Thank you, definitely different then. I wonder if I can do anything with this one or if I've wasted £40.

If nothing else it will get you up and running until you find one.

Yes, it will allow me to wait till there is one at a good price. It still may be a good idea to reduce the power, stop me stuffing it into the first tree I try to go round. Or maybe not.

Right, I got me an ST24 inlet manifold to be getting on with, an ST220 throttle body and some 15mm aluminium plate to make some spacers out of. I offered up the Jag fuel rail but it's too tall - I'd need to make the spacer about 20mm. What fuel rails are you guys using? The ST220 and ST200 ones both look a bit lower profile.

Cheers,
Ben

Standard AJ30 fuel rail on mine,with all the standard crap cut off the ends and AN6 fittings welded on.

ST220 injectors are at a different angle to AJ30,hence why a ST220 lower inlet wont fit.

What makes you say AJ30 rail wont fit?

There must be different versions of the aj30 fuel rail as mine is plastic?

Aye, mine is also plastic! Although that would now explain why it doesn't fit
Looks like a new fuel rail is on the cards!

Aye, looks like. Or you could swap to a different fuel rail, which is what I'm planning on doing as cutting out even 15mm thickness is a PITA!

Oh yeah just looked on ebay,the plastic fuel rail lower inlet is quite different to the one with a metal fuel rail.

I think you will need to get one with a metal rail to work with the ST200 upper.

On the top of the metal rail I've cut the pipe inlet off flat with the rail,then welded AN fittings on the ends.
On the rear of the rail under the TB I've had to extend the rail with some steel pipe and angle it down so the rail exits under the TB.

Mine is the plastic lower, but I used the 2litre fuel rail because it's dead ended.

Mines got plastic lower manifold,but not plastic fuel rail

Also the gasket set up/seals are different looking at pics,mine with the steel fuel rail uses oval O rings to seal to head and also the upper,the plastic fuel rail set up uses gaskets by the looks of it.

This is what I have.

Seems to be the early engines had this set up then 01 onwards have the steel rail. This uses gaskets rather than the oval o rings.

Dave was yours the same as this? And you used the 2.0 v6 one? A straight swap I take it with injector fitment/angles etc?

In fact looking on the bigger screen on the laptop looks like its going to have to be a full lower manifold change. Ffs. Hope the injectors are all the same as I've had these overhauled.

Cheers Dave. I dont know if its camera angles or if the lower manifold with the steel rail looks thinner? than the one with the plastic rail aswell.

The steel rail is thinner and much lower profile.

Have just offered up the inlet (with fuel rail removed) and I'm still probably a 25mm spacer short.

Having seen the pics of kevs build up his lower inlet looks a bit thicker. Have measured up the lower inlet and I have a depth of around 47mm. If anyone has the type of lower manifold with the metal fuel rail could you by any chance measure its thickness to compare?

I have just measured my spacer and it is 30mm, that gives me 30mm clearance to the highest part of the steel fuel rail
from the manifold. So a 15mm spacer would give 15mm clearance.
I will see if I can measure the lower inlet. my engine is a 2001.

As near as I can tell the lower manifold is 50mm high.
