I have both of those parts, but the pressure sensors very seldom go 
bad. OTOH, the 007 number you have is for '70-1 and is a completely 
different beast. You want numbers that are consistent for a given 
year of FI. If your '73 actually has been switched to a '71 FI 
system, then the numbers below will be wrong.

The '70-1 TVS has 4 terminals. The one for '72-3 has 5.

The '73 numbers are:

Pressure sensor: 311 906 021 E / 0 280 100 116

Throttle valve switch: 311 906 111E / 0 280 120 024

I have good used pressure sensors and both NOS and good used throttle 
valve switches. There were actually several different versions of the 
'72-3 TVS, so there are a couple different Bosch numbers.

I'll send you my instructions for adjusting the TVS, since the 
Bentley gets this wrong. The different TVS part numbers are called 
out in there.
