Does anyone on here have the above system, i have a question about the fuel/air intake manifold.

Don't have one but ask away... Some of us do have a little LPG experience and may well be able to help!

Okay, i have a collar that sits between the throttle body and the black air intake pipe from the MAF/Air filter. The LPG pipe unions on to this collar. The collar sits on top of the throttle body but there is no gasket to prevent air leaks between the throttle body and the collar, its just held on by three allen screws. So much so you can hear the air sucking when you blip the throttle, does this sound right??
I wouldn't have thought there should be any air leaks on the intake at all...

Doesn't sound perfect to me. My mixer system on my RR had RTV sealant between the plate and the throttle body but be sure it has cured before starting the engine!

Sounds well wrong! The readings from the MAF will be all over the place due to the extra air getting sucked in.

As i suspected then....
Should i get the Vaux black sealant (same stuff for cam covers) and give it a good sealing?? Or some other stuff?

And thank you all, you've been fantastic as always.
