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?

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 email@example.com 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: 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
