Fuel Line Help Needed

[yj-mike]

I am installing an '04 4.0L into a YJ, and I am having some trouble with the fuel lines. I ordered a set of lines from the dealer and I am having trouble making the connections to the engine. It appears that there is one supply, and two vapor/excess return lines. One of the vapor lines seems to connect to a port on the intake manifold, but I am having trouble with the other one. The boot on it seems too big to connect to the other port.

Here is a picture with some questions and arrows showing the trouble I am having:

For the other two boots, does some kind of external fuel pressure regulator attach there? The boots are oriented outboard (facing the fender) so it seems that something must be mounted there that these connect to.

Also, I take it the green screw-off cap is a fuel pressure test port?

Lastly, anyone with a similar year Jeep living near Southeastern CT williing to stop by my house or meet somewhere so I can take a look under the hood/take some photo's?

Thanks,

Mike

Now you've opened a can of worms :lol:

The line with the green cap IS NOT a fuel line, it's part of the evaporitive emmissions system. It is a vapor line. Tank vent return line.
The line with 2 ports should have a purge valve connected to it and somehwere along those lines you should have a charcoal canister.

The line from the tank fuel supply connects to directly to the fuel rail where the injectors are.


It would be best to have someone with a similar Jeep stop by so you can figure this out and find out what other parts you may need.

Crzy,

Stopped by Valenti Jeep earlier today. Turns out a 'Duty Cycle Purge Solenoid' needs to be plumbed in there. Got one on order for $33.
