Smile My lpg installation on my 940 saloon

Firstly before I start on about my 20 month long LPG installation I want to thank two people, firstly my long suffering wife who has been confined to bed with terminal cancer for almost the last three years, that is why it has taken me so long to do it, at 75 and being her full time carer I've not had a lot of time to spend on it, just the odd hour or so now and then,
Plus needless to say there has been setbacks and mistakes made along the way,
Secondly I want to thank Dave Houston (Laird Scooby) who has been a invaluable source of help, freely giving his advice, Dave also repaired and altered the wiring harness for me, and made the aluminium adaptors for the injectors that you will see in the following photo's, I would not have done this without his help, (well maybe) Thank you Dave:
My installation consists of a used but almost new 70ltr Stako cylinder tank installed behind the rear seats, Now some will say how will I get at the in tank fuel pump, if needed, the Lpg tank is on brackets to its frame which can be easily undone to lift the tank out, the brackets are bolted through the wheel tubs with 50mm square washers behind the nuts to spread load bearing, I had to sit the car on level ground to set the tank at 30 degrees then finally secured it down with the straps.
I have fitted a new Tomasetto multivalve to the tank,
The reducer is a new Tomasetto Nordic XP,
The ECU is a LPGTECH 214,
I have used new Valtek type 30 gas injectors,
The pipework to and from the tank is 8mm Faro pipe, two reasons for this, at first I used copper piping but a schoolboy error saw me kinking it when going over the axle so I replaced it with the Faro which also allows me to disconnect it from the tank, should I ever need to remove it, plus its far easier to work with.
Another big mistake I made was when I went to fit the Valtek injectors, the front injector was fouling over the rubber hose going to the FPR, I gently took the bend out of the metal pipe just before it goes into the rubber hose, another schoolboy mistake, I found later I'd cracked the fuel rail causing a petrol leak, luckily Luke (360beast) provided me with another fuel rail, thanks Luke.
I then adapted the bracket for the Valteks to move them over thus avoiding the hose the the FPR, which I also renewed. (Iknow I need to cut that bolt down)
I ran the Faro pipe from the gas tank around the inside of the wheel arch then along under the car clipped every 400mm or less then ran the tank wiring along side it inside split trunking just for some protection.
With the petrol leak now cured and the LPG installation completed I booked the car in at CRD PERFORMANCE in Bolton who carried out the safety inspection which it passed without any issue's (in fact they commented that I'd made a good job of it) they then did the final setting up on their software and carried out further setting up/adjustments during their road test, they then put it on the UKLPG register, I've also notified my insurance and there is no extra cost, V5C/Logbook sent off to the DVLA to be changed to duel fuel.
I wanted to add comments below each photo, but being useless with computers did not manage it, the very last photo of the badge that will be fitted when I've cleaned the car.
Finally I just want to say I have not used the car much since it was completed due to my wife's illness, but my reason for doing the LPG installation was NOT for economy saving money on fuel, No it was done mainly has a hobby installation and to help take my mind of other issues,
