Gas tank question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Piotrowski102 · 03-12-2008, 10:44 PM

Im looking at getting an 85 K10 thats for sale in my area. When I went to look at it with my dad we noticed that the truck only had the pasanger side gas tank, no drivers side tank. I asked my friend about this and he said that his 78 also only has one tank. So my question is are the trucks supose to have two tanks or just the one? Hopefuly some one has the answer and thanks in advance.

So since the truck is an 85 im guessing it has doors on both sides, becuase I am pretty sure that that late the trucks with only one tank only had them on the drivers side. I could be wrong though. Does it have two fuel doors?

My 84,86,87 had the tank on the drivers side. Im pretty sure the older ones are on the passenger side 79 and older??

Ya the trucks got fuel doors on both sides but only the pasanger side has a tank. My only consern is I dont know how far ill get on one 20 gal tank of gas.

SRH916 · 03-12-2008, 11:10 PM

Well, I dont get that far on mine

I have two tanks, but one of mine hasn't been used in some 20 or so years... Don't even wanna try.

Does it have the tank selector switch in the cab? If not then the bedside may have been replaced at some point in time.

I suspect that either the bed has been swapped from a dual-tanked truck, or a leaky left tank was deleted at some point to pass inspection... the latter is common in rust-prone East Coast trucks.

Dual tanks were an option on all trucks. A lot of them came with only one tank, and far more than those with dual tanks.

So are you saying that most of em came with dual tank doors but only one tank?

**old Rusty C10** · 03-13-2008, 06:07 AM

i think hes trying to say that someone either swapped the bed or the bed side on a one tank truck with a dual tank bed which is entirely possible. I did the same thing once in desperation. If there is evidence of frame straps for the tank or a dual tank switch on the dash then it was a dual tank truck

Piotrowski102 · 03-13-2008, 06:50 AM

Alright guys thanks for the replys Ill look for that switch next time I go to look at it

No, I am saying the majority of the trucks came with only one tank (and one door). If it has 2 doors and only one tank with no switch, someone swapped the bed.

I agree my 76 had pass. side tank only, and the 86 4x4 and 84 2wd both have only one tank, one door and it's driver's side.

If you got both fuel doors already, then you can add the dual tank setup real easy. The wiring harness and switch is a add on deal separate from the main harness so it's easily removed from a donor truck.
