Actual Capacity of K/5 Belly Tank? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Funny, though. LMC Catalog lists the Blazer/Suburban tank as 21 Gallons.
Conversion belly tanks for under pickups are 17 Gallons.
And Truck and Car Shop calls theirs a 20 Gallon tank...
Pretty sure mine's an original.

I noticed that Some of the vendors, when searching for capacity,
Was different.

I had a 76 Blazer that had a 31-gallon tank.

This is what sparked my curiosity.

The only true way too tell what yours holds (you Know),
Run it out of gas and have a (measured amount to add back).
