Timing via pump fastenings and checking current timing

[ukvolvo]

I am acquiring tomorrow a see saw gauge with various shafts etc from a local diesel specialist. This allows you to time ve pumps without taking much off apparently as it comes out sideways once screwed in and the clock locates on the opposite end. Probably a very pricey item once upon a time.

Before i go into t belt etc etc i suppose i should check the timing at least so i may attempt it this weekend.

I have seen videos timing with the pulley and videos using the pumps position. If mine is out is it ok general consensus wise to use the pump location to time? It looks alot easier to do.

Thanks
