Thread: Update

Gas won't kill a D1 V8, they are well capable of doing 300 plus thousands of kays on gas. However you need to have the correct plugs and good leads fitted or it will probably backfire under load at the earliest opportunity. Basic conversion means a mixer ring fitted to the inlet, no fancy electronics and a gas tank ruining most of your cargo space. Search the forum for pics, there are various ways to do the job. Second hand is allowed too.

If you don't mind, could you name the good leads and plugs of which you speak??

Ignition leads:Bosch or Magnecor. I use the first all the time but others prefer the second.
Plugs: Bosch WR7DC+ (or their NGK equivalent), or Bosch LPG specific platinum WR7KI33S. Gap is important, should be 0.7mm/0.028".
Timing: should be set at 10 degrees BTDC for a standard engine on gas.
Petrol: you may need to run premium unleaded as it is not recommended to use ethanol-containing fuels in dual fuel cars. It goes off too fast and attracts moisture.

Thanks mate.

The Disco is almost due to go back to the gas installers for the first tune (1500 kms after gas went in), would you suggest changing the leads and plugs prior to, or after the tune??

Ask your gas installer what plugs/leads/timing he does, if he voilently disagrees with my recommendations then you need to do them afterwards.

If you are still using the original leads, yes, change them ASAP. Remove a plug and check its gap. If it's bigger than 0.7mm either adjust or replace as required. Only you will be in charge of these service items, the installer usually only checks mixtures and things like hose clamp security and gas leaks.

Ok, so am I right in thinking the main diff as far as I'll notice is the location of the gas tank?

Also, I have some surface rust on my roof which I am cleaning up but am aware that any touchup will be VERY obvious so, are there any options? Ie. Could I get some aluminum sheet and fatten it to the roof like defenders tend to do on the tops of the front wings?

Many thanks,

phil

Regular gas tanks are big cylinders, there are special design tanks that are better for getting stuff in your cargo area. The most popular tank is that from the Falcon wagons, called a manifold tank (or scuba tanks by those who don't know what a scuba tank is) and they lie flat on the floor. They are expensive but can be got second hand from some wreckers dismantling XA-EL ford wagons. The pic shows one installed in a forum members D1. It holds about 60 litres of LPG.

Your roof is steel, so ally sheet is not a good idea. Standard bog and paint will hide it until it can be welded properly by a crash repairer.

I have now got my gap at .6mm and 9 degrees BTDC - any issues?
