Yep, definitely multi-point. I have an OMVL system on my 98 4.0l and it has been faultless for 4 years / 60k miles

I agree. I had Single Point on my XJ...... was good but it would stall and it did backfire.
The WJ I have now is on multipoint and it's flawless.

Multipoint again, but if cost is no issue, I'm running single on an i6 zj with no issues (did have to replace the air box when I first got it due to a back fire from previous owner)

I don’t run LPG, so I’m not sure if its standard practice these days, but I recall recently seeing a single point system which had a couple of one way flap type valves fitted to the air-box to allow the gasses to escape in the event of a blow back rather than splitting the air-box.

Yeah I've seen them. I fitted an induction kit instead, so if it does go again it'll just pop the air filter off (note to self not to run out of lpg)

My 1999 4.7 V8 has done 130k and had a OMVL  multi point fitted since 30k.It goes just great ,I really can't tell any difference between LPG and petrol except the cost of coarse.
