Not sure this will help as mine is a Mk 7 Jumbo.
You need to look underneath first off to check out any restrictions as in cross members,wiring etc etc.
I fitted mine behind my Drivers seat at the start of the load area,rippled floor is a bit of a pain but I bought an Eberspacher fixing plate so you just drill one big hole around 125mm with a hole saw along with 4 other small holes around 6mm to anchor the plate to the van.
My pump is fitted in a void underneath,I'm guessing where the fuel filling pipe would be should my van been LHD.
Fuel line comes from my tank,drop the tank and fit a Genuine Eberspacher "Fuel Pick up kit" try heaterpartsdirect on EBay
You may have to check with Ford first though that your sender unit on the tank is the same as a Mk7
,
Should you fit that kit,BEWARE NOT TO CUT TO MUCH OFF THE PLASTIC NIPPLE that the straw/pipe fits into as you will not get an airtight joint thus giving you problems getting fuel from the tank to the Eber.
Hope this helps a tadge...
