67 fuel sending unit quality
 

Need to replace my sending unit. Changed that and tank 3 years ago.
Is there a certain quality I should look for. The sending units range from
$55 to $200. I purchased a new anderson tank and $180 unit 3 years ago. The unit is bad. Should I buy the one on Ebay for $55, $80 from Long Island Corvette or the $180 one.


Not looking forward to this job.....but I know we have all been there.

John Hinckley in his Corvette Enthusiast article on C-2 fuel systems mentions one made by Fargo Industries as one of the better quality repros.Corvette Central sells this for $80. :thumbs:

I don't know about long-term reliability of the CC Fargo unit, but it bench-tested very close to an original AC sending unit. :thumbs:

I've bought 2 units since February. Both had problems:

1) First I bought one from Corvette Central. Worked great for about 1 tank of gas, but then the wide, coated strap that is part of the sending unit shorted against the fuel pickup body because it was too close. The coating wore off and the unit shorted.

2) Next I bought one from Long Island Corvette Supply. Definitely a different unit than the CC one. After taking care to ensure no coated wires could short themselves out over time, I installed it and it leaked fuel at the wire terminals. Had to remove it and adjust it twice to get the terminals to stop leaking fuel.

So whatever unit you buy: Ensure none of the coated wires will rub against any metal parts, and verify the sender terminals are snugly installed with the press-nuts to ensure no leaks.

I have this AC Delco unit in my basement inventory but cannot attest to its accuracy or reliability as I have not tried it.

Only to give my personal experience based on a significant number of sending unit replacements (not mine), and having seen a number of "reproduction" units that are total crap I do, and would always, recommend in this case you pay the price to get a genuine AC/Delco replacement. :thumbs:
