No I haven't tried that way. Maybe I'm burned out in thinking. But why would I get pressure with short hose right off of pump if it was bad? It pulsates without trigger pulled but when I pull trigger it is steady. That's the part that is throwing me off..I just don't have pressure when the...

Went to attic took line off of manifold where all tubing ties in. Hooked gun up there before manifold and had pressure Took manifold down removed all 5 check valves and found one of them missing stop..replaced. Though for sure it was going to work... Nope still no pressure!!! Calling it a day.

No soapy water in tank. All other bays are fine. I hooked water line to bay to air compressor and got plent of air out so don't seem like there is a blockage. If my valves were bad in pump why would I get pressure if I use shirt hose but not when I run the entire length to the bay. And there are...

This is what I tried so far. Removed each connection in Bay Area. At gun at bottom of boom at top of boom and still no change in pressure. I again remove main line that runs in attic to the bay... I remove it from pump and connect short hose with gun and have 800 psi when squeezing. The hose...

Neither. No pressure at bay or on gage. Gage works..I take outlet hose off replace with short hose and have pressure.

ok but i have no pressure what so ever when i connect the hose that goes all the way out to the bay..but if i hook up short hose with gun I have pressure.

Ok i dont want to sound repetitive but i am having same issue..well kind of. One day I all of a sudden lost pressure on one of my self service bays. I removed head checked valves and seals etc. I then hooked up small hose with gun and I do have more pressure..it was pulsating quite a bit but...

Thanks! I will check into that..I believe without looking at it and it being EARLY in the AM i have one treadle for under car and one for back-up. I believe my STOP is on the ramped sensor that also activates the "thank you please exit" relay and opens the back door. I have not been doing...

ok went back in today and the relay is saying the treadle switch is back off.. I have read your comments where this is a sign of failure and I have a couple of them on the way..Thanks

Sorry must of been one of those days where you overlook things when trying to accomplish 30 things in a short time. I got my second wind went back to the controller with my meter and found power going in the one side of the fuse holder but not the other. Pulled it out opened small little...

This is on a Futura. I have no horn. They operate off of a relay for each function. Drive forward..back up..please exit..and stop. I can force on each light from controller except stop. I switched relays around still not working. Have voltage inside controller but not getting light? Wire broke...

ok here is my question..i am having trouble getting stop light to turn on.. i changed bulb ok..can overide relay and try to force it on but still nothing..i have voltage to the light but nothing..i pulled the socket out tested in a outlet..light comes on.. im lost??? the drive forward slowly...

wow great info..see this a few times myself lately but i also have a different question. My under car spray on one bay isnt working..i check the plc and the number designated for the treadle switch stays on. Do these get stuck when they fail? It is just a normal flat 5"x17" treadle switch. I...

ok whats the secret to these 307 pumps? I have a couple that keep locking up and wont do anything. One day it will be working the next day they dont cycle. what is recommened air pressure also for foam brush and engine/tire cleaner. Please help! I just ordered new pump for shelf but want to...

Thanks for all the help! Yes it was blown head gasket. We have put another temp small compressor in its place while I am waiting on parts and have also dug into the bigger one that the previous owner was using as storage. Going to get both up and running and think I will be in good shape...

Ok thanks I will look into this. Yes other compressor has motor and compressor on top but motor not wired. It is working hard getting hot and tripping manual overload push button on motor. And this small town don't have a grainger but have a small pop shop I can try. Thanks for info. Is a...

Ok there is also another compressor that Is not hooked up next to this one that is piped together for storage I assume? Not sure what's wrong with it but is this a common practice? If one dies then pipe a new one into it? The compressor looks new but when I came on board it had a lot of water/...

Also air seemed to be leaking from top of compressor head when running?

It is A Kolbalt 3.7 running HP 155 max PSI 60 gallon tank. Noise coming from compressor side. It looks fairly new. Here is a link of a new one. http://www.lowes.com/pd_221565-14989-LLA3706056_5003702__?productId=3115863&
