Do you have a vented cap?

I ordered my tank from Rick's Hot Rod Shop with a vent line that will be getting a charcoal canister attached to keep the fumes in check. I'd go that route.

Scott,
Do you have a part # for that canister? Trying to track one down myself

[Steve1968LS2]

I caped off the vent tube and ran a vented cap..

Had a hell of a time trying find a charcoal canister and the gas kept sloshing out the vent tube (bad location)..

Hey Steve1969LS1 do u have a rock valley tank if so which gas cap did you get cant find one anywhere thanks

I have a custom Rock Valley tank in my EFI 427 small block 56 Nomad -- and always smelled like gas in the garage after cruising... I've done everything I could think of to figure out where the "smell" was originating from.... now you guys have given me a clue! Never thought about the vent tube - and I have an UNVENTED O ringed thread cap! DUH!

Greg, did you find or add a charcoal canister yet. I spoke with Hector and Ricks hotrods where I bought my fuel tank. Awesome piece of work :thumbsup:. He said it was a must to limit that fuel smell. I haven't yet picked up a canister or figured how to install it. I guess I will need to run a vacuum line to the rear of the vehicle or a vent line to the front of the vehicle. either way I will have to run a long line in one direction.

So nobody has a item number, part number for this specical secret gas cap amazing

Charcoal canister part number GM17056292. Spoke with Aeromotive about the gas smell problem and a guy that builds high end Willys street rods uses this canister.

I had a problem with the fumes initially, and actually built my own charcoal canister with activated charcoal from a pet store. It seemed to work ok, but I was worried about getting enough airflow through it to feed the tank. I had looped some fuel line around to attach to this canister, and once I removed the canister I didn't really sense the smell as much anymore. It seems that looping some 2' or so of fuel line off of the vent tube has cut down the amount of fumes enough for me, and then I don't have to worry about the canister.

Good question - some of those things are huge.

http://www.sdpc2000.com has it for $45.

[DRJDVM's '69]

I'd like to know too, since I have a Ricks Hot Rod tank but havent installed it yet. I'd like to get everything planned out before I do the install....

Not sure about the size of the one that Payton supplied the part number for, but the one I plan on using is from a 90's full size blazer; it's about four inches in diameter by maybe ten inches tall - A hell of a lot smaller than the ones used in the eighties.

[Payton King]

What is the part number of the one from the blazer?

There is an easier solution. GM part# 10033125 is a small pressure valve that goes on the end of your vent line. Simply route the line outside and attach this small approx 1"x 2" valve. I run a orig 62 Rambler tank, in tank fuel pump and sump, stock cap as it is part of body, and this valve. When pressure builds that valve simply lets it out and then shuts again. A simple spring daiphram set up I believe.

Of course it has to be routed outside of the trunk area. Also if you have a trap door to access that tank make sure it is sealed with a gasket when it closes.


You should ask them exactly how they want that tank vented as you might collapse it if isn't braced but I am sure it is.

Good luck.

I don't have the part # in hand, but I've got a used one thats in storage. I'll try to get over there sometime this week to snap a pic and see if there is a part # on it.
