Brilliant. The schematic was very helpful I plan to laminate a copy and nail to the underside of the bonnet.

I removed the pipe and yes there was a little bit of pressure , but not a lot. Just a few second's worth. Is that good or bad ? I have just run the system with the digit over the outlet. There was some pressure but not rather less than direct from the pump. Does that tell us anything ? Can one define good pressure ? I am now running with the door open to see if anything happens, just in case that pipe was not well seated.

If the pressure out of the tank port is much less that the pump direct, then you are losing air somewhere. I suggest a check for leaks with soapy water on several places, while the pump is running:
  • Pump to Valve block pipe
  • Around the diaphragm solenoid (last one nearest the windscreen)
  • Both of the 8mm dryer pipes at valve block and on the dryer.
  • The tank pipe port on valve block with pipe connected.

Not sure how but my previous note somehow got slotted in out of sequence so you may not have seen it

I suspect you have sealed the tank pipe while removing & refitting, hence now pressure builds. !!

As a side note, my project car is rising on the left while parked with battery disconnected !! But I know it's the valves inside the block that need refurb !! At least I'm not losing air.

PETE,

PLEASE EXCUSE THE SHOUTIN' AND THE BAD LANGUAGE BUT THE BL**DY THING IS NOW RIDING HIGH AND SO AM I !

MY SINCERE THANKS TO YOU AND TO EVERYONE ELSE WHO PUT IN SO MUCH TIME AND THOUGHT TO MY PROBLEM.

TONY
Get Fu king in there! Renault may not have been able to help afterall but you sorted it yourself. The answer is always on the car. :D:cool:
 
Pete.
Thanks again.
I see that you a Gas-Man.

Good morning Pete.

I suspect that you are right about my removing the tank feed to check the output and then re-inserting that may have done the trick, even though there had been no discernible leaks with the soapy-squirter apparatus. It was the double-click that may confirm this. It seemed firmly bedded into the valve block but I gave just a bit more shove and got another click. This prompted me to try all the other connections but I did not get any other second-clicks. I have left it on high overnight and this morning it had not dropped a whisker, so touch wood, this particular saga is over.

This will perhaps answer other members who have asked me to say exactly what the ultimate was. Yes, this was the last thing I did before the Eureka moment, but I don't think I would have got to that point without all the valuable input along the way. So I would like to express my profound gratitude for every item of input from so many and indeed all those who subscribe to and support this forum, the very existence of which, came to my rescue.

I live in a very rural area, the downside of which is that I am a long way from anything commercial, but the upside is that I have long forgotten what congestion looks like and I attach a photo of the nearest thing we normally get to a traffic jam. We did have a traffic jam in the village last year but as I knew both of the drivers it wasn't a great problem.

Thanks again to all .

Tony

Why is it a lot of P38 owners have a little sports car handy.

Backup. And motorways.

Done 250 miles in the Jag today. Someone dawdling? Tickle right-pedal with foot and then check the old-boy in the mirror as he disappears. Effortless. Much as I love plugging along in the P38 there is little chance of overtaking anything on the oil burner.

I have just been in to see Monsieur Renault and told him all about the saga to which so many on here have contributed. I wasn't rubbing his nose in it as he had freely admitted that P38s are a bit beyond him. In normal times he does get a fair number of UK tourists limping in with problems with their "foreign" cars and I have now offered him the facility of my EASUnlock (and its operator) for when the next P38 comes in. I was thinking of dropping into the International Rescue section here with my admittedly limited knowledge but which can be backed up by M. Renault's facilities. He is often pleased to pass some of these "far from home lost souls" to someone who speaks their language. I'd appreciate any observations from you or other members who have been able to help out such "lost souls".

I hope your green-laning went well and that IT didn't play up while you were far from home.
