Default HPOP a warning (Fuel pump bolts)

The HPOP that triangular looking casting hanging off the front of the driver's side cylinder head!
HPOP in fact a term used in the trade for the high pressure pump feeding the fuel system .

Its held onto the head by three (3) 7x1mm bolts that are sticky!
So to be used only once! Unless you daub them in blue loctite as a "get me by!!
Failure to check on this pump's security can, and in some situations will cause detachment and camshaft drive gear damage which drives the HPOP pump itself.
Seen two this week!!

This is a royal wallet flush repair so check yours every so often.
