A 26 gallon compressor is pretty small to try to blast with.
CFM of the pump is more important than how many gallons the tank is.
I have the HF cabinet & a 80 gal / 7.5hp / 32cfm compressor and even that runs a lot.
I would recommend buying a different Jack.
I bought the arcan 35 new from northern tool a couple years ago & my 30 year old craftsman Jack works 100% better
