Recently bought 400 lp. I would like a diagram on the lp fuel lines. Does anyone know how many of these were made? Do these make more power than a 400 gas? any hp tricks would be appreciated.
 
I'm MM but the LPs are all the same in operation. The VAPOR and LIQUID lines should tee, then go to the filter, then to the regulator. Always start and shut off the engine on VAPOR, I run mine on vapor until warmed up, then shut off the vapor valve, turn on the liquid valve. IF I'm not going to really load it, plowing or other HEAVY work, I stay on vapor. Once on liquid, run until ready to shut down, turn off the liquid valve and turn on the vapor valve, let the engine run to clear all the liquid out of the system then shut the engine down. IN the case of a Minnie, it's best to look at the temp gauge and shut it down after the temp goes down alittle from the work zone, could save a cracked head. Make sure it has a LP head, if it's a conversion with a gasoline head, it'll probably have less HP than gasoline.
