9.5mm seems small : when I measure the hoses I removed, they’re more like 11mm : would they have stretched this much ?

I can’t check the fuel rails have I’ve sent sent away to get cleaned and painted
(my engine is the same, 6.0 from 1993)

I suspect the number Mr. Faircloth gave you is CORRECT. He did service my injectors and replaced the two hoses on my rail a couple of years ago. Yes, factory 6.0L V12

thanks Steve for confirming : that’ll save a lot of guessing
the hoses were VERY tight on the rail, so must have stretched

I got some 9.5mm fuel hose, and they need some persuasion to get on the fuel rail nipples
I didn’t want to use any kind of lubricant, by fear it could damage the hoses or help them get out later



no picture of the 4th one, but it’s about the same of the others

They’ve been changed before, and the end cups were lost / removed , and are unavailable for a while

I wonder if adding the same worm clip as before would be useful or not, most I’ve read was saying they could do more bad than good

as I send the fuel rails out to be powder coated, I can’t remember is the sensor fitting in the right rail is blocked or not ?
the rail came back like this

Is a bit late now…since the hoses are already fit in place…you can use an FI hose clamp…solid body…not a worm clamp type. The sensor bung is welded to the outside wall of the fuel rail…there is no contact with fuel. SD Faircloth www.jaguarfuelinjectorservice.com

thanks for the pointer, I was looking for “cups” like those fitted by Jaguar, but they are unavailable
you mean such clamps :

That clamp looks fine. SD
