Q: Do the sending units and gauges have to match (ohms) or will they fit any gauge? The reason I’m asking is because I need both.

Q: What type and size screw do I use with fuel sending unit?
- A: Try a number 3 or 4 machine screw.
Q: What carrier will deliver my order?
- A: We typically use UPS or USPS depending on your preference.
Q: Are the resistances overall, empty, half and full? Is this a 5 hole mounting unit? Is the float compatible with today’s gasoline?
- A: 73E 10F just like original. It is a 5 hole mount just like original. Yes it is good to go on todays fuel.
Q: Does this unit come with new float?
- A: Yes that is correct.
Q: Do you have just the float bulb for sale? All the parts are there but there is a crack in the float.
- A: It’s part number: 17729.01
Q: Do these units fit a Mahindra CJ-3B?
- A: It should work ok as long as you are 5 hole.
Q: Do you have a gasket and gas tank sending unit that will fit my 1970 CJ-5 Jeep with the 225 engine?
- A: We do. Please call us toll free. We need to ask you a few questions about your CJ-5.
Q: I converted from 6 volt to 12 volt. Will my gas gauge work with a new sending unit that is for 12 volt?
- A: The sending unit works off resistance and works for either 6 or 12 volt. Your gauge in the dash needs to be either 6 or 12 volt depending on the voltage your are running. We sell both.
Q: Just bought a ’47 CJ-2A with this fuel sending unit (item #640694) the piece that screws into the top of the unit is missing. Do I need to replace the whole unit or is that top piece available?
- A: Sounds like you need a new float. This will do the trick.
Q: Is this sending unit a replacement to be installed in a 53 M38A1, that’s been converted to 12V? If not can you suggest another part number?
- A: Yes this will match up. On the M38A1 you may need to lengthen the arm if you want it to read accurate.
Q: Where does the wire hook on that sends the fuel level to fuel gauge on a 1946 Willys CJ-2A?
- A: It goes from the sending unit in the tank to the ‘s’ post on the back of the gauge.
Q: My restoration project is a 1952 M38. It was converted to 12 volt a long time ago. I have been told that this sending unit will work with the M38 fuel tank. Will the arm have to be lengthened and, if so, how long should it be?
- A: Yes this will be the correct one for you. You can lengthen the arm if you like for that tank but really it will read empty and you will still have some fuel left with is good.
Q: I have a 1952 M38 which has been converted or was already 12 volt. Being a military Jeep I need a new sending unit for tank and wonder if I need to purchase new gauge and sending unit? Do you offer this kit?
- A: This will be the one for you and bolt right in. You gauge will need to be replaced as well.
Q: My 1950 restored Willys Jeepster fuel gauge reads one half only when gas tank is full. Car is 6 volt system. I have a vintage wood boat whose gas gauge does the same thing and it is six volts also. What is the explanation?
- A: You may need to adjust your fuel tank sending unit and check it with a ohm’s reader.
