I'm switching over to propane and need some info on lines . Frist off I'm using a Impco425 mixer with a Impco mod#E vaporizer and a VFF30 fuel lock . All of this is going on mild 350 with 9 to 1 comp . What Dia hose should I be using to go between the vaporizer and the mixer? And what type of hose too? I was thinking of using hyd hose to go between the tank and the lock,is this a good idea?[I can make my own hose and for cheap too] Or should I use hose made to be used with propane?Also need a Dia on that hose too. Is length going to be a factor too?Especially the one going between the mixer and the Vap. I assume it should be as short as possible ? And the same for the one going between the lock and Vap? Thanks any info will help.
