[DML] Re: how do i depressure the fuel system?



Whoa WHAT are you talking about? There most certainly IS pressure in 
your fuel system even with your battery disconnected and engine off. 
Just because your car is off, DOES NOT mean there is no pressure. 
It's called REST PRESSURE! It's what your accumulator is installed 
for. If you park your car for days and want to see if there is 
pressure-just depress the air sensor plate. If there is a slight 
force pushing against you there is still pressure in the system (try 
it just after you shut off your car to see what I'm talking about). 
If there is no force and it moves freely up and down-still assume 
there is a very SLIGHT pressure to be safe-but not much (will never 
be like this right after you shut off your car-unless you have bad 
accumulator or ck valve). Even with no pressure you'll still have 
fuel spilling out of the lines. What I do is put a nice big rag and 
wrap it around the cold start valve-once you have a wrench on the 
connector on top of the csv put the rag around that as well-and 
slowly open the connection while you're WEARING SAFETY GOGGLES even 
if the connection is covered. This will depressurize the system, as 
well you'll be able to collect most fuel without making a mess (once 
you loosen the connector take off the line and let the line empty 
into a container (a cap off of a spray paint can works great-just 
stick it between the cold start valve on the hose going to the idle 
motor or put it on between the air sensor and 'W' pipe over throttle 
body-and put the end of the line into it). It's very easy to be 
overcome by fumes working on fuel systems-so do it with a fan 
running and in a well ventilated area. -----Dani B. #5003
