and the springs fell out the check valve. So it was bad straight out of the box. I ran 2 380s for about 3 years with no problems at all.

All I did was remove the hose from the head, put a water trap, then reconnect their hose.

Knock wood, no problem yet.

man I think you and lance got it backwards. The Check valves should be HORIZONTAL because if its vertical, the moister would just sit on top of the check valve, eventually corroding it and ruining the seal on it. I've had mine horizontal for 2 1/2 years on a 380 and no problems, but when I put on vertical, it blew. Think about it, it makes more since to put the check valve horizontal, how would moister be able to sit on the valve sideways it cant
