Re: [OMC-Boats] Carb and fuel gauge

My take on you CARB float parts-source problem:

Your auto parts store simply doesn't have access to the same suppliers
that the Rochester Carb (you do have a Roc-cha-cha 2GC, right?)
Rebuilders do.
So dump your local (not so smart) auto-parts sources and go global, man.

There are dozens and dozens of sources providing rebuilt Rochester "2-
Jet" (the 2G-series; 2GV, 2GC) carbs and parts. These carbs were used
on literally millions of GM-powered vehicles from 1955 - 1978, common
as dirt, really!
Remember the '55 Chevy which introduced the world to the small block
V-8? Or how about the Tri-Power Pontiac GTO? They can't rebuild
them without having a reliable source for new floats, duh! So you
just have to get smart, that's all.

Do a google search on Rochester 2 GC (or Rochester 2-Jet) and you'll
find what you need. The internet is indeed, your friend!

It took me about 30 seconds to find (I would hate to make a living
doing nothing but google searches for people):

http://www.carburetor.ca/carbs/floats/f10.htm

Also: http://www.carburetor.ca/carbs/tech/Rochester/TwoJet-index.html

Just order an "F10" float and be done with it.

There are probably many other sources, as well, so have at it. (And
BTW, the fuel gauge and sender is all very common, off-the-shelf,
"industry standard" (240-33 ohm) Stewart-Warner stuff.

Nothing special about the FUEL GAUGE wiring, sender or gauge (small 18
GA ORANGE was originally used, as very little current is passed from
sender to gauge.)
See my website http://hhscott.com/evinrude/images/wiring/68_v6_ALL_WIRE.jpg
    If you reading an OMC factory wiring diagram is helpful.
