Beginner Question

The answer to my question is probably simple to everyone in this forum but me.

Where is the fuel filter on my 1986 GMC Sierra?
It has the 5.7 V8.

Thanks for babysitting me.

It is behind the big nut where the fuel line goes into the carb .

Re: Beginner Question

The other thing is you need to be very careful when removing the line going into the nut. You need a flare wrench at the very least.

We'll try to get a picture up asap---if i may so bold to say that on behalf of everyone else

Re: Beginner Question

MOTO, Thanks! Just picked up some flare wrenches and I'm ready to give it a shot.

Little backstory... This truck was the work truck for my dads company when I was a little boy. He has kept it around and has now has passed it to me to do what I want. It is a 1986 Sierra and has 48,000 original miles.

I am 36 and have had 5 different operations over the last couple years due to work related injuries. Piddling with this truck has kept my mind busy and it has been a great source of therapy. Im super proud of it and will need you guys a lot over the next several months.
Thanks For Putting Up With Me'

Re: Beginner Question

After you loosen and remove the fuel line from the filter housing you need to unscrew the housing. Go slow. It's fine threaded and prone to damage. THere's a small filter in there held in place by a spring. Be prepared for the filter and spring to pop out.
When you put it back together the spring goes first, then the filter with the open end pointed back towards the fuel line. There's a small flat washer that goes on the housing to seal it to the carb body. Screw it in gently and snug it up but not overly tight.
Hook the fuel line up.
Do not use any type of thread sealer on the housing threads or on the fuel line.
Here's a good pic.
