Crank case ventilation

    Setting up F134 today. Working on the vacuum system. I just bought a new fuel pump without the vacuum connections for the wipers because I am using electric models. My question is now that I don't have vacuum connections, How do I hook up the PCV valve and lines to the motor.

    Just straight line connecting the exhaust valve cover straight to the intake manifold on the head? No tee?

    Checked out the Crankcase vent tips on CJ3 page and no specific answer though there is mention of fuel pump without vacuum connections.

    Help is appreciated.

    on my 66 it runs from the valve cover thru a pcv valve attached to the intake side of the head:beer:

    Your existing PCV system will work just fine by capping off the old vacuum line from the windshield vacuum pump part of the old fuel pump.

    Just did the same thing a couple of weeks ago - changed to a vacuumless fuel pump. I used a plug at the "T" where the old pump attached. I think it's called an inverted flare plug? No problems. Or you can run a line straight to the intake as you suggested. :)
