The Stovebolt Site Forums The Shop Area The HiPo Shop Roll Over Valve on under bed tank

Hello all...
I've removed the after market tank that the PO had put in the bed of my '63 and purchased a new repop surburban tank from CPP to install between the frame rails under the bed. I feel like I should put a roll over valve on the tank. Any comments on which one or where to get it? Summit & Jegs both have several options that I've found. Is one better than the other? Do other vendors offer better options? Thanks...

I really can't give you an answer on which is better or who to get one from, but just out of curiosity, why do you think you need one? There just isn't much of a need for one unless you're going to be racing it. If it was really necessary, the tank would probably either had one in it, or be set up for one. Most of those valves are really made for use with a racing type feul call, not a street vehicle type tank.

I'm not real sure that I do need one...it just seemed like a good idea. I won't be racing the truck, just daily driving.

Unless the gas cap falls off, you won't lose much gas in a roll over. More will come out the vent than the cap,

If you've changed the fuel pump to an electric one you'll pump fuel everywhere in a roll over unless you install roll over valve seeing as the ignition will still be on and the pump will be running. I installed one of the Holley ones from Jegs. Better safe than sorry but that's just my two cents worth.

I beleive what Texmo is looking at is a rollover valve on the filler neck. On the pump, most modern vehicles use a switch to cut power to the pump once the vehicle goes beyond a set angle. I would think that the aftermarket would have something similar.

Or the pump is wired to an oil pressure switch so that it quits pumping when the engine stalls.

This is a K.I.S.S. installation so no electric fuel pump. All I was looking for was something to put on the vent line. I'm still running a mechanical fuel pump and have no immediate plans to change.

Texmo, go to the local auto parts store and get a one way vacuum line check valve. I use one on my vent line so the garage doesn't stink. It lets air in the tank, but not out. Its kinda like the power brake booster valve only smaller. My local NAPA guy knew just what I wanted, something off a Ford if I remember right. One side is white, the other black. Joe

Joe that sounds like exactly what I was looking for. Thanks!

this is what he wants
