I hate my 16 gal. tank

[1987Chevy]

I have a short bed with a 16 gallon gas tank and just like the title says I hate it . the stupid thing goes through gas way to fast. I was wondering if a 20 gallon tank out of a long bed could fit in there with a little bit of tweaking and how hard it would be to install cause an extra 4 gallons would give me like an extra 50 miles to a tank and that would be nice. Any help would be greatly appreciated. thanks

The 20 gallon is longer. You run into the spring hanger at the rear, or run out of floor 'bubble' at the front.

I like the rear tanks - 25 or 31 gallon - used in the Blazer & Jimmy.

convert to dual 16s (one on each side) thats what i had in my shortbed

I have the 31 gallon. You really should look for one if you are going to go to the trouble to do a swap. They usually came with a heavy duty skidplate and are pretty out of the way. You would have to be really trying hard to dent it. I have put some scratches in the skidplate and I only run 35s. The rear tank is also less trouble to hang. You would eliminate the need for the tank selection thing.

Amen! When I bought my crewcab, it had dual 20's ... but the switch between them was bad, and one wasn't even plumbed

Your shortbed prolly gets better mileage than my sixpack, but I can't imagine having a 16 gallon tank ... it's bad enough with the 40

On a related topic, I've heared mention of kits to cross-fill, i.e. fill both tanks from one side. Anybody have any info on this?

Alternately, can I make one tank feed into the other somehow? I think "gravity-fed" tanks are a no-no for CA emissions, which makes me want to do it all the more (truck is pre-smog, so they'll never see it ) I could even put a Blazer tank into the back under the bed, but I REALLY don't want to add ANOTHER tank switch setup... too complex, too much $$.

You would think that you could replace the switch with just a T or Y hose fitting so that it feeds out of both tanks at once, but then you would have to pay attention to the fuel guage because there would be no backup tank.

Well, the problem is that there are three lines to split, right ... fuel to the pump, a return line from the pump or carb or something, and a vent line, maybe? IIRC the switch I used had nine fittings, i.e. three in from each tank and three out to the fuel lines.

I only have 18 gallon tank(s).... one on each side.. it is nice but since it isnt a daily driver I only fill one.... to fill both is a pain as I have to pull up and fill one.. turn around and fill the other...

I was thinking about those but I thought I would like the 20 gallon better because with the price of gas these days I would have to take out a small loan to fill a 31 gallon tank.

i had a bad switch on mine too so i just hooked up an electric pump off of one tank to a switch in the dash and used it as a transfer pump.
