My 2001 Z06 just turn 50,000 miles and it was time to swap out the fuel filter.

You'll need these, Go buy 6pc A/C & Fuel line disconnect tool set at any auto part store. kit# T70098 Also have a bowl or something to put the 1/2 cup of gas that comes out when you pull the line out. I got the fuel filter from my brother who owns a shop and cost me $32.00.

Location of the Fuel filter is on the driver side in front of the rear wheel.

Jack up the car.
1: Remove bolt, forgot what size.
2: I use a small flat head screw driver and push the taps in.Pull the line out. alittle gas will come out,
3:This is the hardess part,you be using the 3/8 quick disconnect to release the fuel line. Insert it in and push and you will feel a soft snap. You are going to be pulling the fuel filter very hard and holding on the fuel line.(gas will spill out)

4:Now you got the fuel filter remove. Remove the plastic taps on the old filter and put them on the new Filter,Put everything back.

Now don't start you car right away, Turn you key a few times to fill up the fuel fitler before you turn your car on.

p.s I was doing this on my back, if you have a lift, it would be so much easier...good luck.

oh...on another note, My fuel gauge is not acting up like it use too. you know when you have half a tank of gas and the needle say's your empty and slowly climbs up.

 

Just had my dealer change the filter. 30k miles on a 2001. Cost close to $150 but I don't have a lift and my old bones can't stand working under my vette. Watching the mechanic change the filter; looked like a PITA.

By the way...those of you looking for good dealer service in northern CA(good not exceptional) consider Jimmy Vasser Chev in Napa. They haven't messed up yet and so far all work has been as promised.

Talked to old man Jimmy while I was there re C6 Z06s. Says he's getting two. He'll keep one for himself; says he's getting offers from other dealers for as much as $20k over MSRP (not invoice). Bought some lotto tickets

 

SteveGel,

Thanks for the instructions!

Nice write up,i'll be doing mine in a week when i install my headers.

 

Nice write-up Steve!

However, I thought some of the folks here may not be aware that GM totally redesigned the C5 fuel system in mid model year 2003 to accommodate future LEV 2 emission requirements. This was accomplished by moving as many components and fuel lines as possible inside the fuel tanks, to minimize hydrocarbon emissions. In the new system, the fuel filter is part of the left fuel sender assembly inside the left fuel tank. The left fuel sender assembly also includes a fuel level sensor, the fuel pump and reservoir assembly, the fuel pump strainer and the primary fuel pressure regulator. For the redesigned system, there is no service interval for fuel filter replacement according to the 2003 GM Service Manual.

For 2003 Corvettes only, this system was designated by RPO code FFS. However, this name has been unofficially applied to all vehicles with the new system. For those owning model year 2003 C5s, you can tell if you car has the new system by looking at the Service Parts Identification (RPO) label on the inside of the glove box lid. If so, you will find RPO FFS on this label.

You can find more info on the redesigned system at the Following link:

Redesigned FFS Fuel System

Hope this helps.

 

Might as well cover all the bases then,the 97 - 98 cars don't have the fuel filter and regulator built into one unit,and the filter is located at the engine.

 

Nice writeup and great pics

I bought the filter a couple months ago and didn't get around to the install and then got hit so it's been sitting in the body shop for the last 6 weeks. When I get her out next week it's probably as good a time as any to do the switch. I saved your writeup and it will certainly help.

 

Nice write up - thanks.

 

tote the filter to the shop and have them do it..

 

and miss all that sweat, cussing and aggravation?

 

Is not the filter located by driver's side rear wheel on the frame? Regulator is in/by the engine.

 

The filter is back there on the driver's side where you say. Just FYI, the one I got from O'Reilly's wouldn't fit in the metal loop that holds it onto the car, the filter was too big around. I had to get the GM filter. I didn't care to come up with a custom bracket at the time.

 

Wish the pics in this DIY still worked :/

 

5 1/2 year old threads tend to do that.

 

I changed mine, took me about 1/2 hour
Don't forget to bleed the fuel pressure off at the schraeder valve on the left fuel rail or you'll have gas all over udner the car
