vacuum hose for 3.9 v8 efi

Hello

Does anyone know the internal diameter of the vac hose I need to buy for my 3.9 v8. I would check on the car but its currently in Spain.

Many thanks Chris

I know of 3 different vacuum hoses that the 3,9 has, but haven’t a clue of their inside diameter. So letting the Forum know the application the hose is for could help.
If I correctly remember, the cruise control vac hose which I replaced was 7mm ID.

Hello

Im thinking of vac pipe to fuel pressure valve and also from the inlet manifold to dizzy

Thanks chris

The fuel pressure valve pipe is only around 16cm long and is moulded to for a bend in the centre so no kinks, and its obsolete of course like the dizzy pipe, this pipe is thin around 5 or 6mm, at the end there’s a rubber elbow plus a straight connector to enabling the pipe to attach to two nipples that require a larger diameter.
The part numbers as far as I can make out were ETC7313 & ERR4676

Unfortunately no picks allowed at the moment.

I used the same size hose for both of those parts, i bought a couple of different size samco hoses from memory i think 3 or 4mm ID,
