At least it should be very clean when being put in the car!
** TIP **
On the other side of this block are two hoses that are nicknamed say hello to
The Hose from hell
The Hose from hell On Earth
I strongly suggest whilst the engine is apart you change them so you never have to once everything is back together. These hose's make MR2 owners cry when they leak, I'm sure its not as bad on a kitcar..but why take the risk of having the hassle.
The smaller one comes with clips and is about £15 the other about £30....money well spent!
