Fuel Filter Changing question

'89 RS, TBI, Fuel Filter on rear cross member.
When I loosened the connections, gas of course
ran out. But ... it kept running out. After about
a gallon I tightened connections and am asking
you guys. Seems like it is syphoning out of gas
tank. Suggestions please?

Re: Fuel Filter Changing question

On the TPI's, it suggests relieving the fuel pressure in the fuel system by pulling the fuel pump fuse and letting the car run until it dies from lack of fuel, and then trying to crank the system over just to make sure it's good and out of fuel. Give that a try and see if it helps ya any.

Good Luck!

Re: Fuel Filter Changing question

I thought it was the F/P,Fan,CH fuse, but apparently not.
2 fuses marked F/P - inj 1, and F/P - inj 2.

Re: Fuel Filter Changing question

that shoudlnt matter, i when i did mine i sat there and waited for it to stop then realized hey....its gonna keep going, someone brought up the pressure thing so they popped my gas cap and it hissed like usual, the flow slowed down but kept going. My advice is do it fast and do it right, to speed things up once you pull the filter drain the gas into a clean bucket or something and spray the nuts with like wd40 to get the dirt off, put the new one up and have at it

a gasoline bath does the body good.......atleast ive been told so lol

Re: Fuel Filter Changing question

It's, supposedly, a fuse located behind the passenger side headlights near the battery in a black fuse box. I "believe" there is an orange wire leading to it. Once you get the filter changed, remember to put the fuse back in and prime the system. (IE: Turn the car on for a bit but don't turn it over.) I'm looking to change my fuel filter out today myself, we'll see how that goes. As far as a gasoline bath is concerned, I wouldn't suggest it. Gasoline can irritate the skin and also the eyes very badly.

Re: Fuel Filter Changing question

yeah the gas never stops coming out. found that out the hard way too. and yes there is a fuse located behind the passenger light on the inside of the fender. remove that one then crank the car untill it wont run. if you remove the injector fuses it wont relieve the pressure.

Re: Fuel Filter Changing question

i had the same issue but i found that when i disconnected the fuel lines in the engine bay, not at the throttle body but where the flexible lines enter the hard lines, that the fuel stopped pouring out from the fuel filter. i know it doesnt really make sense but it worked for me after about 45 minutes of letting the fuel drain out, and no the gas tank did not run empty, there was still a lot of gas left in the tank.

Re: Fuel Filter Changing question

I just changed the fuel filter on my car.

1986 IROC-Z 305 TPI

I started by popping the hood. I then started the car. I found a fuse behind the passenger side headlight near the battery. It had an orange wire going into it. I pulled the fuse and the car immediately died. I set the fuse a side and got back in the car and tried to crank it for a while. I then jacked up the driver's side rear tire and located the fuel filter. It was located forward of the rear tire, sorta near the center of the car in kind of a recess pocket. I sprayed both sides of the fuel filter's fittings with Liquid Wrench. Then I took a lunch break. About thirty minutes later I returned to the car. I put down a crap load of old t-shirts on the ground to soak up any fuel. I used a channel lock and a 5/8" Box wrench. I started by loosening the fitting on the output side of the filter. The side where the fuel exists the filter on it's way to the engine. I did this by using the channel locks to hold the fuel filter's fitting and the box wrench on the fuel line fitting. I applied very slow pressure to the fuel line fitting until I could feel it starting to move. At this point I stopped and checked to make sure it was the fitting moving and not the fuel line twisting. Once I was sure it was the fitting, I continued loosening the bolt until I could untwist it with my finger. I did this slowly anticipating fuel squirting everywhere seeing as I wasn't 100% confident I pulled the right fuse in the first place. When I got towards the last few threads there was a spirt of fuel for a moment, and then fuel began to pour out. A bit at first then it slowed and finally came to a slow dribble. At this point I loosened the input side of the filter's fitting in the same manner. The filter is held to the bottom of the car via a bracket, or at least mine was an I just twisted it back and forth out of the bracket. Be careful not to tip the fuel filter as it still contains fuel. I installed the new filter in reverse order, taking care to ensure the filter was installed with the proper fuel flow. I must note that the fuel never fully stopped dribbling out of the fuel lines, but wasn't so much that it caused a mess that the tshirts couldn't handle. Also, while installing the new filter, I found it easier to tighten the input side fitting first. After the filter was installed and the fittings tightened down, I reinstalled the fuse and turned the car on to pressurise the system. No leaks. I then lowered the car and started it. It took a second, but it started. I checked again, no leaks. Took the car around the block and everything seems okay.

I wore sunglasses to prevent any eye irritation and went thru about twenty old t-shirts. All in all, took about an hour including the 30 minutes I took to let the liquid wrench soak in.
