Hey all,

I have an LPG system in my Magna and want to get an idea of how hard it is to remove, and how much a second hand system is worth?

Note this isn't an EOI, just trying to gauge if it's worth removing.

For reference it's an in tyre well system

Not that difficult, really.

Is it an older style that you're thinking of updating? Or is it just knackered? Or are you wanting to keep it intact to sell on?

If it's an older system, it wouldn't be worth selling it as they only cost around $500 - $700 new, when rebates are taken into account. Plus they'll come with a 50,000km warranty.

It's about 4 months old and due to an untraceable electrical problem it causes the car to backfire under load, so I want to remove it, sell it for whatever I can get for it and then sell the car separately.

I've bought a Legnum so I'm really not interested in trying to get the issue resolved, I wondered if it'd be worth more separating them.

Well it depends which type of system it is whether it's worth selling it or not.

Vapour injection or mixer type?

Vapour injection I'm *guessing*. It has a hose that leads off to an inlet attached to the throttle body which sprays the LPG in along with the air?

I'm listing the car up here cheap as is, if someone wants to buy the car and get it sorted they're welcome :)

TY for the info but I think it's probably not going to make a lot of difference!

Gday,

Sounds like you have the mixer system to me. Vapour injection has individual ports which inject gas into each cylinder. Mixer puts a gas mixture into the air intake and combusts it when the mixture reaches the cylinders.

I have heard these systems can have backfire problems.

That said, a mixer system will be relatively easier to remove than a vapour injection system.

Very true. Once the gas is disconnected, the rest just unbolts off.

You will need replacement parts, however. The plate around the filler nozzles & the rear tube/pipe running from the TB to the AFM spring to mind straight away.
