    Help Vapor lock

    So after a few years with my current CJ7 the dreaded vapor lock has reared its head, so far the fuel lines are insulated. My thought now is perhaps a ball valve on the hot water hose that passes hot coolant in the manifold for the frozen cold season. Shut off in may open in sept. Thoughts...

    Vapor Lock/Heat Soak Problems

    Any time I go on a long trip 1hr+ (Especially in Summer). If I stop the engine for a short period (gas station fillup), when I go to restart it, my CJ rides super rough and stalls out. It eventually comes back to life after stepping on the gas for a while. I'm thinking its a Vapor Lock/Heat Soak...

    Fuel vapor can, vacuum system questions

    So here's what I'm dealing with... Rear port on engine manifold has no hose connected - occasionally sprays oil spittle onto the firewall. Hose from windshield washer bottle goes to vapor can. I have an open port on my carb air filter (which I'm pretty sure is not the original carb - way too...

    Replacement Vapor Cannister

    I am planning on redoing my fuel system in the spring and am starting to research and source parts. I am going to go with the MTS 21 gallon Poly tank upgrade and mostly stick with MTS replacement parts because I get just about everything for that from JC Whitney. I will be replacing most...

    Vapor canister hose routing (no EGR/Cat.converter/O2 sensor)

    Can someone explain how to connect/route hoses to the aftermarket vapor canister (CP3045) for a 1983 CJ5 with a weber 32/36 carb, and no emissions components. I live in a place that does not require it. I simply need to get rid of the fumes/smell. Any help is greatly appreciated. Thanks!

    Fuel tank vapor vent lines

    I recently had to replace the vapor vent lines and I am continually having leaks from the hoses now. The PO had spliced two different sized hoses together instead of buying the proper hose and then over the years his fix dry rotted. At the time I didn't know what the plastic container that they...

    Vapor lock

    Greetings, Recently started having vapor lock issues. A little background. The cj was running rough, rebuilt the stock carb and lost spark while tuning it, alternator was putting out 16+ volts and fried the computer. Did a nutter bypass and upgraded to weber carb since I couldn't get the carter...

    CJ Poly Fuel Tank Vapor Valves and Grommets

    Currently working on an 84 CJ7 fuel tank. Its the 20 gal poly tank. It has two vapor valves on top that could stand replacing along with the grommets. Problem is that I cant find any valves or grommets for the CJ. I see them for YJ's and they look similar. Will the ones for the YJ work on the CJ...

    Vapor roll over valve

    My '75 is missing the vapor roll over valve it should have. There were two on later CJ's one was metal the other was larger and plastic made to cut off possible fuel flow to the vapor canister. I need the bigger plastic one, does anyone have any idea where such a critter can be found new or...

    Replacement Fuel vapor canister.

    Hello, I'm looking for a charcol canister. Does anyone know of a part number that I can use for my 76' CJ5? I've seen some for other vehicles that might work, but don't want to buy if I don't know for certain. Thank you

I got to the house and popped the hood and noticed what looks like steam coming from the oil filler tube. I let the jeep sit a few hours and then...

    Fuel Vapor Vent Lines

    Hey guys...I am going to put a new fuel tank in soon. I have the tank and all my lines. I have noticed a few pictures where people have basically blocked off the 2 vapor vents on the tank by just putting 1 piece of hose between the 2...if that makes sense?? Rather than going up to the liquid...
