Thats to easy. So you don't use a mixer? Just a tube going over the top of the carb?
Propane?

In my experience.. that is a seriously odd system..
But I have been wrong a bunch of times...
One thing I do not like, Get an electric fuel pump. I cannot see anything good by blocking off the mechanical fuel pump and letting it build pressure..

Yep its pretty simple when you look at it.

Propane is pretty popular here there is even a $2000 government rebait to switch to it

Could you take a pic of what the mixer looks like on the inside?

OK brb but you will be disappointed
Been through my pics don't really have a good one this is the closest I can find it really is just a ring with a feed pipe if I recall.
If Shortly Forty's is in bits he may be able to post up a better pic, I would have to strip the air Cleaner off get a photo and it's Sunday

Well ok I had nothing better to do
that, depends on the vntage of the pump..

Lol that looks to simple. So that is your mixer? And you have no issues with performace issues using propane? One thing I do know is there is an air restrictor on top of the carb.

No air restrictor with my set up it really is that simple.
Their is a DYNO print out on page one of the 2F-ETI build thread see link in sig
Propane is great, cheap, only draw back is Range but I run Dual fuel so 80Ltrs Propane and 80Ltrs Gas is my max load. 80Ltrs=21Gal approx
Propane/Gas Switch and Propane gauge below

Wouldn't mind taking a look at your set-up when you get it together.
Are you anywhere near Cairns?

A common mod is to put a 't' (with a v/small branch) before and after the mech fuel pump to allow the pressure to bleed off
When running and injected system, it is best to put in a relay that switches between the injector, and a resistor of the same resistance as the injector. That way when running on propane the injector is not cycling dry (and wearing out) but the resistor fools the ecu so it doesnt think there is an injection fault
On mpi injection systems, they ussually have to start on petrol - the length of the manifold runner is too long to get a good propane flow - there is aussually a small elecronic box that starts on petrol then automatically switches over when started (normally triggered off oil pressure sender or alt output). This also has the advantage of lubricating and cycling the injectors on each start so they dont dry oput and seize up - likewise the fuel pump.
My system is almost identical - I did turn out approx 2mm out of the top to remove the restriction (vloume is now the sum of the two barrels). However, a slight vacuum below the restrictor helps suck in the propane and I'm not sure it was an imporvement overall - must find another original one so I can compare!
Very cool. I have been considering this also. So basically a regulator, tank, control unit and some solenoids. I like the idea of using your current carb. The kits listed for a V8 on gotpropane require a sq bore intake and replaces the carb. Not economical at $1250.00 plus. The picture of the air cleaner with the hose on top seems simple.

COuld you put the mixer under the carb?
