Welding and LPG conversions

[Luxobarges_Are_Us]

My Granada has slightly crusty wheelarches- what a fucking surprise! However, they are not about to disintegrate within the next five minutes.

 

Will an LPG conversion (the filler being about 20cm from the arch and going into the tank in the boot) make it impossible to weld without taking the whole car apart? Was planning on getting it sorted, but I've just been quoted £350, and I am not too keen to spend that sort of cash (was thinking it was going to be about half that).

I had a squeaky bum when I ground off the exhaust clamp on the meriva, right next to the plastic tank. Can offer no advice but I'd be pretty careful with it...

As i understand, the LPG tank has valves so pipes can be removed to isolate certain parts of the car.

 

Take some advice from the LPG forum - I found them very helpful

Bloke up road sent his landy off to have major chassis welding, told them it was lpg and off he toddled

 

They since rang up saying that they had to get a registered lpg installer to remove it and will need him to refit and certificate after theyv'e finished

That might of been near the boot floor.

Cheers for that! Quite a bit of food for thought there...

Can you not have a round tank in the spare wheel well in the boot floor ,or somewhere else with the filler internal to the car,so that there is no cutting of bodypanels required ?

The tank will indeed go into the wheel well. Internal filler sounds like an interesting idea- I'm off to google to see some examples of it.

IIRC the filler HAS to be external, probably because of ventilation issues.

That's what I read, too. May be able to get away with sticking it on the rear valance instead of the wing, mind.

Correct. The tank also has a vent system which must vent to the outside.

 

As for welding, the tank should have a manual shutoff on the filler multivalve on the tanks so that can be closed off and then the filler point and pipe could be removed if you like. All electrical valves default to closed when unpowered so disconnecting the battery will disable all that. I would also run the tank dry before starting work on the car.

 

Personally, I don't see it as being any worse than petrol when working on a car.

You are correct about the valves.

 

The filler has to be outside, as you said, and there are rules about it's position in relation to the exhaust. Mine is the opposite side from the exhaust. Some cars have it in the middle of the rear 'cos they got pipes either side.
