What are my options in replacing factory fuel tank? Tank was 21 gallons i believe. Do they make a larger stock unit that will bolt in? Would rather not run a fuel cell and the stock tank is kinda beat up on the bottom. I removed to weld my cage tie ins because i didn't wanna get dead if there were fumes a leakin. Next tank will have a skid plate but need some info. Thanks.

Guess it would help if i told everyone what i have. 1977 k5 blazer with a 350/465/205. Thanks!

'Burbs have 40s and skid plates.

K5s had an optional 31-gallon tank too. It's 2-3" deeper than the 25-gallon.

The 40gal Burb tank is a nice idea... but its 6" longer that the K5 tanks.

Where can i get a new 31 gallon tank besides from the dealer?

LMC truck. I got a new 31 gal fuel tank and pickup/sending unit from them for my 74 K5. I don't remember how much it was, but I'm pretty sure it was under 200 for both. Good quality parts that fit with no problems at all.

Not sure where in the USA.

When I bought mine (6 yrs ago?) it was $120 CDN from a local jobber-body-parts supplier. It was this brand: http://www.spectrapremium.com/
