I;m having a hard time finding info on setting up a propane system for my truck. It's a 73 f100, 360. I want to keep the gasoline fuel system. I know that there are lots of dual fuel setups out there, I just can't find any info on them. Can anyone point me toward some books or links where I can get more info?

 

Get either a CA300-70 or a CA425M Mixer (And adaptors)from IMPCO They will work fairly well on or engine, I recommend the CA300 as it makes dual fuel easier. You will Need either a IMPCO Model E or a Century M6 Vaporiser, 2384B filter fuelock for LP, a gasoline lockoff and I would recomend a Dual Curve from Autoronics. There are some hoses and switches you need also and of course a tank which you might find used.
Contact your local LP dealer he should be able to order anything you need.
I sell the equipment but I cannot sell it retail you must work thru a dealer.
Any questions please give me a shout.

Looks like the Impco 425 mounts in place of a gasoline carb- Is it normally mounted differently in dual fuel setups, or can a mixer be mounted above the gas carb in a tall air filter?

 

The 425 can be mounted on a throttle body for dedicated LP. for dual fuel its usally mounted on an adaptor that offsets it sideways on top of the existing card, then a filter is installed on top of the 425 horizontally
