Default Rover 75 fuel pump 130 bhp

Hi iam new to this group after taking charge of Father in laws 2005 cdti
He is now in care home with dementia but kept on reminsing on his beloved rover so I had it moted failed. Welding on 3 jack points on cills and broken coil springs.
Iam handy with welder as I restore old Sunbeam Alpines.. So all work done
I have been using care for 4 months now and l just love. Love love it.
Now to my query
It let me down a few times. Think it's intermittent fuel pump gremlins... Single pump system.
So now I've removed pump from tank then motor from pump( very good instructions on this forum.. Only extra tip would be soak motor carrier in red hot water it Seperates easily then)
Now to point it seems like all motors are for 115hp engine? Are these same motors as 130 hp engine? If not where can I get correct motor..? Iam a tight NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- so cheap as chips
Cheers

Same pump and same engine, its only the map that's different. Would be worth considering getting the '160' map although other maps are available!

I am not convinced a CDTI needs a remap unless it is towing a heavy weight such as a caravan, I am of course assuming my CDTI has not been remapped.

Very unusual for the single pump to fail, what are the symptoms?

It's certainly a capable engine without a remap but mine was a 116 so the map made a significant difference and for me it wasn't a question of if it needed it but more that it makes it a much more pleasant car to drive with it

The CDT is a dog, I have one. Without doubt the CDT does need a remap but my CDTI and the one I test drove when I got my CDT are noticeably livelier. I would say anyone with a CDTI, should drive around with it for some time, before deciding to remap to 160, however, if they are going to tow a 4/5 birth caravan get it remapped. 2 birth or 3, try is standard and then decide.

Nip over the water and see the mg rover breakers on English St they will have one in stock, must be from the single pump system as the in tank pump from the twin pump system won’t be any good for you.

It won't be the pump, when it doesn't start or cuts out have a look at the oil pressure warning lamp on the dash, and if it is lit

Take a look in the plenum chamber to make sure the ECM isn't wet, characterised by a tide mark on the pollen filter.

I can count the number of single pump variants of 75 where I have had to replace the pump on a single finger, and that was after the chap I bought the car from had fitted a pump from a twin pump car
