LPG Discussion Forum

Hello,

No this on my '97 Range Rover P38 4.6 V8.

I have access to an emissions tester and was just checking it on petrol and to LPG to just check what it was like on LPG and that when I saw the difference.

The calibration is pretty good, injector times and short term fuel trims remain steady no ...

Spark plugs are old so maybe it's that!

Would closing the gap a bit help??

Hello All,

I have just had my emissions tested and I have a sizeable difference in the HC reading when on petrol and when on LPG.

The LPG HC reading is much higher. The car runs fine on both LPG and Petrol, and the emissions are well under the threashold for a U.K. MOT emissions test on petrol, it ...

Time to close this thread out!

I've spent most of the day at Tinley Tech with one of their guys testing and probing. It looks like it was the ECU holding injector output F and maybe G to earth causing the injector coil to burn out. The faulty ECU was applying full alternator voltage as soon as the ...

New rail arrived and fitted. Same error!

The new rail was getting hot to the touch, so I've switched off.

I've now probed the injector connections, and it looks like injectors F and G are being held open. I'm reading a steady voltage of 14.4v for injector F and almost the same for injector G!

I ...

Right,

I've done some tests, the fault stays with the injector as soon as you move the connection.

I was going to move the whole rail to test it on some other cylinders, but when I touched the casing to the injector it was red hot and burnt my finger.

Looks like a faulty injector to me. I've ...

Thanks for the reply.

The fault only logs when running on gas. When on petrol it all looks good, with no injectors showing "X".

I connected all the bank 2 injectors (positive included) at the rear of the engine because that's where I had best access. If the positive connection did cause a problem ...

Morning All,

I've finished the installation, I'm pretty happy with it too. Certainly the best one I've done in terms of neatness, and technical problem solving.

Except for one thing.... it doesn't work.

The kit is an AEB V10 kit from Tinley Tech with "i-Plus" injectors. When switched on it won't ...

7.5 is the threshold. As mine is a class C RV I'm well inside that. People do replate class A RVs to get them under 7.5 tonnes. I probably would have done that if I'd bought one!

its a 2015 Winnebago 31H, but the running gear is a Ford E450 Superduty with the 6.8 litre V10.

A huge engine, AND sluggish! But it does weigh 6.5 tonnes when full. I've imported it myself from the US and I'm just waiting for my IVA test next week. I bought it nearly new and I'm pretty sure the ...

I have had it on my OBD reader. I don't remember seeing a fuel pressure reading, I also don't think I can see a pressure sensor... How does that work when the LPG is running then? Does the fuel pump just keep pumping away? I'd have thought that that's a bad thing?

I went with a V10 AEB kit from ...

Hello again,

Apologies for resurrecting such an ancient thread, by I have at last bought my kit and started the conversion. Life got in the way there for a while...

I'm just looking at where to site things generally and one thing I noticed is there doesn't seem to be a fuel return line for the ...

I should like to see pictures of the V12 conversion!

Single 10 cylinder system it is then, thanks for the advice.

Are there any pitfalls to fitting two tanks? I'd like to have a filler on each side too, so I can go to either side of the pump. Is it just careful plumbing and non return valves, or ...

Dear All,

I'm thinking of converting a nearly new petrol powered RV to run on LPG. The engine is a Ford Triton V10 producing 362HP.

I'd be doing the conversion myself (my 3rd), and have just been looking about for ideas.

I'd be very interested to know the forum's thoughts on what kit to go for ...

Cheers Tubbs.

Do I need to replace them, or can they be disassembled and cleaned?

There's one in the multivalve, and one at the reducer end isn't there?

Hello,

I have a BiGas sequential system fitted to my P38 Range Rover 4.6.

It has been perfect since the system was installed about 18 months ago, however I now have an occasional problem.

Sometimes, after filling up, 2-3 miles down the road the system beeps and changes over to petrol, as if it ...

I have made some scientific measurements with my iPhone stopwatch and a BP pump.

Emer multivale, and Faro polypipe.

I too am getting a litre in just under 3 seconds. 2.5 at the start of the fill in fact, so not bad at all.

Certainly fast enough not to worry about.

Tubbs wrote:...Emer valve with poly. A litre in just under 3 seconds. What exactly is wrong with that ?

I have to say I'm not bothered about the speed of the fill. It is plenty fast enough.

It's the reduced quantity I'm worried about. It knocks 25 miles off my range!

Well,

I've had my polypipe in place now for a few weeks. It is a bit slower to fill (I don't have exact times I'm afraid) not more than a minute (longer than it used to) on 70litres I wouldn't have thought, but I'm not getting as much in as I used to.

I'm getting about 6 litres less in the tank ...

I didn't move it far!

Probably my head to be honest, it does that a lot.
