I had envisioned a system similar to the one you describe. I don't expect 
freezing to be an issue with just one or more likely two 30 lb/hr injectors 
on an engine making ~30hp. I will use as long of a hose between the tank and

regulator as necessary to keep from "going liquid" as us paintballers say. I

will probably experiment with copper pipe to make a fuel rail I can solder 
together. That way I can put whatever fittings I need wherever I want

I wouldn't normally consider propane an option, but I only know of one or 
two places to locally get race fuel I don't think any of the 76 stations 
around here have pump 100 and ZERO stations have E-85. In fact, I would 
prefer E-85 over all the others, but there is only a single station here in 
California that sells it publicly and it is about 5 hours away. E-85 is less

than $2.25/gal whereas pump premium 91 is ~$3.80, racing 100 or higher is 
~$6.00/gal, and propane is ~$2.00/gal.

Hopefully I can keep this topic going. Everyone says that CNG/LPG injectors 
are special and costly, etc, but using more common gaslione injectors would 
be a great option for the amateur.
