Weird Gas Tank Problem
#31
#32
If thumping on the dash changes the gauge readings, or the gauges are doing the hoochy-coochy on their own tells me the CVR is going bad. The CVR = constant voltage regulator feeds a constant even flow of electicity to the gauges. Old age and corrosion affects these too. They've been a PITA for years. Only one type was used for all the 1961/66's. All the autoparts stores carry them, and they are fairly cheap. There are different types used for later yrs, so y'all might take the old one with you, or look at the type and number of the spade connectors used. The CVR is shaped like a small box, about 1" x 3/4" and mounts to the backside of the dash near the gauge cluster. One bolt holds it in place.

Be careful what you wish for . . .

Needless-to-say, I prefer my old trucks. (& I never have owned anything later than '68.)

They would not tell us what they did the second time, but they said there are SEVERAL valves in the filler tube! I cannot imagine what for: anti-siphon, anti-???, . . .

Bill, It is the wife's deal. First time she showed me the RO, second time it was fixed & she did not care. (I still am curious, but I am "out of the loop" on this deal.)
P.S.: I NEED to stay out of these deals - I might win the argument with the service writer, but it is not worth risking a stroke!
P.P.S.: I sure hope Tedster9 finds out his problem has a cheap fix. (mandatory tech content)

Interesting thread...and I too would love to know the answer to your last question Bill about the o2 sensor and what the dealer tried to do and failed with you...I know when I get repairs done at the dealer I wanna see the parts that came off and ask the tech questions as to this that and the other...
As for the fuel pickup/plugging issue...couldnt it also be a possibility that the line is dying internally and causing a blockage midstream in the pipe...blowing backwards may help a bit, but if its in bad shape and so on, more crap mighta created a dam in there...as for the line in the tank itself...I was thinking that it might have rotted off...arent the tanks used thru the 72 model yr as I recall from Hollanders...as for it dying on you and not starting...I would get a wood dowel and put down the neck and see what ya come up with for a fuel level...if you hit bottom ya might get an idea of the crud on the bottom too.
One thing I learned...kinda a PITA initially, but if you get a dowel and run it out add gas gallon by gallon, marking off where each gallon is on the dowel and a mark as to line up on the neck too so you get accurate readings...
Hope this helps you out some, cs65

Replaced the fuel tank itself last spring. $urprisingly the tank was in good shape with no corrosion or sediment, and the pickup tube was in excellent shape. The likely problem was the fuel pump, also replaced. Anybody needs a serviceable in-cab type fuel tank, I'm yer huckleberry.

I'm not familiar with this part, and when I googled it, it appears to slip over the bottom of the fuel sending unit???? My sending unit doesn't draw fuel, and I don't recall seeing any "sock" on the fuel line in there.
Please describe more.

If there was one, it's long gone.
