Fuel tanks leaking

[74 shortbed 406]

I have a 87 k10 that has dual tanks. The pass. side tank has not been used since I bought the truck(1 yr ago) and previous said he didn't use it because it leaked. Now the drivers side is leaking and I am wanting to replace both tanks and get them both to work. I was just wondering who has the cheapest tanks and what all the dual tank consists of. This is the first time dealing with duals. Also, what do you all recommend, take bed off or drop tanks.

i think you'll have to remove the be to drop the tanks, my brother did a diesel to gas conversion some years back on a 85, he said he had to remove the bed to drop the tanks and drain the diesel

You don't have to remove the bed I replaced the driver side tank on my 87 swb. Hopefully your tank frame brackets aren't rotted away, like mine were. I got my new tank from the local pepboys it wasn't that much. I also bought new straps and a new fuel pump. The pump wires unplug but there was one little stubborn ground wire I had to cut and then I just re-spliced it when I installed the new tank. Hardest part is lining the holes up on the frame. You will need a floor jack to hold the tank and brackets up while you try to align. I'm a small guy and was able to do this job with the bed on.

Around Kansas city the auto parts stores were looking to make a pretty good profit for a gas tank. About $50 over Ebay prices so I bought my last tank there. From the same seller I bought new straps Made the job a lot easier. Pulling the bed isn't necessary actually it will only help with unhooking and hooking the lines on top. With that said if the bolts will come out I would recommend removing the bed. Since you are planning on doing both tanks It might be necessary

Done it both ways with bed on and bed off. WAY easier with bed off. Look online for tanks and brackets. Bought mine (the tank) on ebay, they're always there. Brackets got from the junk yard, took some time to find good ones though.

Use new tanks and tank supports. Using old supports as a guide, put 3/8 X 1 bolts into each of the 4 bolt holes in each support assembly making sure the head of the bolt is towards the tank and tighten them up. Now weld the bolt head to the bracket and remove the nut. Next, again using the old tank\bracket assembly as a guide, assemble new tanks and brackets making sure to use some type of insulation between tank and bracket. Heavy roofing felt or tire tube will work fine. This makes installing the tank a 1 man operation with the bed off or on. PLEASE NOTE!! Front and rear supports are different!!! Before you weld anything up make absolutely sure they are in the correct locations and that the bolts you are going to weld in are in the right holes for your application. Also, the front bracket has 2 holes in it for the strap bolt\stud to go through!! Make sure you put yours in the same hole or the tank won't mount. I do believe tank supports are still available from GM. I got mine there 6 months ago. You would be well advised at this point to replace the senders too. It's cheap insurance. jim
