Default Fuel Pump Differences

So because my fuel pump went out i am learning way too much about the wrong "facts".
I knew that there are 2 fuel tanks in the C5s, but i didnt know it had 2 fuel pumps... 2 DIFFERENT fuel pumps.
I really dont want to pay the dealer $1000+ to do something i would have no problem doing.
I also know that the 2003s used a different type of fuel tank, so the pumps are different.
But other than that are there any differences between the fuel pumps for the different years of C5s (97-02)? I have a 99 corvette, the fuel pump in question is for a 2002. Would it work?

The 99 and 2002 are the same. Yes, get the racetronics set-up. cajundude at vetteforum has a how to write up on changing out the pump, easy job.

you can't search for cajundude without registering.

Do they show any pics of the fuel tanks? That's all I really need anyway.

Early 2003 models still had the older tank. YOu might want to check into that. Racetronix is ok, but its glued together. LPE makes a nice pump set up that is pretty much plug and play.

As far as I know, the 99 and the '02 are the same pumps, stock GM supplied Walbros. The Racetronics and LPE are also Walbros but a little better and a higher HP capability. the stock pump is mostly considered good to 500/550hp. Here is the link:

Where in the world did you get this misinformation????

Our kit has been bundled with the Walbro/LPE GRJ420 assembly for a number of years now. Nothing is glued in our C5 kits. We add some upgrades and improvements in our ad and sell them in kit format.

LPE carries our products and we carry theirs.

HAPPY HOLIDAYS

An '02 fuel pump will work in a '99.
This is what it looks like before the bucket is assembled.
This pump will not work on 2003 ½ and newer fuel systems. This would be the VIN after 114930 (last six digits) built November 25, 2002.

Glad to know things have changed and are going well for you guys.

I have no problem with your kit. It works well on my buddies f-body. In the past i saw one come apart in a corvette. **** happens. Im a big fan of my LPE pump as it took less then an hour to put in my z06.

What are the hp capabilities of the racetronix pump?

Nothing has changed other than the model number on the pump. We never used or included glue with our C5 kits. Perhaps you are thinking of the FLT1 kit where the factory bucket must be re-used and sealed back up? This has nothing to do with our C5 kit where the bucket snaps together and comes pre-assembled.

Perhaps you are confusing different aspects of different kits for different vehicle platforms?

The Racetronix C5 pump assembly is the same GRJ420/LPE unit with the added benefit of the new in-tank wiring and upgrade harness.

I forgot to mention that I run a Racetronics pump/hot wire kit in my Z06, and you can see the 600+ rwhp supported in my sig.

Perhaps you are right, and im just being retarded.

What are the HP abilities of your racetronix pump? Im kind of considering switching from the LPE pump to the APS fuel system as I have a twins going on the car with a built 402. I fully expect to run between 600-700 around on the street, and over 900 on the race gas.

You would require a dual in-tank system at that power level.
Stock lines can easily support 700HP but you should convert to a FM FPR setup.

wow, who dug this up?
i found out that the pumps may be the same, but the assemblies are different.
one model has the bolt holes spaced evenly, the other has half of them close and half of them spaced further
I wish i could go more into detail, but it was almost a year ago.

Do you know who makes a setup like this (the dual in-tank system)? I have an early production run 03 z06 with the pumps coming out the side by the rear driverside wheel.
