You guys are kidding, right?

Bill, you say it is ridiculous to say having the tank inside the cab is more dangerous? So if you knew you were going to have a bad accident today and had (2) identical trucks, one with a gas tank in the cab and one wiht the tank mounted in the rear between the frame rails, you would jump in the truck with the gas tank inside the cab instead?

"1965 Chevy C10", it isn't "the back of the cab buckling" that is a concern. If you get hit from the side by any vehicle with a high profile, like an SUV or truck, there is nothing but sheet metal to take the impact. If the gas tank ruptures you are sitting in an enclosed area with gasoline and gasoline vapors.

You say you prefer that? That is actually what you want? Compared to having the gas tank outside the cab, where if it does rupture, you are in an enclosed area away from the gasoline and gasoline fumes?

Hey, I love these old trucks but there are aspects of them that can be improved. They were built before the strict safety standards and testing that are required today. They require crash testing now, they didn't back when these trucks were designed. How many vehicles are built today with fuel tanks inside the passenger compartments? The reason gas tanks are now put between the frame rails of vehicles is safety.

I am all for personal choice. If you want to keep your truck all original, including the cab mounted fuel tank, that is certainly your option.

I for one want to be as far away from the fuel tank as possible in an accident. Not sitting in an enclosed area with it. But that's just me I guess?

Ralph Nader and all of those safety freaks also got caught staging alot of those "explosions" and so-called problems. A full tank of gas can get nailed by a train and not explode, it's the vapors that blow. The cab mounted tanks are vented! If you feel it's a hazzard, move it. I still can't remember ever hearing of any problems from cab tanks and they've been around for a hundred years.
Good luck with keeping the external tank safe! I've seen more external tank problems due to the fact they corrode and leak and can get hit by road debris or other vehicles. But, each to there own,
Scott

Ok guys, the original question was not which option was safer, but if anyone had an easy option to move it. We all have our opinions, but none of us will convince each other which is better. Lets try to address what we can (the install options) and let the safety discussion rest. Have a great weekend!!

Safety is relevant to the discussion. The question was presented as follows:

Nomad 02 wrote: Anybody have a solution to getting the tank out of the cab without ordering a custom welding job?

48bigtrucks
(Scott) asked: Why do you want to move it?

Nomad02 answered: Safety and volume.

Here is an excellent article that shows the history of how gas tank safety was being discussed by the big 3 as early as 1964: http://www.autosafety.org/history-gm-side-saddle-gas-tank-defect

Here are some outakes from the article...

Like Ford and Chrysler, GM made pickups with gas tanks inside the cab in the 1960's. Because of concerns about the safety of placing the gas tank inside the passenger cab, the Big Three auto makers all considered relocating the tank outside the passenger compartment in the early 1970's.

GM engineers reached a similar conclusion in their early assessments with Chevrolet engineer Alex Mair recommending in 1964 that the fuel tank of the next generation pickup must be mounted outside the cab and as near the center of the vehicle as practical.

Oh, and for Scott who stated "I still can't remember ever hearing of any problems from cab tanks and they've been around for a hundred years." Here is an article about a couple who just this month were severely burned as a direct result of an in-cab fuel tank: http://www.fireengineering.com/news/wire...ublicationId=25

John,
Neither example you just posted said the tanks exploded on impact. They just leaked out fuel when the filler is pointed down in a roll over, just like any style of fuel tank would.

An in-cab tank only has it's profile pointing toward a potential impact with another car. It's also protected by the door pillar and door. It's also mounted above the frame inside the cab where it's protected from the weather and road debris.

A rear frame mounted tank could possible be opened up just by backing over something (seen it first hand), not possible with the cab style. Anyway, enough of the **** match. I did move my in cab tank to the rear of the frame on my 63 but not for safety reasons. I did it to add stereo equipment. Also, this truck sits about 3 feet off the ground and will not be driven daily. The weather won't have an effect on it at all. It's also encased in a class 3 receiver hitch to help in a rearend collision, or if a trailer would happen to come loose and start stabbing at the tank. It may even get a skid plate before it's done too.
There's my "common horse sense", whatever THAT is,
Scott

Horse Sense:
Nineteenth century horsemen noticed how cautious free horses naturally were. Horses voluntarily take no unnecessary risks. So horse sense means thinking before acting and taking the cautious approach.

Common Sense
sound practical judgment.

Common horse sense: think before acting and use sound practical judgement

Example: If you have the option don't sit in an enclosed area with 20 gallons of gas at your back.

John,
To each there own.

BTW, my tank is only 16 gallons.

At least it's not a VW with the tank in your lap!

I'm glad you feel safer having your tank mounted at the rear! I don't want anyone to ever feel unsafe while enjoying our old truck hobby!
Scott

48BigTrucks makes the statement: "They just leaked out fuel when the filler is pointed down in a roll over, just like any style of fuel tank would". This statement is incorrect.

A properly designed fuel tank system incorporates a non-vented filler cap and a roll over vent valve. By design this set-up will not leak, regardless of the orientation of the tank in an accident. The roll over valve has a ball check in it that seals if fluid backs up into the tube. Thus fumes vent out, but not liquid.

Here is a link to an article about a rear pick-up tank install where they show the use of a roll over valve:
http://www.customclassictrucks.com/techa...tall/index.html

And here is a link to Tanks. For a custom installation, or retrofit, they have all the parts to install the tank and vent it correctly: http://www.tanksinc.com/index.cfm/page/p...=prod/prd98.htm

Thanks

Give it a rest! That's all aftermarket and only works if it were to stay intact in an accident. You are not going to convince me and I don't care if I convince you. Each and every accident is different and no system is fool proof,

The basis of this website is to share information so others can learn from reading these threads. When an incorrect statement is made we are each obliged to correct it, not give it a rest.

This thread is about about moving the tank out of the cab for safety. If that is done a roll over vent valve should be used. It is a $11.00 item that could save a life. Even if the stock tank is left in the cab a rollover vent valve would be a good addition.

While your statement that no system is foolproof is correct, providing data on options to make the fuel tank safer is good information for our Stovebolt readers. What they choose to do with the information is just that, their choice.

I think I will go take a rest now. wave

John
