non-permenant 300tdi boost pressure reading point?

Lots of people cut the line between the turbo and the ip, and insert a tee. I guess i could repair the line after with a straight couple, but there must be a simpler, non-destructive, place to get a reading from?

There's that planked port on the rear of the inlet manifold, but im not convinced im going to have enough clearance (on the disco) for a fitting there (need to check)

This must have been done a hundred times before, so im wondering what others do for a non-permanent installation (if i wanted it permanent, id just cut the line, as per all my search results!)

Thanks

I drilled and tapped the manifold for a barb fitting and if I didn't want it permanent I could have used a plug after removing the barb. Think I did it 1/8" bsp , I had the bits so cost me nowt.

I found a note on a forum suggesting that a pug fuel banjo would fit, which is, i think, 12mm x 1.5 pitch.
Ive also gone and checked the disco, and the inlet manifold is forward a bit from the back of the head, so there is clearence there too.

Im going to order an 12x1.5 bolt, a 12mm banjo, etc, and go from there.

Ill post again when it all turns up, as to if its the tool for the job.

Thank you.

There is plenty of room behind the plenum for a banjo - the boss is used on the EDC 300's for a sensor, and, as mentioned above, a banjo fitting is the ideal way of accessing this.

Broken the trailing arm on the disco, so not a lot more happening, however, ive picked up a double banjo bolt which should fit the IP.
Also purchased the bolt for the back of the manifold, but they sent an M10, not an M12, so that's not happening yet.

The plan is to measure at the IP, to check its 'seeing' the pressure, before swapping, possibly more permanently, to the manifold.

I bought one of these for my TD5, I have seem they do also make them for the 300tdi, they just arnt listed.

Comes with lil rubber thingys so you can cap off the nipple. Also means you can remove your current EGR and sell it on mitigating the cost.

Best bit is it sits just infront of the inlet manifold, giving a very true reading. My Nanocom reads, 17.4 psi at full boost, while my gauge reads just under 19psi. 1.6 psi difference can be put down to the cheap boost gauge.

On my EDC that sensor (MAP) comes from wastegate actuator not from manifold.

I just tee'd this pipe and put a straight connector in after... couple of push fits no big deal
