I have done it with an Electric Pump on Mercedes and other Inline Fuel Injection Pumps and it is easier then using the Hand Primer.
Also one place I worked they had a gravity feed type set-up. But, when you do that you have to hook it up directly to the Fuel Injection Pump Housing; with the small one we had there would not have been enough pressure to push past the Valves in the Fuel Supply/Lift Pump.
If you have an MW IP you are supposed to replace the Copper Crush Washer. If you have an M IP you are supposed to replace the O-ring and the Copper Crush Washer.
The last time I did mine I had not ordered any new Crush Washers. Since I have other vehicles to drive I fgured I would re-use the Old Crush Washer and if it leaked I would just let the Car sit till I got a new one.
So I lucked out and it did not leakd. However, If you do not replace the Copper Crush washer you cannot count on it not leaking.
