Questtion 1 is: I have oil pressure gauge (aftermarket of unknown brand) that looks like it has a threaded male fitting on it, but my sending unit on the oil filter base is electric. What can I do if anything to use the gauge that I have? Looks like it reads off of some pressure sending method obviously not electrical. Question 2: My "ammeter" or "charging gauge" is not connected: anyone know what wire(s) I need to find behind the dash? Question 3: is there a place to buy reproduction correct gauges that anyone knows about? I have a non Custom Cab 66 f100 4x4 .Thanks in advance...

 

The oil guage you have is mechanical. It requires a connection between the guage and the engine. Optional CC Guages were electrical.

The ampmeter is also electrical driven. there are two types an inductive one that reads current through use of a hoop that the main power feed goes through or one that has a direct connection.

Each of the optional guages require a stand alone harness.

can you post the guage numbers for the oil amd ampmeter? NOS is pretty pricey.

Also post the stand alone harness number. Have not found any source for them.

Questtion 1 is:
Sounds like a mechanical gauge which uses tubing instead of wire, you could switch the sending unit on the engine for a fitting and use the gauge.

Question 2:
I have been told that this things are dangerous and should be replaced with more modern voltmeters

Question 3:
Anyone of the vendors mentioned here should carry gauges

 

Sould be able to remove electric sending unit, may need an adapter, purchase 2-3 feet of flex tubing, compression fittings, and should'nt take much time to hook up. Occasionally see the gauges on ebay, few members have indicated they switched to aftermarket gauges perhaps they can provide sources. Have seen them in number of the FTE sponsored Ford parts suppliers. I purchased couple of extra instrument clusters on ebay, confirmed with seller the gauges worked and purchased at reasonable price.

Had simular issue installing amp on 65 F100, ran all the wires to gauge but came to mental block, despite all the instructions from other members, then a member, hiball, emailed a drawing of the connections for under the hood and it became perfectly clear, matter of moving 1 main wire from one location to another and installing a junction/fuse block. Anyhow, works great, kept the idiot light, although,prefer amp gauge because lets you know of an electrical problem in advance, with idiot light it's usually too late. Posted page on the 64 truck diag. hopefully it will be of some help, and perhaps other members can provide additional info.

I added the stock optional Custom Cab gauges to mine. You can too, with a sweep speedo and gauge cluster sourced from Ebay or other used supplier. Having the additional harness for the extra gauges makes it much easier, but it is not essential (you can make your own).

I did not use the AMP gauge...I installed it for looks, but do not want the fire hazard. The OIL gauge is electrical, so you need the sending unit for a gauge (still available) and a brass fitting to allow both the new sender and the original one for the light to be used. There is plenty of room to install both on the FE, if that's what you have.

The aftermarket gauge you have is a mechanical unit and would require a similar adapter to retain the light sender, but instead relies on a small orifice oil line run from the engine to the gauge. Use a braided steel line, not a plastic one for this. Autometer and others sell kits for this. The electric ones are probably cheaper to install once you figure the lines and fittings and are certainly easier. Electric sending units must match the gauge, however, so if you use an Autometer gauge you need to use their sender.

The OE gauges are not reproduced. They are not terribly hard to find but the price may be prohibitive, and you may just want to consider two aftermarket gauges instead. This give you a lot more flexibility on cost as well as appearance. They can be installed in the non-CC dash panel by opening up holes either side of the speedo. So long as the gauges match they usually look ok.

 

I replaced the little black hose on my oil gauge with one of the braided stainless ones and let me tell you that is one expensive hose but I dont think this one will blow.
Another advice I was given dont know if its true or not is that you are supposed to run your mechanical sending lines (oil-water) by themselves because of the heat they produce if you run them along with wires it could fry them. Anyone know if this is true?

 

did ford make a stock tacometer? i've seen aftermarket ones before but stock usually looks better

 

Ford offered accessory tachometers "for all vehicles" that mounted on the steering column. There were at least 8 different versions. The earliest versions were marked Rotunda from the mid 1960's. Both a 6 and 8,000 RPM version was offered. After 1965, there were more versions. Some were plain, some had crossed checkered flags. Then there were the Rally-Pacs which had a tach and a clock. These were offered for Mustangs, and other cars, but dealers would install them in a truck, if the customer wanted one.

 

i dont think ive seen one on the column before. the ones ive seen have been bolted to the bottom of the dash or in the dash insert next to the speedo. do you know of a link where i could look at some of them? i would like to have one. as long as i'm talking i have the original 240-6, t18, and 9" for a drive train. what are safe top speeds to run with her? i can only tell so much by ear, and i don't want to screw up my truck. heres what ive been running 1st-3mph 2nd-12mph 3rd-25mph 4th-60mph tops. good bad ugly? ive been told my 6 will last forever if i dont abuse it so any suggestions?

 

Sorry no links...that tach info was from memory. Your best bet is find some car accessory brochures from the time frame (1962/72) = faxonautolit.com is one place that sells them. For Rally-Pacs, find a 1965/66 Mustang forum...there should be pics there.

 

Had same set up on 65 F100 until installing small V8. Purchased truck in early 70's and can count the number of times I have used 1st gear on one hand, rarely used, basically a 3 speed. Have another 65 with 3 on the column and prefer the T18. Don't have a tach, pretty much go by feel, the speeds noted is about the same gear to speed ratio I use less the 1st gear. Find 60-65 mph on freeway is about the limits I feel comfortable at, have gone to 70-75 mph but sense power trane is under stress. Perhaps more knowledgeable member can break it down, mph to tach ratio.

The vintage Rotunda tachs go for BIG money. Trust me, I've looked. I ended up doing what everyone else does; put a crappy Sun tach on the column. I tried buying some vintage tachs, but both I bought didn't work. Waste of money.
I find that the engines of that vintage make such a clatter long before you get near redline you won't ever approach it.

 

i start in second i hardly ever use first gear to

which tach do you think would look the most origanal?

 

Just couple of examples, but here are couple, one installed on column, and the other on in cluster.
