Installation Guide For Rollover Check Valve and Liquid Check Valve On A 1976 CJ5?

In need of an organized guide for installing a rollover and liquid check valve. Including running the hoses and other essentials for completing the install. Pictures and diagrams would be great also! Thank You!!

In the October and early Nov threads maybe even Sept there was a lot on this topic.Some weren't by title but under charcoal cannister.Type roll over and liquid check valves in the search box and they should come up with plenty of pics

Advance Auto - Part # CP1061. Use promo code P20 and get 20% off.

You will have to make some slight modifications, but it's easy. Use the search tool and you will find many threads that cover it.

Sounds good! Another question.... how does the fuel filter return line end up at the charcoal canister if the return line goes from the gas tank to the fuel filter? Also which Fuel Vent Hose are they talking about in the picture above? There are 2 small vent hoses that come off the side of the tank and my diagram shows that they both go to the liquid check valve.... Im really confused!

The fuel filter return line doesn't end up at the charcoal canister. The line is in that last picture, but it itsn't going to the canister. The rubber fuel line you see going out of the bottom left corner of the picture go to the fuel filter.

The two lines from the tank go to the bottom of the liquid check valve (LCV). Then one line goes from the top of the LCV to the bottom of the rollover check valve (RCV). The line exits the top of the RCV and runs along the frame to the charcoal canister port labeled above as the fuel tank vent.

Just to let you know you're not crazy,
The diagram with two liquid check valves may be for a 20 gal tank.
The ones shown here is for a 15 gal tank.
