Title: Just finished my LPG conversion
Post by: JamesV6CDX on 26 November 2007, 18:11:46
Today I dragged Maria around shopping a bit. Found an Autogas place in Newport, picked up a few LPG bits and peices - Olives and unions.

Also stopped by the VX stealer and picked up some spark plugs, new sump pan, and some other bits.

Stopped at B&Q, picked up a hole saw.

Then out came the tools. First job, was to find a good place in the bumper for the filler. I chose quite low down, drivers side, near the back. It was the only place I could get the pipework in behind it.

So, first job was to drill a big gaping hole in my bumper! A little daunting, but was easy enough.

Then I fitted the filler (swine) and plumbed it into the tank.

After that, went along to BP, for the first attempt at filling with LPG. Connected up the gun, so far so good. Pressed in the button... and...... ahhhhhhh....  a lovely sound, she started filling with gas.

at 44p/litre, The tank took just under 68 litres, which cost me £30  ;D  8-)

Flicked back onto LPG, and the injectors fired in again. Ran absolutely fine back to Maria's.

So, new spark plugs are to go in tomorrow, and hopefully it'll be job done  :)

Oh, only one more thing, I need to adjust settings for the sender, because it was showing 3 lights when it ran out. But that's a 5 min job :y

The led fuel gauges are pretty crap tbh James......but three leds on is a bit too far out.

Mine usually does put the red led on before running out.....

Tho how i measure distance left is, i use the trip milometer......i know i can go 125miles about town or 200 on a motorway run.....  :y

In theory, but I will be sticking to the same service intervals.

Because LPG runs hotter, it actually shortens plug life..

Before I use an LPGd car..really service intervals interestingly become longer..And the oil remains clean .

IIRC the gauge was reading 3 bars when full too :-/

Have a play with the settings in the ECU, James. I suspect my guess at the sensor resistance was wrong ::)

.. and 68 litres :o

That tank's full to the brim or the pump's lying to you! Supposed to be 54 litres to 80% isn't it?

Just don't leave it out in the sun when it's full....

Glad to hear it's complete though. Best get the man to give it a once over ASAP.

Well done :y

I'd also give it a once over with the lap top to check the fuelling's still OK once the new plugs are in. We did have a rear multiram issue when it was first done.

Remember its a donut tank. underneath the boot floor.....it can only take 38L of LPG

How much has it cost in total? A nice break-down of costs would be brill  :y

Ahh, well, this particular issue was due to the pipe having "come adrift", while we were wrestling with the LPG wiring, no doubt ::). Judging by the whooshing noises coming from  it when underway I don't think there is another issue.

James already had the tank from a breaker. The kit from Jeremy contained everything we needed for the front end and fuel plumbing to the rear down to the last hose clip. We had to buy a union to connect it to James' tank, which is fair enough. He didn't supply the tank. That and a new LPG filler was about 50 quid from the local LPG guy.

The one thing I would do differently next time is to ditch the piggy back wiring for the petrol injectors and make up a plug and socket on the LPG loom to mate with the multi-way plug and socket behind the 2,4,6 bank, because it was a bit of a struggle fitting all the piggy back connectors under the plenum and there was miles of spare cable on the LPG kit loom.

I'll let James provide the grand total as I didn't pay it but suffice to say that the front end will only need pennies spending on it once you have the kit. Back end depends on choice of tank. Probably another 200-300 quid if you buy new.

Kevin

Cool...I bought a tank (and an older kit) a few weeks ago for £70. I might start installing that one until I get the newer setup.

Time to rob scrapyards of these connectors, lets check with all the breaking cars on here.

Good thinking, actually, or I wonder how much VX will sell the plug and socket for?

If we can get them with a few inches of loom either side I guess they could be grafted onto the LPG loom easily enough.

Went for another run last night. She's going well on gas, but still a slight misfire under heavy load, definately feels ignition related.

Just been outside in the piddling rain (I love it really) to change my spark plugs.

Observations are -

The plugs on the 1-3-5 bank (one of which we looked at, Kev) were all fine, and were probably changed as per the history.

But the plugs on the 2-4-6 bank  :o

Let's just say, while "servicable" under a petrol environment, I'm not sure they'd be much cop with LPG firing in the chamber.

So let's see if this makes a difference, I'll take it for a test blast shortly :)

That'll be the bank where they're slightly less easy to get to...  ::)

There was certainly one bank playing up because one of the Lambdas was consistently going lean during the misfire. I thought it was 1,3,5 but could easily have been 2,4,6. We've probably confused the 2 Lambda signals.

Maybe, the 67 litres that's written on the tank, is actually the capacity it will hold, rather than the tank capacity?

Failing that, something faulty that means it's not shutting off?

Just a thought, James. Is the manual fill level gauge on the tank working?

Electric gauge is not working (could be configuration) just wondering if the float lever is also supposed to close off the filler port at a certain level and it's not working...  :o

I'm sure I read on that tank "volume 68 litres fill capacity 54 litres".

Anyway, minor detail. Not a disaster even if it means the tank valve is fubar.

Kevin
Title: Re: Just finished my LPG conversion
Post by: JamesV6CDX on 27 November 2007, 14:59:50
I'll go double check.

Worst case scenario, is I'll have to just put 50 litres in at each fill.

The gauge on the tank is working fine  :-/

I'll pop out again and see what it reads on the tank!
Title: Re: Just finished my LPG conversion
Post by: JamesV6CDX on 27 November 2007, 15:04:06
On the tank it says:

LPG 54l Max Cap 80

Title: Re: Just finished my LPG conversion
Post by: Martin_1962 on 27 November 2007, 15:07:39
The tank gauge I think is pressure, the other is level.

Since you could fully fill it I would guess that the level float is sticking.
Title: Re: Just finished my LPG conversion
Post by: Martin_1962 on 27 November 2007, 15:08:26
80l and you put in 68l

You are fine then

I get 62-63 into a 70l at most
Title: Re: Just finished my LPG conversion
Post by: Kevin Wood on 27 November 2007, 15:08:35
Oh, that's not so bad then. If it's 80l volume it's filled to 85%

I would collect at least 5 sets and advertise them on the forum. This would make your conversion easier as well as the one after yours
