Celebrate the difference between making it and breaking it with our 1937 Harley- Davidson oil pump diagram t shirt. If you thinking pumping oil today is tricky, try doing that shit in 1937! This one is a tribute to the people who taught us, the people who fought us, and the people who got us here.
It comes in sizes small – extra large and features a pre-war Harley motorcycle oil pump diagram that we’ve adapted for print. The design is printed in breathable orange ink and the shirt is made from a 60/40 cotton blend fabric. It has an athletic fit so order up if you like your shirts baggy.
