Husky 26 gallon air compressor runs but will not pump air in tank

Replace the pressure switch

gary, i have the same tank same problem.. i havent replaced any parts yet... have you found a resolution to this issue?

Yes it has no oil. and you need to remove the top cover and check for air leak between the pump an the tank. if you have a large leak the tank will not fill. Two screws and the cover should snap off. check copper line for blown seals.

Did you trip the reset button? It should be there someplace i a spot where you can't see it, just push it till it clicks, make sure the switch is on. Hope this helps.

This can be a tricky dominoe affect depending whats in the way when you make a complete revolution while turning. Take everything off. If possible screw the pipe into the regulator first, then the pipe and regulator into the tank. If you are not getting the desired postion or alignment when you tighten it, then you will need to apply a few layers of teflon around the thread to achieve proper location.

clean fuel tank, and lines. just do a standard tune up. check every componet for wear or rust.

First check the check valve and also if it has an unloader valve make sure it is closing.

The main check valve is often right where the air goes into the tank. The unloader can be integral to the pressure switch or on the compressor.

Possibly the pressure switch needs to be adjusted to reach a higher pressure. Trace the power cord into a box that also is piped into the pressure line from the compressor. If the pressure works itself back down again, use thread-locker fluid on the adjustment screw to hold it's setting.

do you drain the water from the tank if not try it

Problem: My compressor is not producing the air that it once did. It takes twice as long to pump up.
Solution:
1)Turn off your compressor or disconnect the power.
2)Remove the connector tube that sends air to the tank.
3)Remove the head bolts on top of the pump.
4)Remove the head off of your pump.
5)Remove the valve plate off of your pump. It may be a one piece or a 2 piece design.
6)Inspect the valve plate for broken reed valves or broken gaskets above or below the valve plate.
