Hello everyone,
I have a Nissan MPL02A25LV / PL02-9H3032 that is LP leaking into air filter housing after it's shut down. Not a huge leak but it's there.
I am unfamiliar with the injector carb set up on this unit and the vaporizer appears to be a NIKKI. Is there a low pressure fuel lock at the injector carb to stop fuel flow when the key is off? Maybe the seal or seat is bad. It seems that may be why it slowly leaks fuel into the air filter housing?
Thank you.

I would also check to make sure the injector housing isn't cracked around the inside of the bore of housing just above the butterfly ! We have had like 3 of them in the last few months that were cracked
First you could have a stuck fuel lock that is not shutting off also check the fuel pressure at the top of the Nikki converter there is a nut with a Phillips slot in it remove the nut and install a propane gage it should get approx 5psi with key on and hold steady when running could go up a few pounds with key on but should come back to 5psi. You could have bad o ring as stated by other post on main injector. if every thing checks out and you do not find anything wrong.the last thing that could be wrong is inside the main injector housing there are two popite valves that could stick if that is the case l would replace the main injector housing hope this helps
Thank you! I plan to go back and inspect it tomorrow.

Most likley cause is the Injector oring being cracked or broken. Remove the injector and inspect the end oring. If good then check the aux injector for sticking open (looks like a long hex nut with 2 black wires coming out the back).
Vapourizer should not cause this issue as this is a positive LP pressure system.
