P.S. My K5 has a 31-32 gallon tank and the most I have ever put in it is 27.___ gallons.

A Little Extra Fuel Storage IDEA...

hmm thats retarted....why would they design the tank to be like that? I know it mixes in w/ the new fuel so you burn it all eventually but whats the point?
My saddle tanks are shaped funny too. I get about 2/3 of my running time on the first half and about 1/3 of my running time on the last 1/2 of the tank.
If I fill it all the way up it'll stay above the F for about two days (40 miles worth of to and from school driving and about 10 miles of misc. driving) then after it hits that F it drops like a rock. Just b/c of the shape. Hmm strange stuff.

I hear people say this all the time, and have thought it myself a couple of times. Is there any reality to this theory? That would mean the sender is not actually calibrated for volume but height of fluid alone. Any time I catch myself thinking this I figure it is the fuel above 'full' ie the filler spout that we are burning until the guage starts moving.
fireplug said:
That would make sense but isn't it on the same theory as the toilet floater? So it doesn't really know the volume but just the height it is at?

Honestly I don't know. But if it was that simple the fuel level would be flying all over the place when accelerating, braking, up and down hills...

I believe the float pivots near the top, like a regular toilet, so its moving faster towards the bottom.

In my old '79 LWB I had dual 16's and just for S&G I purposely ran 1 tank out until it sputtered. It went 20 miles after the gauge was pegged empty, and took 15.5 when I filled it back up. The most it ever took when I was just being normal was high 13's

The gauge has a delay. It masks the fluctuations.

In gallons, how big is the '69-'72 truck fuel tank? The tank that sits right behind the driver/passenger.
I was thinking about squeezing one of these between a pair of main roll cage hoops. In my opinion, in regards to weight distribution, that is the IDEAL place to put the fuel. But it would get in the way when the fiberglass top is on.

Exactly what I'd do were I considering it.beater_k20 said:
Crew Cabs had that option for sure, possibly an option for all long beds? A friend has the pair of tanks out of a '73 std. cab long bed. FS btw.Avery4jc said:
During the fuel crunch of the early 70's the Feds outlawed fuel transfer systems like this. Enough people died b/c of them that the feds took notice and took action. For some reason diesel fuel systems are exempted.WRENCH-HEAD said:
As I see it the location fore to aft is good, but it's too high. Would be better off sinking a Sub fuel tank thru the floor in that general location.CDA 455 said:
The problem with the idea, as I see it, is the weight of the fuel. If you're hauling something heavy then the extra 264 lbs (6.6 lbs/gal) of fuel weight may not matter much. However, if just an empty truck that's a significant amount of weight.

Thats exactly what mine does
. It does get a little annoying but its also fun to play the game lets see where the fuel level will be at this red light.
1987Chevy said:Thats exactly what mine does
Yeah mine does that too if I really have to get into the brakes...the saddle tanks, well all tanks for that matter should have baffles (sp?) in them to prevent sloshing so fireplug I bet they do work like that we just don't notice it because of the tank design...

Just for interest sake there was no baffle in my Burbs tank. Don't know about my Blazer's though.
fireplug said:
hmmm, I figured it almost wouldn't be a choice for GM/Chevy to put a baffle in...even with the small saddle tanks 13 (maybe 15ish, we don't seem to know) is still enough liquid that I wouldn't want sloshing around...not to mention the huge 30+ gallon burb tanks.

Avery, saddle tanks are 16 gallons, and 20 gallons, we do "seem to know".
as for worrying about baffles, if it really bothers you guys that much, get the TBI version of your tank, they've already got baffles in them.

Can't say it's really bothering me all that much.
The burb tank I mentioned was a TBI though, no baffles. Maybe an aftermarket?
beater_k20 said:
Yeah thats what we were all thinking in the posts above...nobody seemed to have a straight answer except we all agreed on the fact that they hold more fuel than what we put into them even when they are on E. Like I said I have never been able to fit more than 13 gallons in mine, ever.

i've seen quite a few that the baffles broke free. maybe at some point they came loose, and were removed by a PO? or an earlier or aftermarket tank was swapped in.

How would you remove them? Are they that small?

Avery, the extra gasoline in your tank after your truck reads empty is a reserve so you can get to a gas station, thats why they do that. As for the baffles, I have a FI truck and my baffles may not be there anymore. When the tank gets low and I take a right hand turn it cuts off the fuel and my truck sputters... I should drop the tank and look into this.
