FOUND!: GAS CAP (Or gas deck fill assembly) - 1978 Glastron Carlson CV23-Read on

[fireman24mn]

I had a marina loose mine off my CV-23 this year too. I am also in need of a gas cap

After extensive research and turning up negative results finding a replacement TEMPO gas cap (or Tempo deck fill assembly) for my 1978 Glastron Carlson CV23, I started the search for a whole new deck fill assembly. Be aware there are a ton of different deck fills out there and I could not believe the multitude of differences. So measure accordingly. Here is what I found as the absolute closest match dimensionally (as far as c/c screw hole dimensions, flange width, overall length and fill hose size):

Purchased from here: https://www.summitracing.com/parts/edm-265-25

Although I wished I could have found the original tabbed gas cap and/or deck fill assembly with the splash guard, this Eddie Marine unit fit perfectly and the quality is excellent. See the attached pictures of finished installation.

Thank you all for your help!

I hope this thread helps someone else so they don't have to go through all the research.

I?ve used the ones from Overton?s a couple of times.. the M or N style.   It?s very close to original..
