fuel pressure relieved every time engine off.??

i was reading in the Chiltons manual, cause i was gonna replace my fuel filter. And i was reading how to relieve the fuel pressure and it said that it automaticaly releives itself after u turn the engine off, is this true? i never got the fuel filter off cause its on so freakign tight so i dont know for sure. any tips on getting the filter off also?

The fuel pressure on a TPI car should hold for quite some time, so you will need to relieve it at the schraeder valve on the fuel rail and remove the gas cap. If it relieves itself quickly once you shut it off you have problems. Spray the filter connections with some liquid wrench and let it sit for awhile, and use some basic open-ended wrenches to take it off. Hope this helps.

i to6tally agree with the liquid wrench idea,i always spray some kind of lubricant on a filter before cracking it loose....
you dont really NEED to relieve the pressure.
If you decide not to,just make sure your mouth is closed,and eyes clear away(wearing goggles/glasses) from the filter when oyu crack the lines....
one thing i dont agree with is the standard open end wrenches...if you have access to them,use open end box wrenches...
basically they look like 16-point box wrenches with a small chunk taken out of them
using those you run more or less no risk of rounding off the fuel line fittings...
regular open end wrenches have a tendency to round out slightly rusted fititngs....
hope it works out....

To relieve the pressure, disconnect the fuel pump relay and crank it over. Opening a pressurized system is dangerous. One spark and ... bye bye... Not to mention getting sprayed...
