air hoses sucktion 4.2 EFI

[Clunk]

There was definitely one there on my old 4.2 efi.... but I dont have it anymore so cant take a photo for you. Are you on straight petrol or dual fuel?

dual fuel. looking at taking the LPG out cause its old, leaks and tank expired. I have been reading up on LPG Injection.

What you are saying is that that hose thats about 300mm long goes to the intake side of the air box because the other short hose goes to the bottom half of the air box after the air cleaner.

Are you having any misfiring or any issues of any sort along those lines?!

Line may be unused from LPG conversion onwards.

Plug the open end of that hose and see what happens(whether you hear a change in idling or something).

Well the engine now runs well since I did the tappets. Before that It ran on 5 cylinders at Idle. now runs on 6 at idle. But I am going to take out the LPG mixer.
then I should get better fuel consumtion. I hope. Does anyone use lpg injection.

What's removing LPG mixer has to do with fuel consumption?
What is your fuel consumption right now?
Not many GQs out there with LPG injection, as most of them have been converted to LPG before LPG injection became widespread.

If you don't notice any difference in engine's smooth running with the hose plugged, keep it plugged until you find out where it joins.

this the part that a hose attached at the base and connects to the air box. The other hose out the top goes where? Thats my problem for now. HELP.

@kbchez, the bottom part of that hose goes to the round tube from the airbox that goes into the guard, the nipple will be on top or if like mine has broken of and you will if your lucky just see a tine hole there

Thank you

If it has a lump of glue there I'd say it has broken before and its been glued on and broken of again, you will probably find the plastic nipple still stuck in the end of the long hose........ same as mine

[kbchez]

Thank you all for your great input. This problem solved.

What did you do to fix it as mines broken off too..
