One of the biggest problems with the newer fuel systems. If you have tar in the vaporizer then you most likely have through the whole fuel system. It really is not a bad design for the fuel system but mostly due to cheap LP fuel being used. If you do not specify what type of LP fuel you are most likely getting what they commonly call farm grade which has a lot of impurities in it and is fine if you are using it for your grill or something like that but not good for the newer fuel systems.
The vaporizer had a ton of tar in it. Im taking over for a mechanic that has retired and I have no documentation of it being drained
i also have a fuel filter on order for it too
Komatsu or Nissan part number is 16310-FT860 for the vaporizer. You will be further ahead buying a new unit and they are available in the aftermarket made by the same supplier as the OEM. With the technology built into trucks now days if you start messing with the fuel system or adding extra components, instead of fixing it correctly, it can create other issues. As I was always taught fix it right the first time otherwise you will spend 5 times the amount down the road.
That'll only be a temporary fix. It will, at some point, become unusable as the regulator becomes more clogged with tar. Forklifts aren't cheap to maintain, you'd better get used to spending money keeping it operational. Keep in mind that evertime you modify the lift in the hopes of saving money, the more liability you take on yourself, IMHO.
sounds like itll be cheaper to just splice in a coolant block heater circulating pump
Sorry, a cold start issue is usually a regulator issue. Filters, spark plugs etc have their own sets of symptoms which generally aren't cold start issues.

So im at replacing the metering device for a cold start No filters or anything easy relatively cheap to fix for the Cold start?
The regulator is usually beside the battery. It'll have coolant hosing as well as LP hosing attached to it. I would recommend you replace this with a new one from the dealer as they are precise metering devices which will be difficult for you to rebuild aa you have no experience with these. Be ready- these are expensive.
Also- make sure your LP supplier is selling you grade HD-5 propane as these regulators are sensitive to contaminants & tar buildup.
I do not know Im new to propane equipment Ill have to look
This truck has either the Nissan K21 or K25 engine so it will have pretty much the same fuel system that everyone else uses for this engine.
How is the fuel delivered to the injectors? Does it come directly from the fuel lockoff?
Its a fuel injected nissan Where is the regulator to clean up?
He is referring to the fuel regulator, mixer/carburetor and or the fuel lockoff. These can get gummed up with tar from the fuel and cause problems when cold.
Sounds like your propane system needs service.
