Thread: FPR Gaskets for 10P engines??

Seems to be a common issue. The previous owner had installed the FPR onto my vehicle with the incorrect gasket too.

Just did mine about a month ago.

Used gasket MSX000010 on fuel block LR016319.

MSO100010 for engines up to 10P15967B
MSO000080 for engines after 10P15968B

These have both been replaced by part number LR016319 which should be the newer casting design shown on UP's "how to". The "tree" of replacement parts for MSO100010 appears to indicate the correct gasket for the new regulator is MSX000010.

I thought there were two types of FPR.
There is the early model type with the two hose connections and the late model type with three hose connections.
The late type has a third hose that runs underneath the inlet manifold.
It was my understanding that the gaskets differed depending on which type of FPR you have.

EDIT: I note that Brit-Car refer to these as single connector and twin to distinguish them:
Early type - FUEL BLOCK CONNECTOR SINGLE TD5 ENG > Products Available > Home > Britcar (UK) Ltd
Later - FUEL BLOCK CONNECTOR TWIN TD5 ENGINE > Products Available > Home > Britcar (UK) Ltd

I am specifically talking about 10P engines as per the thread title which is why I've not mentioned the EU3 FPR or gasket.

At 10P15968B the regulator design was changed, so there you have two different "single connector" fuel connector blocks each of which uses a different gasket. The "two connector" fuel connector block is basically the same casting as the later "single connector" block, with the difference being the extra drilling for the additional hose.

FWIW the same gasket was used on all Td5 engines from 10P15968B onwards - MSX000010.

I did realise that you were specifically talking about 10P engines, but the point I was trying to make is that there is two types of FPR (for all TD5's in general) and two types of gaskets (for all TD5s in general), seems logical that potentially one type of gasket would be for each of the types of FPR...

The problem is the logic isn't always clear or obvious from Microcat, and in this case the answer isn't in the gasket part information - it's buried in the OSI information for the EU2 FRP.

The OSI tree for the early EU2 FPR is



This basically says the original FPR for EU2 Td5's upto 10P15967B was MSO100010, which was replaced by MSO000080, which then replaced by LR016319. The "hidden detail" is the line from MSO000080 to MSX000010. This indicates the MSX000010 is the correct gasket for parts MSO000080 onwards.

Unfortunately I hadn't looked at the OSI information for the FPR until after I'd written the original post.

Anyway I have the MSX000010 gaskets - British Car Components had a couple in stock so I picked one up on the way home from work - and will have a chance to fit tomorrow at some stage.

Job done, although I must have slightly burred the bottom bolt head putting it back on last time which made removing a bit of a challenge!

This is the offending regulator, not sure which pn# exactly but it is not the original part. The original regs are more sculpted in the casting.


Remove the hose to the regulator by pushing in the sprung side panels on the connector and pull back on the hose. It should just slide off.



The connector on the fuel reg is a little harder to get at. I used a flat screw driver to push the black plastic retainer back until it released and then gave the hose a gentle tug.



This shows the design of the galleries in the current EU2 regulators.



The correct gasket MSX000010 lines up with the galleries.


Whereas the crush areas of the MSX100080 are clearly wrong for this regulator.


Most of the job can be done with 1/4" ratchet, 10mm socket plus 125mm and 50mm extensions. A torque wrench is required to do the final tightening to spec. The sidchrome 1/4" extensions have about 15° off-axis movement which really helps. It's not quite as much movement as a wobble extension but is just enough to get onto the bolts with a bit of careful positioning.

Whilst covered extensively by Paul, thought I'd throw in a 'bottom line' type post re the subject of FPR block and gasket selection.

In a nutshell gasket selection is engine serial number driven, whereas choice of FPR block is VIN driven.

The stuff here below I put together a long time ago, not even sure I had posted it to AULRO... here it goes then:
