MotoXcycle MXC 5” Round Tank with Spin-On Filter Compartment for 1999 and Under Harley-Davidson Softails

This beautiful hand crafted 5” round aircraft aluminum oil tank features a compartment to accept a spin-on oil filter and a battery box.  

The inlet/outlet group is comprised of bungs welded to the tank. The feed bung is internally raised to prevent contaminants from entering into the oil delivery system, the vent bung has an internal tube that goes to the top wall of the tank and a return bung that feeds the oil to the oil filter. The drain bung found towards the rear of the inlet/outlet group and at the very bottom of the tank is internally tapered to ensure all of the oil and any residue can be completely drained from the oil tank. 

Technical specifications:
Tank width: 12.25"

Tank diameter: 5"

Inlet/Outlet group location:  35 degrees up from lowest point.  When the tank is installed on the bike, starting from the throttle side the bung sequence is Feed, Vent, Return.  The Drain bung is at 0 degrees and is the bung closest to the rear of the bike. All inlet/Outlets (bungs) are machined to accept 1/4NPT fittings. Return bung has an internal line that brings the oil to the far left of the tank to give the oil time to mix before returning to the feed bung. The Vent bung has an internal line that provides venting close to the internal ceiling of the tank.
