Fuel filter replacement LT4
I recently flushed and replaced my coolant and while I had the car up I figured I'd replace the fuel filter. I could not get to the upper fittings from below. I think if it was on a lift I could get to them, but 12" off the ground I couldn't do it. I was thinking of disconnecting the fuel lines from the engine and side frame and seeing if this would give enough slack to get to the filter better. Has anyone done this ? Do you really need the tool to disconnect the fittings at the engine ? Thanks :confused: :chevy

I just ran into the same problem on mine. What especially worries me is how breakable everything in that area feels. I think that using 2 open-end wrenches to loosen it up might do the trick without disconnecting anything else. Keep me posted - once I get back from school again I'm going to give it a shot. I could use suggestions.

If you use the proper tools you should not have a problem. Use two line wrenches. Line wrenches are like open end/box wrench with a slit on the box end.

You're right, it's simple with a lift. It took my mechanic about 5 minutes (while I was talking to him) to change mine. The first time I did it, I pulled the fuel line out from the top. Since I had the car in for new plugs, I figured I'd have him do it again.

It is tough to get to them with the cats installed, but it can be done with a lot of dilligence. You could remove the line from the fuel rail but I would keep trying it without. Took me about an hour and a half to swap the filter the first time I did it which should take 15 minutes if it were not for the location.

I know this is basic 101 maintenance BUT!!!!!!!!!!!
PLEASE MAKE SURE THE MOTOR IS COLD.
DO NOT EVER CHANGE A FUEL FILTER ON A HOT/WARM ENGINE.
I know everyone knows this but there might be just one, someone out there that doesn't.

Re: Fuel filter replacement LT4 (crewzenLT4)
I use a flare nut wrench on the top fitting only to hold the line... There's no room up there to get two wrenches in...
Then I turn the filter off the line rather than the other way around... It's easy that way... If I don't take my time, I think it only takes about 25 minutes now to change the filter...
The filter itself has nut type ends on it, so you shouldn't have a problem getting a socket on the bottom end of the filter itself...
Like everyone else mentioned, make sure the exhaust is cold... The cats can stay pretty hot for quite a while after the engine is shut off... Any heat around fuel vapors is bad...
