The RV fuel caps must be tight so they do not leak. When they are tight enough not to leak, the handle is hard to lift up and requires some sort of pry bar. This handy fuel cap opener is .187 x 3/8 x 2 and fits easily on your key ring and opens your fuel caps with ease.
This fuel cap opener is constructed with a paint friendly high density polyethylene.
