Fuel pressure testing on C4-100 (v6-2.8L) & C3-5000 (I5-turbo)

[William Magliocco]

I'm sure someone out there has already walked down this road, so allow me to ask 
for directions:

Right now (immediately, if not sooner) I need to come up with the appropriate 
bits to measure the fuel pressure on my '93 Audi 100.  This being Audi/Bosch and 
all that, the fuel pressure test kits you see at the chain stores won't do the 
job (at least as packaged)...The car is hard starting when cold, it looks like 
low pressure.  Those who know this car know it lacks a test port on the fuel 
rail.  I am hoping it is NOT the fuel pump as I replaced that two years ago.

Later on, I would like to use the same gauge (if possible) to measure the fuel 
pressure(s) in a 1987 5CSTQ I have stored away.  It used to start & run no 
problem, but I think the fuel pump in it died a couple of years ago.

So, if any of you out there have recommendations on what to buy and what 
adapters/fittings etc. I would need, please advise.

Thanks
