Diesel spill pipes

Just been out and changed over the 3 diesel spill pipes on 97 300tdi to see if it cures starting problem - difficult if left for more than 6 hours or so then starts 1st time every time - fingers crossed n all that! Question is regarding blanking cap / end stop whatever you wanna call it. There wasn't one fitted and I dont know where I'd put it if I needed to. The last injector (nearest bulkhead) looks sealed anyway at the end. Reason for asking is I've dropped the blasted thing I got in new kit and cant find it anywhere. Do I need it?

run the engine, then you'll see why it's needed

Engine running fine - no leaks now or before - as I say end one looks sealed to me and must be or diesel would pee out! I'll post a pic in 5 mins

so which bit have you dropped ?

Dropped the wee end cap thingy but dunno if I need it or not - I dont know what purpose it would serves as there wasnt one there before? Unless I'm missing something.

i think it will be the rubber blanking cap that you get with some kits.

if you find out you do need one,but cannot find/get one.just use a bit of new pipe and fold it over then use a cable tie to keep it folded.

Hopefully - pic shows what I'm talking about. This is the last injector connections - different from other 3 as LHS is not open. So - no blanking cap required? Just want to be doubly sure I'm not missing something obvious here.

that's a old one so no blank cap required - fuel would have been weeing out else

As I thought - not required - just wanted to be sure there wasn't something hidden away anywhere. Fingers crossed we'll have a first time start tomorrow! Thanks all

you not in work sean

Why should leaky spill pipes affect engine starting? I've never come across that in 40yrs messing about with diesel engines.

Perished pipes allow air to seep into system overnight - making 1st start after a period of time has passed (in my case about 6 hours or so) very difficult. Hopefully new pipes will be airtight. I dont even think you would necessarily see fuel leaking out - more a case of air leaking in. Make sense?

If renewin' spill pipes always replace the copper washers anaw

Naw - cos these were just the rubber type. I think youre talking about the rail type.

D'ye mean like these?.....

Yeah - that's what I'd call the rail type mine were just rubber hoses.

Yes, makes sense. Never had it happen on any of my diesels. Maybe I'm just a lucky b----r.
