Always wanted to do this, but could not justify the cost of the rotrex units or find anything smaller then the Eaton M45 that was still affordable.

Now the fuel rail is something I got stuck on at first and was a bit unsure of what to do. The T-Jet fuel rail has a return line and built in regulator as standard but the MPI Sei has a returnless system as standard. The only way to use this fuel rail would be to run a return line back to the tank

You can just cap the return pipe on the rail. This renders the regulator ineffective as all it does is bleed excess pressure back to the return pipe anyway. This is what I did on mine so that I could use an external regulator with the standard P75 rail.



I did end up swapping to a different, returnless rail in the end so that capping wasn't needed anymore;
