[Roadsters] fuel pump removal, hmmm

I postd this on 311s, but I'll post it here for those that don't go there:

Since my car is currently in a position to play with this, I gave it a try 
to determine if there was a simple procedure to installing/removing the fuel 
pump. After all, they must have envisioned having to do this as part of 
regular maintenance at some point.

What I found is this: First remove the nuts holding the fuel pump to the 
block. (Question for others out there, are there supposed to be lock washers 
on this? Mine did not have any, seems the studs are way too short, and any 
longer would REALLY make removal a royal pain.)

Next, pull on the fuel pump till the stud flanges just clear the studs on 
the block, then you rotate the complete pump assembly just a bit. Either to 
where a line perpendicular to the top of the pump points to the 1:30 or the 
10:30 position (if you could view it directly from the side of the engine 
block). The axis of rotation goes directly though the center of the bottom 
half of the fuel pump, side to side of the car/block.

Then rotate the bottom half of the pump away from the block with the axis of 
rotation being perpendicular to the position you chose. That is if you 
rotated to the 1:30 position, you would rotate the bottom part of the pump's 
body with the axis going between the 10:30 and 4:30 points. (Conversely, top 
@ 10:30 axis is at 1:30/7:30.) The axis now goes through the UPPER half of 
the pump.

I'm trying to describe something that will be very easy and almost intuitive 
... once you rotate the fuel pump.

I've done this both ways, and have NOT had to lift or move the motor at all.

Re-installation is just as simple (  "Reversal of Removal"  ), except that 
you first must make sure the lever that operates the pump will insert into 
the block and be above the portion of the crank that actuates it.
