I'm in the process of converting the JTEC LDP system to the NGC NVLD system. I've already installed the NGC purge solenoid and have it wired up. I also bought a new NVLD pump (part # 4891427AB) and have the correct wires ran from the PCM.

The old LDP has a 2 large hose connections and a vacuum line connected to it coming from the purge solenoid. NVLD only has the 2 hoses connectors, not the little vacuum line. It almost looks like something else is supposed to go on top of the nvld pump.

Can anyone shed some light on how the NVLD system is hooked up? Thanks

This is what it shows in the manual so it doesn't look like I'm missing anything

Finally found the vacuum diagram. I guess I need to get a T fitting and hook that vacuum line into the one that is going to the fuel vapor canister. It would be sweet to see an actual pic of it if anyone has one.
