For a couple of days I've been smelling a diesel leak.
Sure-enough ... One of the connections to the HP pump was leaking.
[ Bosch pump ... Bosch part nr: 0445 0101 45 ]
See yellow arrow.
I thought it was the clip - Replaced it with new jubilee clip - Still leaking.
I then thought it was a split in the end of the flexible pipe - Cut back 12mm - Refitted - Still leaking.
On closer examination, the leak appears not to be coming from the connection, but from the base of the hexagonal nut at the end of the yellow arrow.
I am going to try to unscrew this nut with the connection on.
Looking at some adverts for recon pumps (£350 !! ... ) you can see some yellow sealant at this point.
I am guessing that this seals the threads and is resistant to attack from diesel fuel.
Does anyone have similar experience ?
I am assuming the connector can be unscrewed and refitted with sealant.
Can anyone recommend the best sealant to use.
Thanks in advance.
