Lpg Liquid Injection - Part 1

One thing I recently found out is that these systems need servicing at least every 12 months or 15,000 kms.

They are not like the old time systems these have 2 filters that need to be replaced otherwise
the flow to the injectors gets restricted & with low flow, when the pressure pressure drops the system will
automatically cut out & switch back over to petrol whenever you give it much throttle.

You can buy both filters & seal kits shown in this video on ebay for around $30 delivered.

I thought this video was quite well done :goodjob:

Amazing how much gunk I get in our VE dual fueler, lots of black crap.

Change every 30000kms at 15000 it was cleanish

Yeah I never knew they even had any serviceable filters
that needed regular changes until I started looking for a reason a car that
feels like it's running out of pressure under throttle & keeps cutting out
of gas & switching itself back over to petrol all the time.

I never even thought that there could be that much gunk in the gas.

I just thought it was worth posting on here so other people know.:cheers:

All these systems seem to use the same size filter

what the guy on the video said about his V8 using more fuel & the filter clogs quicker makes sense.

Always been loads of Crap in LPG, typically a yellow waxy gloop that coats everything..

I get service reminder every year from my installer and have been ignoring it
Thanks for the heads up
I recall mixers getting waxed up in the old days

Yeah, it was something I never knew before, I just took all the old systems for granted.
When I started troubleshooting the problem with mine I stumbled across that video & it all made sense.

Well here is a couple of pictures of the filters I removed from mine today.

The liquid filter

& the vapor filter.

As I posted before they are exactly the same filters as you see in the youtube vid so you can see how filthy mine were.

Wow that's a mess

The JTG liquid injection system I have uses an inline filter between the fill point and tank, and an in tank filter. Originally the in tank filter was supposed to be changed every so often, but that requirement has been dropped. last time I had the system looked at they found that the original installation place had not even put in an in line filter! That business was sold so I had no recourse to them. I may just do it myself from now on the make sure.

I have a JTG liquid system too. I looked under the bonnet the other day and couldn't see any filters anywhere. I may have to drop it back to A.P. S to see if it needs new filters..

Hey let us know how you go mate.

Perhaps even just phone them & ask?

Pretty sure you will find they have filters on any later model car with injected gas.

Will do mate.

Should have the inline filter and intake one. My aps system did.

Do you need to be a registtered LPG installer to change these filters?
