so i just bought my first dual fuel truck, a '94 F350 460. its working pretty good actually but i've got a couple questions. 1. during the winters here ( -20 average) would it make any sense to heat the tank a little? ive noticed when using torches that if you heat the bottles they last alot longer. would this apply to my truck? and 2, is there any specific spark plugs i should be using?

 

No you do not need to heat the tank. The engine vaporiser will keep the fuel volume and pressure where it needs to be. That being said you need to allow the truck to warm up from a dead cold start or you will end up with a block of ice under the hood instaed of a vaporiser. Rule of thumb has been to run a range or two colder on LP but since you are dual fuel I would not.

Regards

 

Stella! thanks!
