What's that plug under the heater hoses by the the drivers side rocker cover? Lpg related? I can't see the lpg ecu anywhere! I wonder if it's on the other side of the bulkhead behind the glove box?

See you must have a leaking throttle body heater judging by the bypass in the last photo.

That's the 2 hoses to the cabin heater and where the vapouriser/s normally get coolant fromSee you must have a leaking throttle body heater judging by the bypass in the last photo.

So it was larger diameter? You still have the TBH pipes connected? Next job check TBH for drips, could be your slight leak.I know what you mean, but when i took my vapourisers off, i put that same U in place.. not the exact same one

I did wonder about that plug too as it didn't look standard. I will have to trace the wire back, the wire from the dash indicator disappears off to the left so it would make sense that is in behind the glove box.

Are we talking about the same image?So it was larger diameter? You still have the TBH pipes connected? Next job check TBH for drips, could be your slight leak.
You can just see the side of the brake fluid reservoir...

Yup the U shaped pipe joining the flow and return, usually that size to the TBH.

We have a kia that is lpg and when we got it the vaporizer was leaking. We couldn't get spares for it so just replaced it with a similar one from lpgshop.co.uk for about £40. Very helpful people, will point you in the right direction and let you choose which one, not try and push the most expensive ones your way.

The guys at Tinley are extremely helpful.
I recently bought an evaporator gasket set, replacement LPG fuel solenoid, fuel filter and a couple of other bits'n'bobs.
I'm no mechanic by any stretch of the imagination, but with an engineering-competant friend looking over my shoulder encouraging - more like barking orders - at me, I managed to get my BRC LPG system running much better.
There is also Autogas 2000 Leisure Ltd at Thirsk 01845-523213. Ask for Jon..he is also very helpful.
Good luck...I'm sure you'll be chuffed to get your LPG up and running. It'll be like getting a rebate from HMRC every time you fill up at 73p/ltr or thereabouts....

I can't understand why the inlet & outlet coolant pipes are linked using the "U-shaped" pipe? I suspect it could be an ideal place for unwanted air to possibly accumulate in the system.Yup the U shaped pipe joining the flow and return, usually that size to the TBH.

It's a work around if the throttle body heater starts leaking.the flow and return pipes usually fit there Mike

On my BRC installation, those "tees" are where the coolant pipes feed my evaporator. If that was my car, the evaporator would not be heated at all. The feed for my throttle body heater is nowhere near where that U-bend / bypass is.

The LPG ECU is housed in what I understand to be a custom battery box on my BRC installation.

Well I have traced the cables and they disappeared into the main loom which seemed a bit odd. Anyway after some poking about I found the lpg ecu. It turns out it is a swap out for the original bosch ecu and it lives ironically in the ecu box behind the battery. Who would have thought that it was hiding in plain sight.
