Perfect fit
Perfect fit and no leakage. Great price too.

Stopped the leaks
Caps stand a little proud because the o-rings are a bit thicker than the originals.
A**H
Not a universal fit
Bought for a 1972 Sea ray. 1.5" diameter is good but the thickness is almost double the stock O-ring causing my caps to sit proud.-Check the O-ring thickness before ordering
