Walbro 450 / 39mm in tank fuel pump kit urs4/urs6
Kit includes your choice of a Walbro 450 or 525 fuel pump (we recommend the 450 for cars up to 600hp, select the 525 for over that), inlet sock filter, electrical connnector, and adapter hose. Note that we currently ship our dual pump bracket with this kit so we don't have to stock both types of brackets.
We've also found a nice 3d printed replica of the factory removal tool that works well in helping to remove the pump. you can download it from here
