Keith462 thanks for the pics and the info on the "smelling like gas" Do you make your own gas lines? If not where can I find the line that does not go into the canister. I have that one that goes into the canister. Thanks again for all the pics and info! really helps

Thanks for all of the pics Keith! I am just starting my rebuild and have already discovered that the PO had no idea how to run a gas line... Only one from the tank, no return and everything is rotted rubber.

One question about InlineTube.com. I have a 72 cj5 with a 304 and I have looked everywhere for fuel lines and cannot find them, would the lines for 76 and up still fit on mine?

Probably not. The frames changed in '76, so the fuel line bends and lengths would be different.

Any idea on tracking down gas lines for a 72 with amc 304, or how to go about making new ones?

1972 CJ5 - AMC 304 V8 - T-15 trans
Dana 20 transfer - Dana 30 front - Dana 44 rear

Currently being taken apart, so that it can be put back together.

Removing the canister, you will experience the joys of smelling like raw fuel every time you drive your Jeep. But, if that is what you like, go for it.

Fuel tank venting, Roll Over Valves, fuel Check Valves, Return Lines, Charcoal Canister and dual outlet Fuel Filters are all designed for a purpose. For the purpose of delivering fuel to the engine and returning unused back to the tank safely without you having to smell it.











My stock tank didnt come with the two vent valves on the left side in these pics... what do I do???? also I bought a new tank and it has those on it.. this tank came with a tie down bracket that is way to big to me.. unless I'm looking at it wrong??

If your aftermarket tank already has the Roll Over check valves in it, then you don't need them. Even the factory OEM 20 gallon tank did not have these either, but all the 15 gallon tanks do.

As far as that strap mounting goes, they probably have made it long so you can cut off the excess that is not needed.

My 20 gallon tank has roll over check valves in the top in two locations. I simply put a T in the line, hooking them together and on the other end I put this.



Basically I hook the vent line to the filter to keep any dust from entering the system. The loop at the top keeps any fluid from running in. This is stuffed way up high above the gas filler on the passenger rear.

I don't run a charcoal canister and don't get any smell. My motor is properly tuned, no gas leaks, etc. I have just a supply line, filter, and return line.



I don't have any issues with vapor lock or smell. The motor runs great.

Beat it to fit, paint it to match!

Wheel, Wrench, Repeat.

Would it make a difference if I have the 258 inline 6? I noticed you have a V8? regarding the gas smell and tuning with the charcoal canister.. On the note of the two vent holes.. should I just plug them? or I was thinking of making a Y and just combined them into the charcoal vent line???? any thoughts??

Mine originally had the 258 in it.

Your tank should look like this on the top.



The two connections where the Y is hooked into, have liquid check valves built into them. That is what I have the filter/looped end hooked into. The other connections are on the fuel sending unit. One is the fuel supply, other is the return line from the filter.

I am in the process of installing a return and vapor line on my 1984 CJ7 (both were removed by PO), and I am trying to understand the connections. Are you saying my existing fuel supply line will be coming off of one of those nipples, and that I should create a y connection for the return line? What about the vapor line from the charcoal canister? (also installing one of those this week)

Thanks in advance for your help!

The fuel supply is the larger hose nipple in the sending unit. The return is the smaller one and there is only one return line and one place to connect it. The vent goes to the two with hoses in that photo. You can see where it splits at the bottom of the photo.

Oh I see now- so the return and supply nipples don't have lines hooked up in this photo. Got it.

So do I need to split my vapor line to those two nipples line shown in this photo? Or just run direct to one?
