The Cessna 120-140 Association Forum

Need to replace my fuel caps on my 1948 Cessna 140. Mine have two vent holes in the top of each is this right???

It is right! I bought some a while back. I’ll see if I can find the part number in the next day or so.

These fit nicely. I haven’t drilled another hole yet, but. it will be easy. Part number is 05-01058 from Aircraft Spruce. Picture is too large..

Here's the picture:

You need to read this posting in Neal Wright Technical Articles:

Mis-using gas caps on 140s that are meant for 140/120 planes

It will explain venting on each type of airplane and what type of gas cap you should use for each.
