Car Forum / Driving, Maintenance, Tuning / 4x4 Cars / October 2006Auxiliary Gas Tank 1971 Chevy K20, 3/4-ton 4wd
Hi, Want to buy and install another gas tank under the bed of this truck. Where can I buy one. Have spent hours searching the net in all the usual places and more... All I find is for late models. Some have told me I have a 1-ton. Who can tell me if the 3/4-ton and 1-ton have the same frame? I know the read diff is 1-ton, but the truck was sold to me as a 3/4 and the VIN is to a 3/4. Thanks, Vic ----------------------------------------------------------------- 1971 Chevrolet K20 3/4 ton pickup Fleetside long bed 4WD 350 4 on the floor Transmission - Muncie 465 Transfer case - New Process 205 Warn manual hubs Front Diff - Dana 44 Rear Diff - Eaton H070 should be an H052 for 3/4-ton, H072 for 1-ton. current diff is a 1-ton from a 1965 truck. > Hi, > [quoted text clipped - 27 lines] > H072 for 1-ton. > current diff is a 1-ton from a 1965 truck. First the HO72 is common to find in a 3/4 ton of the era with a 4 speed SM465 so it is still a 3/4 ton. (I had a 66 3/4 ton with a 6 and a 4speed than had the HO72 in it too) Also internally the 52 and 72 are same axle except for a adjustable ring gear thrust pad. On the fuel tank, It was possible to get uo to two aux tanks from factory back then. I had a 72 3/4 ton 4x4 same drive train (except spicer axles and lockout hubs because it was a GMC and they came with spicers back then) and with one aux tank from factory and drove it for 10 years and loved the dual tank setup a lot. They mounted in bed fenderwell between wheel well and front of bed and had a filler through side of bed from factory with a manual valve on floor between seat and door and a switch on dashboard to select which tank to read from. The aux tanks held about 16 gallons each ----------------- TheSnoMan.com |> Hi, |> [quoted text clipped - 42 lines] | seat and door and a switch on dashboard to select which tank to read | from.

There was no HO70 per say, only a HO52 and HO72. There was a few D70's used in some trucks in 70's (D70's were used on some 1 ton models and may have made it into a few 3/4 tons) >Yes, I know they came with back in the day. >Where can I get one now? Bone yard unless you can still get them through a GM dealer at a high cost. They were optioned on 67 to 72 models and after that they had a different aux tank option for a bit. Besides having them myself I have seen other old trucks with them from time to time. Years ago I knew a guy that had the little known "longHorn" ( a GM P/U with a 8 foot 8 inch bed made only a few years in the metioned body style) and it had aux tanks too from factory too.I remember when GM used to offer 20 and 30 gallon tanks as options on blazers and a 40 gallon option on suburbans. (I have one) You could adapt one of these 20.30 or 40 gallon tanks to your truck (they were offered through 91 on burbs and blazers) if you relocated the spare tire and its rack as it would basically be a bolt it of sorts. ----------------- TheSnoMan.com >|> Hi, >|> [quoted text clipped - 51 lines] > > Vic Just watched "Trucks" on TV on Saturday and they are working on "Project Copperhead" which is a truck of that vintage. Was installing a new aluminum gas tank between the frame rails and behind the rear end. Ever notice how that guy has no dirt on his hands and just goes and buys any old thing he can think of and bolts it on? Wonder if he can work on a real truck or just assemble new parts? - Regards Gordie On Mon, 16 Oct 2006 20:26:50 -0400, The Nolalu Barn Owl <gordie@nolalu.on.ca> wrote: >Ever notice how that guy has no dirt on his hands and just goes and >buys any old thing he can think of and bolts it on?

Yes good point it is a lot easier to build new than repair old! ----------------- TheSnoMan.com I've got the twin side tanks on a "pick-up bed" trailer and would sell.

I'm | near Atlanta post back if interested | LD LD, You bet! But I would like to verify the truck is correct. Can you email or post some pictures of the under side of your trailer? Please include a shot showing the rear and side of the body. Vic I emailed this note to you yesterday. Maybe it is not your real email address above? You can email me at vic564738 ignore at the gmail words dot in com this Thanks for the Copperhead tip. http://www.staceydavid.com/projects/copperhead.htm http://www.earlyclassic.com/tech.aspx?category=Go%20Farther Just have to decide where to move the spare tire to. Wish there was a side tank to be found. Vic Vic, Don't know if you have been to this site yet: http://67-72chevytrucks.com/vboard/ Scroll down to the section that covers your truck. You have to do a simple register to post or access some areas but it's not a biggie. The problem with getting a yard tank around here is the first thing they do is punch a hole in it and drain the gas out.
