Questions: I recently purchased your 6 volt gauge 640763 for use in my '34 Ford. I now realize that my current new fuel sending unit has the wrong resistance range for this gauge. From your web site I have learned that this sending unit is recommended for tanks with 6 bolt holes. Before I throw more money on this project would you please tell me what bolt circle diameter does this unit have.

Questions: I am looking for a sending unit for a 1970 CJ5. The tank is under the drivers seat. It has a 12 volt system. Is this the part I need?
Question By: brad on Dec 10 2016 9:15 PM
Yes this would be correct for you if you are a 6 hole style tank or part number: 948696 if your lock tab style.

Questions: I have a 1946 CJ-2A. The underseat fuel tank has 6 holes instead of the 5 holes shown for a CJ-2A fuel sender. Will this one work?
Question By: Charles on Sep 1 2016 6:59 PM
That would be an unoriginal tank then in your CJ-2a. Please email firstname.lastname@example.org some pictures and we can help you ID what you need.

Questions: I have a 1957 Willys CJ5 - I recently bought a Omix-ADA speedometer from you for it that includes the temp and fuel gauges built in...will this sending unit work with the required specs to activate the gauge (ohms etc...) also i would assume that the single white wire that hooks up to the speedometer is all i need to ensure functionality right? I appreciate your assistance!
Question By: Anonymous on Nov 10 2014 12:00 AM
Yes they are compatible with one another. See 914845 part number for the wiring diagram. Yes just one wire goes to this sending unit.

Questions: Im confused on how to hook up, should the positive wire be hooked to the top of the sending unit to get it to read at the gauge or the negative wire. Thanks, Tim
Question By: Anonymous on Oct 3 2014 12:00 AM
You should have it connected to the 's' post on your gauge.

Questions: I have a 1967 Jeepster Convertible with the 225 V6. Several years ago, I replaced the fuel tank with one from a Commando from the same year. I believe the tanks are identical with the exception of one exterior mounting tab. Which sending unit, gasket, and return line do I need?

Questions: Have an M38A1 that has been converted to 12 volts, will this be an exact replacemnt the stock 24Volt fuel sender
Question By: peter on Jul 3 2012 12:00 AM
The M38A1 has a five hole sending unit. The one for the CJ-5 is a six hole sending unit. I would use part number: 640694 if you are 12 volt for a M38A1.
