A Little Bit About The Stock Pump. It’s A Devilbiss (Part# D27983) Radial Two Piston Design. This Pump Is Made Out Of All Aluminum. The Two Piston Design Is Known For Noise And Vibration. The Devilbiss Pump Doesn’t Use Oil And This Is Why It Only Last For 50Hrs And Is Also Known As A Disposable Pump. They Do Still Sell Them But In The Long Run It’s Better To Upgrade To A Pump That Uses Oil And Has More Pistons To Lower The Noise And Vibration.

Does the replacement pump come with the fittings for the input hose and the high pressure hose? I cannot tell from the picture. Also, does the oil come with it. Thanks.

Yes this pump came with the fittings for the hose connection and the high pressure side. I am pretty sure this pump also came with oil. It doesn’t hurt to buy some just in case it doesn’t then you already have some when its time to change the pump oil.
