Keep upper valve lube kit on it.

Good idea is to put a couple of clamps on the pcv hose, s@@t to get to but if they back fire will pop the hose off and wont idle much easier to put hose clamps on it when its cold rather on the side of the road when its hot.

If i didnt want the luggage space and under side clearance id do it to mine

mine is mounted on the other side of the underbody from the petrol tank, so the spare stays where it is and there is no loss of cargo area, and it's only a 60ltr tank so there's no loss of underbody clearance either, it's a win win situation.

Hi Guys

Resurecting this thread as I'm looking to install LPG on my Triton and am leaning toward mounting the tank underneath. Are ther any gotchas that I should be looking out for? Also what sort of fuel consumption are you guys getting out of them? Just trying to work out expected range from the tank.

The bloke that is quoting me reckons he can only fit a 53L tank in where the spare is but the risk of smacking the tank on the deck and the small capacity doesn't make that option so appealing. Xagtho's setup sounds sweet so I'm gonna chase up that option today.

Thanks folks

my tank is under the body aswell it is a win the only prob thats where the exhaust goes. the people that did mine just ran the exhaust under the tank so it was lowest point. not good. got that rectified now and it all good. will take some pics of install tomorrow to show

Swaddo, if you put your tank in place of your spare you could fit a 90ltr tank or bigger.

If you go for the small tank it can fit in the underbody on the opposite side from the petrol tank you just have to re-route the exhaust, the spare stays where it is, but you can only fit a 60 ltr tank, which is 53ltrs usable.

I only have the smaller tank in the underbody with the exhaust re-routed, it gives me an average range of about 300k per tank around town while pushing 33's, I would like it if it was a 1000ltr tank so I would only have to fuel up once a month, but in reality I can afford a couple more fuel ups per month for the price of running on lpg.

FYI, with todays lpg prices I average a running cost of about $9.20 - $9.60 per 100klms.

Thanks dig

I've had a chat with gas fitter near work and he happened to have 2 tritons in there (1 was his) so I was able to crawl around under them. I'm probably going to go with him. He also manages to tuck the tank(s) right up, and does the right thing with the exhast Smile

I'm also considering a dual tank system o boost my range if the cost isnt ridiculous

another question, anyone know anything about flexible lines? one of the other guys I was talking with made a big fuss about the fact the he runs flexible lines throughout

the flexible hose shouldnt be a prob it a 4wire braid hose. mine only uses that from the fill point to the tank the rest is all copper pipe

Thanks for all the info folks. I've got the beast booked in for Feb to get the system fitted. I decided to add 2 tanks under the tray so that I will have a usable range on LPG. With full fuel and LPG tanks I should have roughly 1000km range.

I'll post a few pics after it is done

Swaddo:
One thing to remember about gas is the possibility of engine backfire, resulting in a blown air cleaner housing and possibly the airflow meter. Expensive... Also you tend to pop off the crankcase PCV hoses, but in many ways that is better because that tends to limit the pressure rise elsewhere.

Backfires occur when the spark prefers to jump to another lead rather than the one which is due to be fired. Mistubishi, in their wisdom, run their High Tension leads very close to each other. Remember that the spark always takes the easiest path to earth. If the spark plug gap is too large the spark energy will find another easier way to earth. A bit of crud on the leads and if you are lucky it will short to earth, if you are unlucky it will jump to the next spark plug lead. If the inlet valve is open on that cylinder at that time, you get a backfire. The reason it is worse with the older style mixers is that you have a manifold full of volatile gas, whereas teh newer injected gas systems have much less volume of gas to explode. Result is a "Pop" instead of a "Bang", and believe me they do go bang, especially at full throttle. I speak from experience.

Keep your HT leads clean and as separated as possible. If possible, close the spark plug gap down slightly (to minimise the voltage needed to jump the plug gap) and you should have no problems.
