its an 86 with the 2.8v6. i was wondering how to relieve the fuel pressure in the lines so i can change the fuel filter...

im asking this for a friend...thanks alot

 

Pull fuel pump fuse, start engine, let it run until it stalls.

 

You can also just let it sit overnight and the pressure will be down enough in the system that you can wrap a shop rag around the fuel filter fittings and use a catch basin under it. Not much gas comes out.

 

fuel pressure guage to the schrader valve, and hit the reset button a couple of times.

 

"Pull fuel pump fuse, start engine, let it run until it stalls." that somewhat worked for me but I still got shot in the face with tons of gas. Be careful.

 

Oh it's not that bad... just unscrew it after its been sitting for a little while. Then again the way gas prices are... like an ounce of gas is like 600 dollars... so I can see why it'd be a problem wasting gas

 

Best so far. You can just turn the schrader cap upside down, and hit the stem with it and a rag. Rag soaks up the gas and keeps it outta your face.


Screw the hard stuff with trying to find the fuse and start the car n crap. Geesh, you all do stuff the hard way

 

What's so hard about pulling the fuel pump fuse and turning the key?

 

I just find it easier to hit the scrader valve then to crawl under my dash, fight to get the fuse box down, then pull the fuse.

To each there own Aslong as you dont get an eye full of gas.

 

I do what Dale does, only on Redraif's the cap is flat on top so I have to use a screwdriver to depress the needle in the schrader valve. Either way will work.

 

heh, when i replaced my fuel filter last, i decided i would just loosen the fittings at the filter enough to drain the gas out into an oil pan. . . but when i came back a while later it was still pushin out gas like a champ . . . i guess i had started a siphon because the opening was below the tank(woops!), so i ended up changing the fuel filter with gasoline dripping down my arms and all over me(i already had one end of the filter off, so it was get soaked and still have to change the filter, or change the filter and get more soaked. i only lost like 1.5 gallons of gas, but man i stung like a mother****er for twenty minutes after.

 

Take the gas cap off first. Yes, you created a siphon, done this a few times myself.

 

Hense why it's recommended to pull the fuse and run the engine. Usually there will be enough fuel pulled through the fuel lines, that a siphon will not be created.

 

Raven, IIRC the gm manual says to hit the schrader valve on the fuel rail.

However, on the s10 TBI system, the only way was to pull the fuse, or reach under the bed and pull the plug to the pump, then start it.

Either way will accomplish the same thing.

 

Every manual I've seen says to pull the fuse and start the engine, S-series or not, in fact I know for a FACT that the J-body manuals all say to pull the fuse, and they do have a schrader valve.
