HEllo all,

Just did a cfi to mpi conversion for my old man's Ea fairmont. Started first go & seems to be running fine but just wondering weather i should get a fuel pump & dizzy from a mpi motor aswell?

I noticed in the manual the cfi needs 100kpa pressure wheareas the mpi needs 200kpa. Just wondering weather its the fuel pump that actually changes that pressure or the fuel regulator?
