LPG removal
My V40 BiFuel is nearing it's economical life end.
It needs and engine (burning oil) and the gearbox has a constant grumble (final drive bearings) and the ITV (MOT) is due. Now I have a Motorhome under renovation (diesel) but has Propane/Butane gas bottles on board. I was considering removing the tank and filler from the V40 and maybe bolting it to the underside of the MH and doing away with the bottles and then i can refill the tank on the road, saving a bob or two. My gas bottles aren't interchangeable outside of Spain and Portugal, whereas top up available anywhere. Technically I can do it, my Vehicle Technical card (Fiche Tecnica) say I have gas supply on board but doesn't specify where or for what for. My question is: In the tank mounted control box, does that reduce the liquid to a gas before it gets to the gizmo with the stepper motor mounted on it (gas distributor?) or is it liquid up to the distributor? If it's gas from the tank then i'm onto a winner. Looking at UTube for LPG fitments they all use oblong tank kits with additional gas valve to produce the gas from the liquid. Is the VOLVO one "built in"? Just an idea......cos the car will probably go for scrap. PS: Is it worth nicking the gas gauge out of the dash too?

OK so no one knows!!
Anyone got a components list for the VOLVO BiFuel? WHERE is the vapouriser? Where it turns LPG into 38mBar gas? On the tank or at the distributor?

Wrong kind of tank, you will need a vapour take off type tank

I would say a gas tank is a gas tank, it's the fittings that are different. I can't use the car vapouriser but a remote gas bottle type vaporiser as used by Gas-it for refillable bottles or the gas conversion fitters (as seen on U tube).
There is an ideal gap for the tank up between the chassis rails at the front of the MH.

gas tank is not a gas tank
Car tank takes liquid, camper tank takes vapour Step away before the blow someone up and I am not joking. Keeping an eye out for newspaper headline now |

I have been in a stack of LPG vehicles. Not one ever worked reliably, usual was engine management lights, spluttering under full throttle etc etc. Less usual was burnt out valves and engine issues at low miles (less usual but not rare).
Junk it. Its just not worth the hassle. Now, if you can buy a professionally equipped one that actually works granted maybe. |

classicswede: All gas bottles (home/vehicle) take fuel in liquid form. See the Gas It website where they sell a kit to refill household gas bottles at a fuel station in MH's.
There are plenty of videos on UTube showing gas installation on campers etc for heating/cooking. All of those installations have a chassis mounted gas vapouriser mounted near to the tank. I have found the vapouriser on my V40 and as said previously it's not suitable. So for my MH it's a round VOLVO tank instead of a gas bottle shoved into a cupboard behind my seat! XC90Mk1: My V40 BiFuel is nudging 240k miles. The only reason i am junking it is because it's now consuming a bit of oil (because some spark plug ceramic fell into a bore and I couldn't get it out) and the diff. is noisy requiring a gearbox. Apart from a stutter at exactly 1500 rpm on gas (a nuisance but not grief) it has never missed a beat, ran forever on Denso single point plugs at £10 for 4! Cost me £100 in fuel to get from southern Spain to the UK each way. My diesel Kangoo couldn't match that. All on a car I bought for £600 6 years ago. I've had my monies worth out of it. Replacement is a Skoda diesel.

The difference between an automotive tank and a camper tank is simply the position of the gas take off pipe.
I've seen motorhomes fitted with 4 hole tanks and two take off pipes, one for the engine, and one for the cooker. In an automotive tank the takeoff pipe takes liquid from the bottom of the tank. In a camper tank, the takeoff pipe takes vapour from the top of the tank. There also needs to be some extra apparatus to trap any liquid coming out of the pipe if the tank is shaken around, and a pressure regulator (which is probably what you are referring to as a vaporizer). If the Volvo tank is a single hole tank, then you're stuffed, as I don't think you'll find a multivalve with a vapour take off. If you're reusing an old tank (over 10 years old), then it will need to be inspected and pressure tested with a certificate to prove this, or you'll invalidate the insurance on your motorhome. By the time you've found someone to do this, and then bought the new valves and fittings for vapour take off, you'll have spent most of the cost of a new tank. So it's only a job to consider for the people who are terminally cheap, or don't care about the safety of themselves and/or others. |

pinballdave: At last someone with a definitive explanation. I've not looked as to the VOLVO LPG arrangement. Neither have I looked at an after market LPG installation on a camper that JUST feeds the camper internals and not the engine too.
Surely a liquid filled LPG bottle is still running thru a pressure regulator reducing liquid to a gas no matter how much is in there. Granted the regulator is always at the top of the bottle, hence what you say, needs to be at the top of the tank. So to put your mind at rest, on second thoughts, it aint worth the stress. I've room for 2 bottles on the side of the MH and they will probably last forever.....without spending £500 on a GasIt conversion to save 25 every 6 months! Anybody want some BiFuel parts before it goes to the scrappy?
