Hi guys, I have a 1952 ford pickup and just installed a 68 mustang tank and sending unit. I was in need of some advise, on how connect the truck to the mustang sending unit. Thanks in advance
i am doing the same thing,just havent got that far.you might have to get 6v to 12v ,i think mine only has 1 wire,cant remember. tank has drain and pick up tube..you might have to install new fuel gauge?
The 52 ford has two prong sending unit and my mustang only has one prong, so any info will help. Thanks guys Posted using the Full Custom H.A.M.B. App!
Wire from Mustang sender prong goes to sender connection on gauge. Probably best to run a ground wire from one of Mustang sender attaching screws to frame (ground). Usually the fuel gauge gets a variable ground reading from the sender, so I do not agree with the diagram showing gauge needing a ground, unless to ground bulb.
Ford used 6 volt gauges up into the early 80's this is what they used to regulate the voltage to the gauges:http://www.ebay.com/itm/360928515943?_trksid=p2060778.m1438.l2649&ssPageName=STRK:MEBIDX:IT Check out this diagram.
Use a Ron Frances vr1 voltage reducer . One connection is Positive the other is ground . I have the same set up on my 48 and works fine Posted using the Full Custom H.A.M.B. App!
Good point on the gauge voltage regulator. Easy to find one for a 68 Mustang. Would attach to the ign prong on gauge. 12 switched power to it's input. Just so we don't confuse the original poster; The ground wire shown in Mustang diagram provides a separate ground to not only the gauge voltage regulator (which is very important to proper operation of the gauge), but the whole gauge cluster. That's how they can use metal dash light sockets and only need one wire for each. I think we all have found out that it is difficult to have too many grounds.
In order for the gauge to read proper you will have to match or make sure the ohm range for both the gauge and tank sender are the same. As I remember Ford senders pre 1987 will read zero ohms at empty and 73 ohms at full. Gauge Volt Reducer No need to rebuild gauges as you can install a gauge voltage reduction unit as found on ford trucks from late fifties into the early seventies. You can also use the original sending units. This unit installs between the gauges & the 12 volt hot wire. They can be found in about any salvage yard The voltage reducer can be found at Napa Auto Parts. Part # is IR-1 or Standard Ignition Parts # VRC-604. Cost is about $20.
The f1 trucks did not use a resistive type sending unit like the mustang. You need to replace the gauge with one that will work with the mustang type or replace the sender in the tank with one from an f1 truck. Probably easier to use the f1 sender and modify it to mount in the tank then use a runtz 12v to 6v reducer on the gauge itself.
Not wanting to disagree, but the mustang sending unit will work perfect with the ford truck gauge. I have done 3 this way and doing my sons 49. Never had a problem and dead on reading, just saying. Posted using the Full Custom H.A.M.B. App!
Thanks guys, getting the vr1 from Ron Francis . Thanks so much for all the great info Posted using the Full Custom H.A.M.B. App!
