1959 to 1970 gas tank

[John ED Renstrom]

we are looking for a tank for this 1958 here. today we took one off a standard 1958 caddy. got it home and of course it will not fit a 1958 CC car. that one is the same as the standard 1957 caddy. but how ever I did get to compare this tank off of a 1958 with the other tanks around here. Paul was able to look up some numbers in his old parts book. the standard tank off a 1958 caddy is the same as the CC tank from 1959 to 1970. so (Mike) or any one looking for a gas tank for there 1959 to 1970 Commercial chassis car can buy a new or used 1958 caddy tank and put it right on. the fuel gage is the same as the standard 1958 caddy also so that chapter in our parts hunting is over with. now anyone have a good 1957 caddy gas tank??

My original tank was lost during restoration. Somehow replaced with standard/modified tank. Would like to have correct CC tank. By the way, I went to refuel my 64 which was on empty and when i took the gas cap off, there was so much pressure that it blew the dang cap halfway across the lot. It is a non-vented cap because I guess I have a hole someplace else to let out the air. Is is suppose to have that kind of pressure???

so all you need to find is a 58 caddy to donate the tank for your car. I have some information that they will be re poping one in about 45 days. but if it's like the 57 they will be priced around 500 bucks. a lot of money. you need a vented cap for the car. summer get here you going to have trouble along with it quiting on you as you drive it. the 63 was not a closed system

John I have a 57 tank, I built a custom tank for my eldo, I could take some pictures in a day or so if it would help or you can give me a call at 573-757-7432.

My gas tank solution - sort of

A bunch of years back when gas was below $2.50 a gallon and I was running around the country willy-nilly, I got tired of stopping to gas up my 1964 Cad MM. My fix was to take a spare '64 Cad de Ville tank, position it between the floor and original tank with felt spacers and hook them up with what some would call Rube Goldberg piping. I now have 43+ gallon capacity at fill-up. I also have an electric tank switchover under the hood with an under0-dash control.
To keep track of my available fuel, I only use the de ville tank sending unit. I fill the tanks, run off the top tank (de ville) until I start to run out, then switch over to the bottom tank (coach). As I am drawing from the bottom tank, fuel is returning to the top tank via the '64 Cad A/C glass bowl fuel filter vapor return line. As the fuel returns to the top tank, the gas gauge is activated. By the time the bottom tank runs out, I know how much fuel I have left and arrange to fill up accordingly. This has been working for me with no problems for at least 10 years. Needless to say that impromptu weekend drives in my coach to places like Tuscson or Vegas or S.F. from here outside Bakersfield CA are few and far between.

Thats just super cool. A spare gas tank. I may have to do that to mine.

Two gas tanks may make it go longer but it will cost you twice as much to full it up, so it still costs the same for the same distance traveled.
