Additional guages :S

[whiskychaser]

Any one of those scan tools that use the OBD plug would certainly be the go
Any UK car manuf. before 2000 may have an OBDII plug but its hit and miss whether any of the functions work or not. I agree that there is no point in putting a vacuum gauge before the butteryfly
I think John's problem is that Jaguar software is bespoke (like Renault but not the same) and the support on Jaguar forums is perhaps not as good as on this site.
What does the exhaust sound like? Smooth or the odd 'dum..dum' (Dont laugh if you werent there. But you can laugh if you know what I mean)

Hey guys, first of all thanks for taking the time to help me out

Some conflicting advice there re the vacuum gauge - but SS my car has a supercharger so the boost gauge (if it works on that OBDII device!) will be useful to look at... And thanks for the info on the positioning of the mechanical gauge too as I might still invest in one.

It's funny that you mention the fuel filter as it's the first thing that came to my mind a while back - There's one sitting in my boot as I type! The roblem is when it came to changing it one of the connections will not come undone. I tried all the obvious things and still it was locked tight. I could easily break it off but it's on the connection to one of those long fuel pipes that look like a right pain to change! Now that you've mentioned it I'm tempted to have a go again today but I've also got valve cover issues to deal with!

You're not wrong there Colin, there's like three guys on there that keep it alive. They themselves are great but obviously they can't be there all the time! I actually thought of you the other day and checked the tailpipe for the dum dum as I remembered you saying!! Yes it does have one but it is sporadic...

If you have such a hard time on the fuel filter... get those bolts and washers in case you break this one. Soak those bolts with penetrating fluids. Take a look at new filter to see if the threads are normal direction.

You need to 'shock' that bolt to loosen up so give your wrench a whack with a hammer.

I have no idea what any of the above means sadly, it might as well be in a different language! As for your bolt issue, get one of these....

I got one for the suspension work on mine, I'm not sure how long it will last and I've never used any air tools for comparison but it seems pretty good, its really helped me with the front end work. I think if you use it a few times a year it will last a while. As long as you've got the clearance to get it in there you're laughing!

Haha if only it was that easy... I've tried the penetrating oil etc and it had none of it. I wouldn't be worried about breaking the connection if it wasn't an integral part of the fuel pipe - It's the pipe breaking that would cause me a headache!
Still, I'm probably going to attempt it once more over the easter break, see if I can catch a break (not literally hopefully!)

Hey that looks decent for the price! Won't help me on the fuel filter unfortunately as you can only attack it with an open ended spanner and it's awkward even with that

Hope the rebuild is coming along nicely!
