my advice is dont do it.
its a hell of alot of work.
if i would have known how hard it was then i would never have done it.
for me the powersteering pump was no issue as i fitted full mk5 escort zetec setup.
the issue was the rack/ steering colum and track rods.
i have a modified nissan bluebird rack, custom hoses, modified track rods, modified brackets, modified bulkhead, modified steering colum, modified clutch pedal and more!!
hell of alot of work.
it works great but it ought to with all the time and money i spent doing it.
answer: sell your escort and buy a fiesta mk3 as they have everything available from fords.
