So ive decided to convert my Saab to Lpg. Never done it before but im a qualified mechanic, former master tech and for the last 9 years ive been a mechanical engineer so hopefully i should have enough skills!!

Im fitting a Stag 300-6, KME turbo gold, hana blue injectors and a 72l torodial tank.

Heres the progress so far:
Still to do is tank to reducer pipe, insulation on the pipework, wiring and leak checking then hopefully a bit of calibration.

It looks good, well done.
I do like where you fitted the filler, I can't stand ones cut into the rear wings.

Keep the pictures coming.

Forgot to update this!!
Ive added some fibreglass braiding thats impregnated with silicone to protect the lpg lines from heat and chaffing.
(Nobody likes chaffing now do they!!)

Whag i havent shown is the sleeving ive put on the faro pipe. Where it comes up onto the firewall and over the rear suspension into the tank is sleeved for the same reasons.

Heres where the fuel return feed is taken from. Ive utilised the test port which is a an-4 shcrader valve, into which the valve core has been removed and a grub screw placed with a 1mm hole and feed back to fuel tank. The 12v solenoid petrol valve is feed from the gas solenoids so it goes "closed loop" on petrol. So far no fault codes for pressure regulataion and it only dips 20kpag when the switchover occurs so not enough to cause a code to pop up.

Car has now covered 250ish miles (all town) and is averaging 17-18mpg (typically 19mpg on petrol) so not too bad a drop and ive already paid pack £30 of the cost, only £490 to go!!
Im rather impressed if i do say so myself though, switchover is seemless and there really isnt any loss in power.

Looks a good install, well done.
And I thought there was no room under the bonnet on my MG ZT until I saw yours.

Thanks, yeah its a little tight in there alright.
Next plan is a remap, posssibly a jzw one from the usa that will take it to 320bhp and 520nm!! Technically the reducer says it can deal with 360bhp but i dont like pushing components to their absolite limits so may have the map scaled back to 300ish.
