I have a 1972 K10 LWB Custome/Deluxe.

1. Can anyone tell me, what the stock heigth would of been? I am trying to figure out how much sag has accrued over the past 35 years. Thinking of re-arching the springs.

2. I have a saddle tank(gas tank), on each side of the pickup. The three-way valve is in the cab. The only tank that I can read on the fuel guage is my cab tank. Does anyone know if these saddle tanks, were a factory option, dealer installed option, or after market? The info in my glove box does not specify the tanks. I know the saddle tanks, haven't been used since the early 90's. Does anyone know of a dealer that sell's replacement, along with the sending unit's for the fuel guage?

Thanks.

The GM restoration pack that I have for my 69 shows a 1969 K10 fleetside would measure 72 1/2" at the top of the roof. At the rear of the bed it should measure 47" from the top of the bed to the ground. Hope that helps a little. Those measurements were with a tire described as 8.25--15/4PR.

if your SPID label says nothing about saddles, then they didn't get installed on the assembly line. There were factory ones, there were tons of aftermarket ones, and there were dealer installed ones.

Thanks for the info so far....

Does anyone have this fuel tank set-up, and could give me their experiance?

The only factory aux. fuel option was on the driver side,had a boxed in chase inside the bed,and exited to a cap (no door),just like on the cab or the rear 1/4 on Suburbans,Blazers,and Panels.

I bought a fuel gauge and sender kit from JC Whitney for 20 or so dollars. It has been a LONG time so I don't remember the exact price.

When I bought my truck the auxiliary tank had a slow leak. The cowboy I bought it from (it was in Wyoming) said always use the extra tank first and swap it to the main when it starts to buck. I asked why and he replied then you always know how much is in there.

I asked about the leak and he said don't worry about it. I just told you to use it up first.

Anyways. I get the truck home and dropped the auxiliary tank. I sent it to a local radiator shop. They cleaned it out and sealed up the leak. While it was out I put in the JC Whitney gauge and sender. I mounted the gauge knee-knocker style under the ignition switch.

The radiator shop said most factory tanks are not fixable but these auxiliary tanks are made of plate and can be repaired. However being plate it was a bear to cut a hole in for the sender.

Because I'm a chicken I filled it up with water then used a hole saw to make the hole in the top of the tank. Yes a cutting torch or plasma cutter would work better but like I said, I'm a chicken.

I have 2 saddle tanks and they're dealer installed. The sending unit(s) and the 3-way valve still work for me. I also have a 3-way switch on the dash for selecting which tank to show on the fuel guage. I have heard saddle tanks are a thing of the past and nobody makes them anymore, or at least the ones in my truck. If your saddles are beyond repair, I recommend taking them to a fabricator and having new ones made. You can then buy a sending unit and modify it to work in the tank(s).


Good Luck
