Anyone know of a vehicle which uses, or a supplier of an inline heater valve?

Cheers.
Pete.

They also do a 15mm one.

I think mine came from an old fiesta....I paid £2 for it along with a fistfull of fuses from the local scrap man

Mine came from a Focus I think - electric too

If you fancy one like that shown in orwelly's post, I have one brand new, £10 posted. Cheers Ray
