I'm hoping the experience on here will help me with my next problem! Any suggestions welcome.

I'm trying to sort the fuel rail and I was wondering if you would be able to share your setups please. I was planning to use the Jag rail as the ST200 one is copmpletely the wrong shape for the Jag lower inlet. I was hoping to put this on backwards as this will put the rail inlet close to where the fuel pipes come through from the tunnel. I was also hoping to use the fuel pressure sensor on the other end of the rail to feed into the ECU or at the very least as a way of sealing the end of the rail. However, the sensor fouls on the coolant inlet pipe when it is on in my prefered orientation.

So the options that I can see are:
    1. I use the rail the way round that Jag intended and add 1m to the fuel pipe to run it past the exhaust (not overwhelmed with this option)
    2. Don't use this sensor and try to find another way of blocking the end of the rail
    3. Use a different rail (aftermarket, DIY etc)
    4. Something else I havent thought of
Do any of these line up with how you all have sorted this?

Use the fuel rail off a 2.1 XType, cheap simple and fits! I bought one recently for 7.50 including postage.

I’ve used a vw fuel filter that has the fpr built in. So pump to the filter. Filter to the fuel rail and the filter bleeds of back to the tank.

Thanks guys! I don't trust my welding for fuel grade joints so looks like I need the one from the 2.1V6. I take it the pimple with the black cover near the fuel in end doesn't foul on the underside of the inlet manifold? Or does this need modification?

Didn't foul on mine, was well clear of the manifold.
You can see it at the front in this photo

So the 2.1L rail I bought seems to be a different rail to the one you have and unfortunately it is too tall. It doesn't have the 45 degree bend near the inlet either, so definitely a different version. I wonder if they changed it with the newer engine, so there are 2 different versions of the 2.1L rail and I have the wrong one.

On another issue, do any of you have a source of electrical terminals for the sensors? I am making my own loom so need to get new ones. Even if I reuse the exisiting loom all of the clips on the injector connectors are broken so will need to replace these as a minimum.

I have the Pierberg CWA200 which I am currently fitting and planning the hose routing. However, I am struggling with the connectors. The AJ30 (and by chance my MX5 compatable rad too) is 32mm, but the pump is 40mm. I cannot find an off the shelf adapter or useful existing pipe, so I am about to see if I can find someone with a lathe. I like the idea of a lathe, but I think it more than my garage and my wife have the capacity for...

Th only option I have found is a 1.6 1971 to 1980 Ford Escort which has 32mm one end and 40mm the other, but with the bends on it this pre-made hose may not be feasable for my layout. I have one on order so I can see if I can cut it up to use as an adapter. Failing that I was wondering how you Pierberg users overcame this obsicle? I have tried to hunt around the photos on here but as ever there is never the one photo that you are after.

Any help gratefully apreciated.

Ah thank you! So the 38mm has enough stretch to do 40mm, that does make sense. I have never actually worked with silicone pipework, this project is a steeper learning curve than expected! Glad I have your knowledge to refer to or I would never get the car finished.
