Here is a picture of the revised bottom hose, it now goes over the steering rack. The rack has been moved back flat with the chassis and the fuel pump modified to allow some gap so we don't have any 'questionable' adjustments for the SVA.
I've also removed both sets of headers (exhaust manifolds in UK speak - but it is an American engine) added some copper gasket seal and used some spring washers to ensure a tight fit against the cylinder heads.
Refilled with coolant so we'll see if we have any leaks in the morning. I need to create a new fan mount as the new route of the lower hose gets in the way of the old one.
