Ive had a disaster fitting a new fuel lift pump to a 300tdi.
I fitted the new pump to the block, fitted the hoses using new nuts and olives (no martini though). Started the engine and everything seemed fine.
Took it on a test drive, still lovely.........
Got back, did a final check for leaks and found a slight weeping leak on the union connecting the lift pump to fuel filter .
Gave the union a slight tweek to tighten and the next thing I know is the metal stem from the pump is spurting diesel all over the engine bay.
In tightening it, I have created a small split in the exit pipe where it joins the pump body.
Is there a correct way of tightening fuel hose unions (compression type) as I dont think that I overtightened it and I did counterhold the flexihose end with a spanner as I tightened the nut.
I will be very nervous when I fit the next pump......... Any advice on best practice would be much appreciated.
