OK well i did the filter on my 85 c4, 45k miles.

It was easy.
Located pass side near jacking point. let car sit for a day, then pushed it into the drive way.

1. Losened both sides of the fuel filter Completely
2. Loosen the fuel filter mount
3. Losened the fuel line support on fire wall side.
4. Spread the fuel lines, Gas will now leak down to a bucket and filter will fall in also. (very little gas leaked out)
5. Put it back in, make sure the flow is correct.

This took me 20 min start to finish taking my time.

Now for the good part.

85 c4, 45k miles, original filter.

Here is the pics, you can see all the junk inside of the filter and then when I banged it out all the junk that fell out.

I would say its a combo of dirt and filter deterioration.

I cant believe you have an '85 with 45K miles and just now changing the filter

...i think you forgot a step..1st, you pull the fuel pump fuse and start the car to remove the gas and the pressure from the lines. then, contiinue!

Wow, that's nasty! Looks like underneath my bed.

I think thats why he

" let car sit for a day, then pushed it into the drive way. "

...could be although most people who get the idea of changing the filter would do it almost immediatly and not let the car sit for a day...just my $0.02....

Here you go!

I didnt pull the fuse. It sat and that was it.

Also I owned that car since Oct, Not for the entire 45k

Dan,

Did you use ramps or jack stands?. I had mine on a lift and it looked tight and a real pita regardless. Fortunately, the filter case looked rather new so I'm saving that job for the spring.

Does it idle any better since you changed the filter? Better acceleration? Also, how did you cut open the filter. Im curious to see in my old one but since it is covered in gas and if you use a saw...and a spark hit...bye bye....Has your filter been in there the whole 45,000 miles? Thanks. Just wondering what you thought the effects of just changing the filter was.

corvettedan22

I just jacked up the pass side enought to get in there. Piece of cake.

Im not sure if it runs any better, I mean the car ran and idled fine before.

At least I know it must be running better..



I cut it open with a saw.
I wasnt concerned about a spark, because its not like its going explode. Worse case it would catch on fire.. Not to mention its aluminum so I think thats less sparking....

He had the right idea pushing the car out. Otherwise the cat converter which is right near it gets too hot.

Man, now I really need to change mine. The problem I have, which I do not know if its just me, is that the cats are right next to the filter. It's almost impossible to get a wrench in to remove any bolts. Any suggestions? Other than drop the exhaust.

I did my 92. the back connection was accesable, but with the help of the Forum i was able to get to the front connection. Pop the hood and loosen the bolts from the fuel line bolts from the firewall and pull the fuel lines and filter out.

good luck.

85 is easy nothing in the way,,,,.....

I used to goto my parents house to do all my work, so my car was always hot when I arrived. I just put the garden hose on a light mist and got the exhaust damp. it cooled within a few minutes, enough so it wasn't combustion hot anymore. I figure if rain gets on it and it doesnt crack from heat, water from a hose isn't going to hurt it either. That makes your "I want to change it right now" project happen that much quicker

MY93TOY

I bet you feel much better now that you replaced it!!!
I sure did after I replaced mine last week.

derekguzz

94 with 146,000 and i doubt its ever been changed !!!! LOL why im laughing i dont know cause i dont care...
