Lpg injector adapters

[Gaffers]

The good Mr Kevin Wood switched me on to a product which allowed engines like the Jag straight 6 lump to have lpg fitted without drilling the manifold.  Unfortunately the business has stopped making them due to lack on interest.  An inernet search since has found these:

The seller is unsure if they will fit.  Can the community help?  I doubt I will get any answer off any of the jag forums which are so slow to move I think most members are asleep under their flap-caps.

No experience obviously, but I would think they would space to injectors too far away for the standard locking mechanism to work. They must add a good 7 or 8mm to the depth of the standard injector?

...unless those horseshoe shapes in the pic take that into account?


Nice idea though.

It would require fabricating a bracket to allow for the fit.  My question is about the diameter and the fit of the petrol injectors, the rest I can make work

So we want injector diameters for a Jeeeeaaaaaag.


Out of interest, is drilling a problem? Is the manifold plastic, or space issues?

Teilo offered something similar, and I'm sure we said it as more of a quick fix, rather than an ideal solution

Haven't we still got a set of 6 knocking about somewhere

Although I agree... Not an ideal solution as it will compromise petrol injector placement too

It's Jaaaaaaaaaaaaaaaag..... please.....

I was interested in the product as it eliminated disturbing the inlet

Do I recall correctly that they are very temperamental when disturbed?

I'll have a look around and see if I still have the set that we had but I fear they were returned (eventually)

I'll have a looksie, it was me he sent them to, so I may still have them...

.. and "disturbing the inlet" looks to be a right pain in the brown-eye! 

Had forgotten we had some. Will check just in case they ended up in my LPG junk box.

I'm pretty sure 14mm is the size of recess into which a standard Bosch injector fits. A couple I've got here measure about 13.5 on the injector shank. Add a bit for the O ring to sit in, and you're pretty much there so from that perspective I reckon it'll be OK unless the injectors are something exotic. It's always going to be a bit "suck it and see", though.

I'm sure they came to me and I returned them to him

I still think they're going to disturb the petrol flow, which matters if you are intending to use petrol at high usage

[Kevin Wood]

If there is any shrouding of the petrol injectors I reckon it'll be at cold start and light load. There'll be too much air flow for it to make any odds at full chat.

I'd certainly give them a try before removing supercharger drive, supercharger, charge cooler, and the plethora of plumbing attached to it, which looks like it'd need an engine hoist to shift it anyway.

Ahhh... Did some muppet put all that in the way?

I might make a quick phone call to the fitter who did D's car tomorrow if I get a chance... I'm sure he's done a few SC Jaaaagggggs
