Your truck's LPG fuel system has been modified from OEM. We have done some research and the components you have on the truck now are much larger then originals. The VFF30 - filter/lock off (56.97 USD) is correct. The model L has been changed from the model J (70.74 USD) Nissan part No. 16010-JBREG and the mixer CA125 has been change from the original CA 50 (257.01 USD) Nissan part No. 16010-CA50M. If you are removing the 5/8 dia. hose from the vapor/reg to start and run the engine you no doubt have raw LPG coming from the vac. lock off's vac. hose.
