- 1984 chevy 1ton 454ci running a full propane LPG fuel system. the "carb"/mixer is an IMPCO 425 and the regulator is a century 2504. the local hardware store sells the 1" pipe thread elbow and nipple. very easy install and runs great.
this is NOT a "dual" fuel carb.
Thank you for your effort to show this is possible, I have a 87 454 class a MH i am planning on converting you have shown me the path and I will walk it...
Ithink this video about LPG explained how LPG IS PRODUCED
Thinking about converting my 1986 c20 305 c,i.
Very cool.
Where did the vacuum line that controls the fuel lock off plum into? Both ends of it?
this system uses an electronic lock off vale.
What is your Regulator model ?
what MPG you get?
Hi I have the same setup on a 350. Howd you tune it?? I know there’s two screws on the front of the carb.
Hello Dear Friends,,, I am a owner of the 455 cui. Engine. It is working by “4-barrell Rochester QuadraJet carburetor” I own an American PONTIAC GRANDVILLE Car. I live in a wheelchair. There is something I want to learn from you, knowledgeable friends. I would be really happy if you could help me. What is the most appropriate "Propane Dual Fuel Mixer" Kit that should be installed on the 7.4 Liter (455 cubic inch) engine on my car, so that it works like it works with gasoline without any problems, and also shows smooth running performance in daily use? From whom do I learn about Brand and Model information? From whom can I get technical information? Who knows about this subject?? Could you please tell me which brand and model kit is the most suitable kit for this engine?? I am a good hearted person. because throughout my life, “my first priority has always been to help people”. And Now, on this issue, I am asking you very seriously, "BECAUSE I NEED YOUR HELP". because I'm sure of this; If you were in my place, and you asked me for help on a subject I know, I would definitely help the person in front of me, no matter who they are.
NOTE: I want to run my car on Propane, Yes.. BUT,
I just don't want to use only gasoline. I really need this car as I can't walk!!! If I run out of propane on the road, I HAVE TO "START THE ENGINE ON GASOLINE" and CONTINUE MY WAY.
I hope to hear your suggestions soon
Thank you very much for your helpfulness and sensitivity
God Bless You 🙏💙🙏
I cant log into my original account to answer questions.
this set up was simple after talking to nash fuels. it runs well but have never checked MPG.
to adjust it is simple, one idle mixture screw and main mixture screw/valve.
I really wish youtube would let me log back into this account:)
You still have this? Ever dyno it?
