aye mk2. you need to fit pump complete with the plastic housing, just a case of is there enough room. the plastic housing acts as a fuel swirl pot, just need an in-tank pump keeping the plastic reservoir topped up with fuel. the bottom nipple on the back of the plastic housing is the feed from the tank, the 2 nipples on top are return from engine bay and return to tank
oh and the metal cylinder on the left side is the filter, the one on the right is the accumulator. you can take the mk2 filter off and use the bay one if you like, do whatever is easiest. you need a fuel accumulator though, use the mk2 if one isnt fitted now or keep the van one iffitted and its easier
