I was changing the tranny fluid today on my dad's 04 Z06 and thought it would be a good time to change the fuel filter. I thought for sure it had one because I rembered seeing one on a 99 FRC of a friend of mines. The fact that a guy at Oreilly's sold me one lead me to believe that the car has one, but once under the car I searched all around the fuel tanks tracing out the fuels lines with no result. The only reason I'm asking is because I own an 04 Chevrolet Silverado that does not have a serviceable fuel filter. So if anyone knows if the car has one, where its located, or perhaps the correct part number it would greatly be appreciated

i am pretty sure that it is inside the fuel tank. starting around november of 02 they started putting them inside and before that they are on the outside of the fuel tank.

Supposd to last forever, Just like the plugs dont have to be changed until 100,000 miles. LOL Good thing I own a 01.

basically I bought a fuel filter for my 04 Silverado for nothing?

If you jack your Vette up and remove the rear wheels you'll see the easy access plates to get into yor fuel tank. Make sure your below 1/8 of a tank. E would be best. There are tank covers there infront of the wheels, remove the rear four, and only loosen the front two, that will drop the dust cover, and expose the access plates... Let us know if you need any more help..

So from what you guys are telling me. It has one but can only be replaced by changing the whole fuel pump assembly???

Can this be done on the 04+ C5s also? Cause I was told that the tank has be dropped to get to the pump/filter on those newer fuel systems.

No this cannot be done on a 2004. The fuel tank is different. The access plate is a the top of the tank. You have to drop the tank. Even if you did this the filter is incorporated into the fuel bucket/pump and you would have to replace the whole assembly..Major $$$s

Does anyone have any pictures at all of the tanks?

Also, if the C5 uses dual pumps how does it feed the engine? Both run at same time?

C5 only has one fuel pump, its in the driver side fuel tank..

If it has a single pump, how does the fuel in the passenger side tank get used?

chriswtx

iTrader: (5)

they divert a little fuel pressure fropm the drivers side fuel pump over to the passenger tank into a ventury. That small flow creates a syphon effect the continually syphons fuel from the passenger tank into the drivers tank keeping the drivers tank full...

I don't know if your yanking my chain or not. I can't seem to find much info at all. I'd like to run 2 small fuel tanks on my car. I was thinking of something simple like this:

The supply line of the passenger tank is tied into the return line from the regulator. The pressure/force of the return line creates a syphon/suction affect on the supply line of the passenger tank and pulls fuel over to the drivers side tank. If there are more than 8 gallons of fuel, then the extra fuel pulled over to the drivers tank spills over to the passenger tank via the fill/connect tube up top.

here is the 2004 vette setup...

JasonWW

So the tanks are connected over the driveshaft so that once the first tank gets around 8 gallons inside, it starts to spill over into the other tank?

I was thinking ov just connecting the 2 tanks under the drive shaft with hard line and adding a brace to prevent the driveshaft from dropping down should a u-joint break.

Boy. I am not sure if it is improved for the 04+, but it is sure more complicated....

Correct If the tanks are both empty and only 7 gallons are put in , there will only be gas in the drivers side tank. If 9 gallons are puting in, then 8ish gallons will be in drivers side and 1ish gallon will be in the passengers side.

Damn, it's going to take me a while to figure out how everything works. My idea is a lot simpler.

I'm guessing it uses the computers brain to calculate the total fuel based on each senders position. See, I can't do that. I would need to have the fuel levels in both tanks go up and down at the same time in order for a single sender to work.

I suppose I could always run 2 of the stock sender/pump units in each tank and have a toggle switch choose the tnak I'm running on. That's old school, like a lot of trucks use.

Or I could mount a simple pump in the extra tank and use some kind of switch in the main tank that would turn on at a certain fuel level and then turn back off. Then a switch in the second tank to cut fuell pump power once it's empty. That would make the gas guage read funny though.

I could also just manually flip a switch when the main tank gets low to activate the second fuel pump and transfer fuel from the second tank to the main one and then switch off the pump when it's done. I'm not too keen on that as I may accidently leave it running.

Any ideas on how you guys would plumb dual tanks?
