For Land Rover Discovery 2 Defender TD5 2.5 Fuel Pressure Regulator Repair Fix 747180984637 | eBay
Quality product, Bosch regulator, comes with all o-rings (including the thick one between FPR and engine block) and has gaskets for both types of FPRs so you can't go wrong. X8R also have a good youtube clip showing how to R&R the FPR and do the "rebuild".
I used a long ring spanner to knock the two top bolts loose. I accessed the bottom bolt underneath the front mudguard with three long extensions and a 10mm socket.
Getting the FPR back on was a bit more challenging than getting it off. Putting the bolts through the gasket and then a rubber band around the bolts certainly helps (once all bolts are started you can cut and remove rubber band). The two top bolts were a bit tricky to get started with the manifold in place - you need to get exactly the right angle. Once the top bolts were started, the bottom bolt (which is supposed to be the difficult one) was easy with the socket and extensions.
I made 2 locating pins by cutting the heads off 2 bolts that i bought just for this job. Screw the pins in far enough to be secure or till they stop - slide the gasket on the pins (leaving a couple of threads exposed on the pins will stop it sliding off the pins) - follow with the FPR body (with hoses removed) - hold in place and with free hand remove one pin and replace with an original bolt - repeat for the remaining pin. I put a”how too” post up with photos 4 maybe 5 years ago. I hope that it has helped someone.
