Leaky air bag set up - The 1947 - Present Chevrolet & GMC Truck Message Board Network

jlipman · 03-08-2017, 10:22 PM

I'm finally at the point in breathing life back into my truck that sat for 10 years where the big stuff is done. Now I need to chase the leaks in my air bag set up. I used the kids bubbles mix to spray the lines but seeing the bags is not so easy. Has anyone tried putting push connect valves in line to isolate areas to narrow the area to search? I think they are leaking out if the fittings in the bags.

I had a bagged S10 for quite a while. It sat for the better part of 2 years while i was in Japan and then a year again while deployed to Afghanistan. It was real leaky when i got back to driving it. If i was you, id replace all the air lines. Then see what it does. I ended up rebuilding all my valves too, never had a leak again up til me selling the truck. The valves are easy to rebuild

Just my two cents worth. Adding components also adds potential leaks.

I would only put the valves in to isolate the leaks then remove them. I'm going to give it a go. Then I can isolate the valves and the bags in an organized way. I'll let you know if goes.

I use 'push-in' fittings all the time in designing, building and troubleshooting industrial/automation pneumatic (air) systems.
If I want to isolate an area or a device or a line, I simply take the hose off the device and bend it back 180° and temporarily put a tie wrap on it.
Despite how this sounds, it works great, it's quick, it doesn't leak and the quality of hose that I use on my projects (SMC/FESTO) suffers no degradation from this....and again, its fast.
You just have to 'get good' on how to remove the hose from a push-in fitting...which requires you pushing the hose 'in', the pushing the fitting lip in...the pulling the hose back out again.
Here is a quick pic of one of my typical (partial) installations
My two bits.
