gas tanks

[jonesky2]

Going to order some spectra premium gas tanks for my 76 k10. Im converting it to tbi so getting the 87 tanks. Is spectra tanks any good? Any other better/recommend brands?

They show a 16 galllon and 20 gallon tanks. would the 20 gallon tank fit a short bed? I know the 16 gallon is the correct size just wondering.

does one tank fit both sides? doesnt show each individual side.

I bought my Spectra Premium tank from Rockauto for 60 dollars, I would check with them as you are going to need the fuel senders as well.

My research indicated the 20 gallon tanks will not fit a short bed due to the spring hanger location

I just want one that actually has some baffles in it so the needle doesn't wave like... something that waves a lot.

decided to order my tanks off ebay. I went with spectra premium tanks and was 178 for both tanks with free shipping.

In my opinion you get what you pay for. So I went for the little more expensive tank.

The spectra tanks are nice. They come with an anti-rust coating on them.

The "waving" of your fuel gauge needle is likely related to the aftermarket fuel sender likely in your tank now. Spectra sending units will cause the needle to bounce, Delco sending units won't. Spectra units are like $50, Delco units are like $150 - I chose $50 sending units and don't watch my needles very often.

They came with baffles and stopped the wavy needle?

i just put a spectra unit in my 79 no bouncy needle
didn't remember seeing any tank baffles either
tank made in Canada so it's fine
sender china ......fine so far

fixed bouncy needle in 78 when i changed the cluster and added grounds

The '87+ squares were TBI and had baffles in the tank. I would presume it was to keep sloshing fuel from pushing the pump around.

My needle was still very wavy until I replaced the fuel gauge with one from autometer. Now it still waves, but its less and much more deliberate looking. Like when you see a new car adjust more than once to find the fuel level. So I'm not sure what's going on there. Somebody said try a ground but a ground makes the resistance read off the charts and the gauge skyrockets to completely full no matter what the fuel level is really at.

When I say the needle bounces, I mean about 1/2" of travel from the accurate mark. I am not talking about swinging wildly from one extreme to the other - just enough to notice that the gauge is moving, not steady. Maybe some Spectra sending units are better than others.

[Skunksmash]

Yeah mine would swing about half the gauge width at any given time, with the factory fuel gauge. Installed a tach in its spot though, and downsized the fuel gauge to the old clock spot. This autometer gauge seems much more resistant to waving, but still does it.

I think what I'm going to do eventually, is probly go with some tanks (i got a "fuelis" lol) out of a newer truck that have baffles and that big chunk of.... foam or something in there that won't let the fuel slosh. Cause the factory tanks seem to fail at it even with their baffles so maybe they're not enough.
