Guys, I have '82 S10 drag truck.
When I bought it 12 years ago the large fuel cell was installed in the rear of the box, and I've never done anything with it.

The battery is still under the hood, but I plan to relocate it to the back.

I see other S10s locally that are similar.

But I see though that the IHRA rule book appears to forbid mounting fuel cells and batteries above the level of the rear tires.

Tech has never gigged me for it, although they've never looked under my tonneau cover.

In 2023, I narrowly missed out on qualifying to race in the IHRA World Finals. If by some stroke of luck I qualify this year, I may need to reconfigure things a bit to pass tech there.

I may "over think" things on occasion, but I don't want to tow 900 miles to be told I can't pass tech.

Can anyone tell me why one must keep fuel cells and batteries pretty low like that?

What do you other S10 racers do?

I don't really want to ask my local tech inspector, just because......

Thanks a bunch!

We have both the battery and the fuel cell mounted under the bed behind the rear end.
The battery hold-down I think came from Speedway motors.

I bet they are saying mounted above the top of the tires, I would find it hard to believe that yours is that high, if it is then lower it down if your worried about it

I have my 5 gallon cell mounted in the middle of the bed above the rear end, with 2 batteries directly behind it. Never had a problem with tech until a few years ago during tech for the division finals, was told to put batteries in a box, which I did for the next season.

In my truck I have the fuel cell in the back sitting flat on the bed with a battery on each side, have never had a issue with tech. I think as long as the they are in the bed and you can't see then sticking above the bed line your fine.

Fuel cell on the floor of the bed, battery on the floor to one side of it. NEVER had an issue. Just use the proper mounting bolts and vent fuel tank below or outside the box.

Tech card is supposed to be filled out by the track you run at, it's all an honor system. If you raced at your track and qualified don't worry shouldn't be any tech at the bracket finals or world finals.
The S10 I had and most just have the cell on the bed floor along with the batteries. I think the rule is above the top of the rear tires.
I've see 3rd gen Camaros with the cell mounted behind the rear seat up high inside the car running at a sanctioned track.
