Re: Vaporizer temperature, contaminants, and separate thermostats

All propane is contaminated to a small amount with heavy ends. Take the specification for automotive propane in Canada. It specifies HD5 as 90% propane, 5% Butane, and 5% of other products. The last 5% are typically the items referred to as heavy ends. They are the small amounts of oil and contamina...

Re: Pros vsi

Also a possibility that the filter is also the split for the rail supply. Single hose in and double out.

Re: Pros vsi

Normally there are two. One at the entrance to the Liquid lockoff or somewhere in the line between the tank shut off and the lock off under the hood. The other will be in the vapour line coming out of the regulator going to the fuel rails where the injectors are mounted. The line should split to sen...

Re: Air line oiler as simple valve lubricator

It won't increase the blow torch affect. Typically this only happens once a seat is leaking. The one thing to watch for it the quantity of lube added. Too much and you may begin to build up a deposit on the intake valve stems eventually blocking air flow. That's why Flash Lube and Mystery oil from d...

Re: Pros vsi

Could use a few more details. What brand of equipment are you running? Is it injected or carbureted. If it's injection and a Prins system or similar it could be as easy as a dirty fuel filter. The key reason injected systems return to gasoline is the fuel rail pressure drops below a minimum pressure...

Re: Adding an elec. fuelpump to an Impco vaporizer+425 setup

Sorry, I can't remember the highest HP we ever achieved with a 425. I vaguely remember hitting 280 RW. I believe it was with a Dodge 440 but with a really aggressive rear end set up. Keep in mind all of our testing at our research center was strictly on OEM engines built in the 80's and 90's. Most o...

Re: Adding an elec. fuelpump to an Impco vaporizer+425 setup

For the lean mixtures, have you removed the fuel restriction plate in the 425. If you look in the vapour inlet of the mixer you will see a brass coloured plate with about a 3/4" hole. The plate can be removed just by hooking it and yanking it out. This will enlarge the vapour opening to about 1.125 ...

Re: Adding an elec. fuelpump to an Impco vaporizer+425 setup

I find this interesting as I can't see a pump fixing your pressure issue if vapour is getting in the line. As Frank stated a pump will not pump vapour. The sympton you are describing would indicate a loss of liquid to the vapourizer. This can happen a couple of ways. Fuel slosh or a faulty excess fl...

Re: Holidays

It's kind of hard to feel sorry for you Storm. On the Canadian prairies it is going to be -24C on Dec. 31 and the New Years day overnight is forecasted to be -30C. We all know global warming is a reality but I think some Canadian Prairie people wonder about that at this time of the year. Winnipeg, w...

Re: Modern setup vs. ancient factory propane specs on tractor

:lol: Your right. Finding a top oiler may be difficult. Most of the tractor or farm supply places new what they were prior to 1990 or so. There are still companies advertising these. Here's a link to one. http://www.ampcolubes.com/. The write up mentions Marvel Mystery oil which I am sure all the fa...

Re: Modern setup vs. ancient factory propane specs on tractor

Pretty neat sounding project. The engines in the first 7 decades of the century had valves of relatively soft materials compared to the time when lead free gas was introduced. Lead in the gas provided substantial protections against valve recession. Anyone converting in that time could usually expec...

Re: AEB wolf-n HEI wiring

OK. I used a translator program on the internet and translated the blue wire directions. The blue wire attached to the LPG wire coming from the switch. This would indicate 12 volts on the propane lockoff would signal the box to go to LPG timing.
