Tank Venting
 

What's the simplest way to vent a DSE (Rock Valley) EFI tank?

Our solution is simple and effective. Install it in the trunk floor under the package tray and connect it to the vent port of the tank. There's no plumbing in the trunk, and no gas smell in your garage.

John can you explain how that device works or installs? Does this also keep the vent line from spilling out fuel on a full tank? You have my interest.

The vent is installed in the truck floor underneath the package tray with all plumbing interfaces on the outside (underneath) of the car. The tank vent port connects to the vent input port.

Installing our Vent along with an unvented fuel cap will virtually eliminate fuel smell from the vent port, and will cure fuel slosh problems that often happen with a full or nearly full tank. It will aid in burp-free fill-ups, and also provides filtered air to the tank as fuel is burned by the engine, easing the work of the fuel filter.

I got my II much vent today.Wow!!! this thing is an awesome pc.Well worth the money.And this from a guy who build's 90% of his own part's.:thumbsup: :thumbsup:

Thanks Scott! Your voicemail made my day! Now lets see some installation pics. :yes:

How much are they?

Kool product, I will be ordering two next week!

John,It is so refreshing to get part's that are way cooler than you expected.:thumbsup: :thumbsup:

I ordered one yesterday. Everyone with an EFI Tank from Ricks or DSE should have one of these mandatory if what it says it does works.

I even bought one as a diff breather :yes: . Can't say just how good this bit of kits is. Thanks Jp

May have to pick one of these up to go with my new narrowed Rick's tank.

what about a group buy?

I'm in! ;)

Me too!!

I have another question for some of you. I have a drop in Mustang EFI tank in my car. I am just getting ready to start looking into plumbing. While the tank and fittings are in the trunk, I plan to run the send/return lines along the frame and the vent up to the II much vent.

My question is, when I run those three hoses from the tank through the floor, should I just drill holes and use grommets, or does someone know of through the floor fittings I can use for fuel? I have never heard of anything like that, but would prefer to go that route.

Count me in for a group buy

What size line are you guys running?

My Ricks tank has two vent ports....when I talked to them about "why 2?"....they recommended I run both separately....with the Aeromotive pump they told me it will tend to create a vaccum in the tank if I only run one...

Seems like a PITA to have to run 2.....

I'm using a Ridetech fuel neck...which has a vent in the neck if I want to use that too...

A single 3/8" line is more than adequate to vent any tank up to about 2000 hp.

Air is replacing gasoline, and flows at approximately 25 gallons per minute through a 1/4" tube at atmospheric pressure. I've yet to see any fuel pump not on a Top Fuel dragster empty one of our fuel tanks in 40 seconds.

Hope that helps. :rules: :D

With those figures do you think a 1/4 inch line would be enough?

I'm running a vent off my diff too and figured 6 AN is overkill... So hoping running the same size lines will make it easier when buying hose and fittings

Yes. We use 6AN fittings in our vent because most tank vent ports are 1/4" pipe or 3/8" from the factory or vendor. But 1/4" OD tubing will work fine.
