As part of the gen2 1441 project it was time to look into the fuelpump. According to the manual the stock pump is capable of 79LPH which corresponds to 220-240hp. When opening the pump the Mitsubishi type code was exactly the same as gen1, only the powerconnector was changed so no doubt - this pump needed to be replaced.
Then I laid on the desk three pumps next to each other:
Stock gen2 pump
Bosch HP pump
Walbro HP pump
The Walbro is a bit thicker and also longer which meant that it was not a direct fit. Like with gen1 the Bosch pump is a direct fit, only powerconnector needs to be modified and top plastic support cut from one edge.
Bosch 0 580 314 068 engraved in plastic casing that needs to be cut open to get the pump out, below is a picture of the plastics cut open. Bosch us supposed to be an Audi replacement pump. Same pump may be inside some other casings too, but this is the one found so far. We flowtested all three pumps last summer. Bosch flow is the same with Walbro, but Bosch is capable for higher pressure before safety valve opens so Bosch is obviously the favourite choise.
