What LPG gas mixer for a 2F?

[bsmith123]

Been speaking with a installer of LPG systems in the UK. The guy said his system will work with the exception of finding a gas mixer that will work with the intake.

Said his first car was an FJ40 but he works on Land Rovers--well cant make a living working on 40s in the UK!

So does anyone know of the mixer he was talking about is there one specific for the 40?

Are you thinking about dual fuel or propane only. "Dual fuel" mixers (what I call carbs) sits between your carb and the air cleaner "propane only" replaces your carb but still require a base plate and butterfy(s) or throttle body.
30 years ago (God, I'm getting old) I ran a dual fuel system using an Impco system on my FJ40. It might have been on a 350 Holley however which has a larger air cleaner ring than the FJ40 carb. I think I still have the adapter but I'm not sure. When I put the SBC in I moved to a different Propane mixer which basically looked like a large air cleaner on the Holley.
So, if you are looking at dual fuel, find an adapter, probably from IMPCO that has the same diameter as your carb. I think my adapter was angled or offset so the either the propane carb sat more beside the gas carb vs. on top of it or the air cleaner did allowing everything to clear the hood. This may be what he is talking about. If you are looking at Propane only, you could put a Holly manifold adapter on your manifold and run possibly run just the Holly base plate. I don't know if I will have time to look in the next few days but if I do, I'll try to post some pics.
If you are not asking about the "Carb" you may be thinking of the device that changes the liquid propane to vapor by heating with your radiator water. That should be the same for most all vehicles.
The systems are really pretty simple, high pressure hose from the tank to a filter/on-off switch to liquid/vapor converter, to low pressure vapor hose to carb/mixer to baseplate/throttle plate/butterflies.

here in aus ive seen a few different setups fitted in dual fuel theres a mixer ring that goes ontop of the stock carb that is the most common (and worst setup aswell)

ive also seen a impco 300 fitted inside the air filter housing worked terrible due to having to fill the entire intake arm and inlet manifold with gas before it would start

then for straight lpg ive only seen my setups first was an adapter plate to a throttle body with a impco 200 mounted ontop and a pod filter as the only ait filter

then i swapped to a right angle intake adapter with a throttle body and a impco 225

then i swapped to a gas research mixer

Here's what he said
"The only problem is likely to be the gas mixer for the carburettor. I would have to look at the intake system and see what can be adapted to fit. It is unlikely that a specific mixer for this engine will be available off the shelf in the UK."



I guess from what I read this will be one of those pro/con situations
anyone got pics?
