I dont think its too difficult to solder up a circuit to switch over to wvo when a certain temp is seen at the senor, then the system would be automatic
You would still need the manual overide too,in case tank 1 or 2 was empty oh yes i've done that one i have my old twin tank system in the garage if anybody wants it 50 3-way 12v solenoids Wiring diagram , but i have switches the grounds instead of switching the 12v . VEG POWER IS THE FURURE
Im sort of tempted by wvo too, how have you dealt with the acidic issue, teflon fuel lines? new seals etc?
With a Twin Tank set up the system is flushed through when you switch to Diesel on start up and Finish. The Only seals uprated were the one in the Injection Pump
I'm using the o.e. fuel filter for both fuels and have the heat exchanger pre fuel feed solenoid on the wvo side only...diesel feed and return are in a closed loop arrangement Fuel filter changes will be reduced to 5k miles
I think I'm going to buy an lpg kit first and see how that effects effency. I'm due a tip end rebuild due to the mileage anyway so it seems wise to do it then.
I'm thinking about the LPG option too, but I need to look for places to mount the tank first. I don't want it inside the car really. The other issue, is that it's quite a big outlay and effort, for what's supposed to be a cheap, low maintenance car.
Fit the injection system required and just use a Calor gas bottle to supply the LPG until you happy with the results, then outlay the cash for a Tank to suit your needs. Remember your only using 20% LPG 25000btu so a 5kg Propane bottle will last a long time and the Vapouriser only cost me 30 Camping bottle set up http://www.mrsharkey.com/lpg2 remember this kit was fitted to a VW Rabbit 1.6L NA Expensive Kit US (EBAY do a similar one for 179 plus 35postage) http://www.xtremediesel.com/atstorquepro2000propaneinjectionsystem2.aspx
When you say it like that it sounds much more cost effective, I'm currently doing an lpg fitters course anyway so il be qualified to fit them and sign then off soon
Well if I can find a cheap enough kit (I have just been made redundant so cash is tight for the moment) I am willing to install and calibrate an LPG kit on the golf and confirm mpg savings and bhp improvements.
Good luck with your new career Dubnutter! 2 of the last 3 companies I worked for had to close down, so i know what it's like. Be interesting to see your efficiency and performance figures after your instal :-)
Sorry to hear about your redundancy mate... How long is the course? I did an 'alternative fuels' course many moons ago through ford as I was heavily involved with lpg transits...might have to make a call to see what that covers me for

Cheers guys, I'm 26 and worked at various autofactors since I left school so iv been heavily involved with cars, plus I'm a keen amature mechanic. So I'm pushing on with my personal trainer career! I'm doing the course more for my own info as I have always been keen on lpg, and a fair few people around me have lpg cars so it's handy to be able to maintain them. How do you go about establishing how much lpg to feed at what rpm and so on? Could a petrol ecu be used to calibrate with lambda sensor?
The ford system had its own ecu that piggy backed the o.e. ecu wiring and used all the inputs etc to come up with a multiplicative value for the gas stepper motor on the distribution manifold...the incoming gas was regulated by the heated evaporator which was linked to the inlet manifold vacuum
it all works on intake vacum , so the set up is on the vaopurisor and the adjustment is to the % of LPG to Diesel but there is a calculation table on the website below http://www.mrsharkey.com/lpg5
