A blown fuse is hardly going to be intermittent is it?
indeed, as I thought too
however 2 have had this problem cured by replacing the fuse?? so was worth a look??
Not if it's intermittent. Blown fuse is a hard fault. I had that when a couple of plugs were down. Changed them it went away. But can't see how the ECU would know that. More likely a dirty connection from ECU to relay or an earthing problem in relay pull circuit.
You need Bosch 2 464 509 015. Link to source in my "How to". Price has gone up and currently out of stock. They are on the bay thought. Or Diesel Jones will have them.

Diesel Jones don't bother unless you want to spend 30mins arguing about not buying a new pump!!
eBay took 3 days to come from Latvia and was a genuine Bosch part

no you just take the top off 4 bolts, then 2 tiny torx screws that's it
(will be easier if you remove the inlet manifold though)

The engine temperature sensor that is located under the manifold at about no 5 cyl will affect cold starts and idle when cold could be worth replacing and try again
Hardly unless the engine was hot. You want to be looking at it just after start up from cold it should be near ambient then rise. If it's more than that then you have a problem.

it had been ticking over for a short while and temp was between quarter and half on the gauge and it rose to 69.5 after a 30 min run at 50 mph and the gauge was at it normal position at half way
If it shows ambient after cold start then rises all should be ok. The fuel is constantly cycled through the system so depending on how much there is in the tank it will get warmed on a long run. It should never get anything like as hot as the engine though.
