Test for proper clearance:

grab some kid's modelling clay and put a lump in the oil pan where the pickup goes on the raider motor/raider pickup and with a gasket on there, push the pan into place. Measure the clay pressed thickness.

install the starion pump/pickup and put new clay in the pan and reinstall the pan and measure thickness of the clay.

difference in measurements is the length of the add section...

IIRC, it's just under an inch, like 7/8" or so, but MEASURE IT...
