Some thoughts and suggestions needed...

So I decided to save myself a couple hundred bucks and decided to just fabricate my own fuel tank for my 51 Plymouth Belvedere...What would you guys suggest using for a fuel sending unit and float? Not really sure where to look for these...Thanks!

 

Do they make universal units?

 

depends on what gauge you will be using , the sender has to match

 

Well I would like to use my stock guage pod...but the fuel tank and stuff were shot...but yeah I would like to use the original guages...

 

if you could find the ohm range of the factory gauge, you may find something that interchanges

 

Thanks guys I appreiciate it!...I will start from there!

 

Do you have O'Reilly auto parts in your area? If so, go there and buy a universal sending unit with matching gauge. They are CHEAP and work fine. I can't vouch for how long they last, so I recommend putting a hatch in your trunk floor to allow you to remove the sending unit without pulling the gas tank out of the car. (Actually, I recommend doing that no matter what. Makes life SO much easier.)

Several years ago I used that setup in a '50 Ford. The arm was adjustable on the sending unit float. The gauge was generic, black face with white numbers and pointer. It even came with a bracket to mount the gauge under your dash if desired. I think the whole setup was maybe $25.

If you don't have O'Reilly's there, call around and try NAPA or Autozone.

 

measure the resistance with the float all the way down, then all the way up.
then check a stewart warner and other sending unites until you find one that matches.

 

The float and your fuel gage has to have matching Ohms or they won't work plus you have to consider the 12v & 6 v difference also . There are no universal floats except a stick with makes on it !

How certain are you that this will work with my original guages and that this is the right ohms...I have yet to find out what the suggested ohms are from stock...

 

that fuel sender from Amazon has a range of 33-240 ohms , that is what a Stewart Warner gauge used.....i don't know if that will work with a `51 Plymouth fuel gauge.

you must find out what ohms range your existing gauge needs to operate properly. then you get the correct sender.....that is how it is done

as for 6 or 12 volt.....that won't make any difference. if you are converting your car from 6 to 12 , you put the voltage reducer on the power supply for the gauge

 

i believe that maybe your gauge needs a sender 73 full and 0 empty....but don't hold me to that. certainly someone here knows for sure
