It was over spec... I had them cross reference the Airtex E3270, they had a similar pump for $70 vs the less than $40 on Amazon for the Airtex. I was already working on the truck that day so I went ahead and purchased the one from O'reilly.

For what it's worth, a 200hp naturally aspirated motor needs around 16 gallons per hour of fuel flow. The Rover V8 operates at a pretty low pressure, if I recall its like 37psi, which makes the requirements very low.

The O'reilly part number is E16008 and will support around 300hp.

You'll also want a new strainer: S13003

 

It's a return fuel loop, anything that doesn't get pumped through the injectors will just end up taking a long trip back to the tank.... albeit at a quicker rate than the line is used too...... They should've used a 300hp engine to weigh anchor in the Rover Love Boat.
