What capacity fuel cell would you choose for a DD/Trail Rig?

[handloader90]

Throwing around the thought of a steel cased bladder style fuel cell. Jaz to be specific.

They offer them in 16, 22 and 32 gallon (and a few others).

Truck will be daily driven on a semi-regular basis and driven to and from the trail.

My first though was the 32 gallon but it's pretty tall, I believe around 18" or so. I can carry the same amount of fuel as a 22 gallon + x2 5 gallon jerry cans though with the 32 gallon cell and minimize the amount of real estate my overall amount fuel would be taking up.

The fuel cell will be mounted to a flatbed so figuring out how/where to mount it won't be am issue as opposed to if it were going in a factory bed.

Thoughts?

I have a 20 gallon cell in my K5. Works good for me. I haven't had an issue with running low on gas. I've wheeled for a weekend (fri,sat,sun) and only had to fill up once while there.

Do you ever feel the need for more fuel.

 

[GWeakland620]

Not yet. The only time I feel I would need it is if I did more expo style road trips.

I use about 12-14 gallons in a day wheelin with my big block. I can't imagine not having at least 32 gallons for a full weekend.

Big block? Small block?

Mileage expectations?

I prefer more capacity

I agree.

I just swapped out my 25 for a 31 gallon and I'll still carry a Jerry can.

6.0L LQ4 with an e85 converted holley truck avenger carb.

I'm hoping for 10-12 MPG.

E85? Then you need a bigger tank.

Had 16 in my old K5. I would have gone larger, but 22 should be awesome

Was planning on doing the e85 conversion to the carb. e85 burns off faster than 87?

 

[Tweekls1]

Yep, e85 def burns faster.

 

[skunked]

I forget how much but I want to say it's roughly 20%. So you need a 20% larger tank than someone running fuel.....

 

[handloader90]

Well maybe I wont do the conversion. The cost of e85 doesnt justify having to use that much more of it.

The e85 kit cost about the same as a new carb so I can spend the cash somewhere else...

Friend of mine logged 150% consumption on E85 over 91 octane

Jeez...

I've been using 87 here in CO. When I was in TN I ran 89 but I haven't seen 89 at any gas station I've filled up at here, they have 85, 87 or 91.

I'm a fan of 91

I'm too cheap for it with as much draining as I do. Maybe I'll switch since it doesn't burn off as fast as 87.

Ask @mrk5 about that

Higher altitude means less air pressure which leads to less cylinder pressure for the same compression ratio. So the octane in the fuel can be lower, so that's what they sell here. Ok for stock, otherwise, lame. Not like it costs less or anything.
