Fueling & Injection - 2002 Intank fuel pump recomendations

Best plug and play in tank fuel pump setup for a 2002 ws6 . Needs to support 550 - 600 rwhp ?? I like the sound of the racetronix setup but its only for the 98 cars . Why the hell would they do that :confused:

Thanks :hail:

Because the 98's had steel gas tanks, and all other years have plastic ones (or did i switch that around?)

Most people opt for the Walbro or Holley 255's

Is here a write up on the instal availible ?? Im a tad bit concerned with screwing around on the fuel system .

Also which one is the best quality ??

the search button is your friend ;)

I chose the Holley, I think they are pretty much the same in terms of performance.

Holley uses a Walbro pump. I keep them instock for $120.00 w/ install kit. 02 is a little more involved than that and should be done by a shop.

Why is the 02 that much different? I was going to try and do it myself.....hmmm :(

What he said :werd:

I wonder why nobody makes a plug and play fuel kit for the 99 up fbodys .

ya why is it so hard to do?

running the walbro 340m on my 02 35th.no problems here even on a 150shot.

ya why is it so hard to do?
Because it requires a special type of pump that will work in combination with the fuel module's venturi system which keeps the pump immersed in fuel regardless of the level of fuel in the tank.

Everyone that is installing a standard Walbro pump is doing away with this function by punching a hole in the bottom of their fuel module so that the pump has a supply of fuel.

It is a compromise but sometimes you can not have your cake and eat it to.

But then again a chef might have a cake in the oven...

Does that mean your going to have a plug and play fuel system availible soon for us ?? *crosses fingers* :)

why have i never heard this before? i've never heard any mention of an 02 pump being different? When i bought my Fuel Pump no one ever asked if it was an 02 or not....

I'm not saying i don't believe you, because you are obviously versed in the matter...but this is the first time i'm hearing about this. What is this fuel module that you speak of?
Thanks,
Mike

I'd like to hear some more info on this too. I just bought a Walbro 340 for my 02 Z28 and this is all news to me.

Thanks!

Are we planning on a solution? YES
When will it be available? No set ETA
Should you wait for it if you need something soon? NO

I will try and find a previous thread detailing this information.
If I can not find it I will put something together again shortly when I have some spare time. It has been unusually busy here since the new year.

cool, thanks very much. This just comes as a shock to me (and some others i see)

can i just an the bosch big inline pump and me fine for a 150 shot on a 500rwhp car?

Walbro pump in my 02 with no problems here. I might go with a double pump when the turbo kit is installed. I'll do it myself instead of buying a kit. The other option is a boost a pump.

The people that are running Walbro 340's in your 02 cars...

Did you install the pumps yourselves? What all was involved? Any special steps?

Please hurry some of need a solution in the next 4-5 months. :usa:

The pump is not different at all , the only difference is the sending unit . I installed mine myself , it was intimidating at first , but I just did a bit of research on the net with what other prople are doing and it was a snap , had it done in about an hour and a half start to finish .

So you've installed an in tank pump in a 2002 model car?

Chad

No , in a 99 , but they are the exaxct same . 99-02 F-bodies are the same .

I thought the whole point of this extended thread was that the 02 cars were different.

Did I misunderstand? I thought when Racetronix posted the following it was for 02 specific cars:

Because it requires a special type of pump that will work in combination with the fuel module's venturi system which keeps the pump immersed in fuel regardless of the level of fuel in the tank.
Everyone that is installing a standard Walbro pump is doing away with this function by punching a hole in the bottom of their fuel module so that the pump has a supply of fuel.

Is this just the 02 cars or was he talking about all 99-02 F-bodies?

Chad

99-02's are different then the 98 . You misunderstood , but he did not make it completely clear either .

There have been some cars reported as having metal gas tanks as late as 2000. As a rule the car's equipped with metal gas tanks were mostly in 1998.
The current Racetronix system only works in the F-LS1 cars equipped with a metal gas tank.

The F-LS1 cars equipped with plastic tanks all have fuel module which uses the venturi fill system which only functions with the factory pump assembly.

can i add on an inline pump and be good with runing most setups

when would i ahve to go to an intake pump?

Why would GM just out of the blue , throw a metal gas tank in 99-02 f-body when all of the other ones had plastic tanks ? Where was this reported ? I am just curious ...

We have seen one at ARE and have had similar reports from other dealers.
Why would GM change fuel modules in a C5 half way through a production season?
This is not so uncommon but generally these deviations are with less visually obvious items. That is why it is always best to supply a VIN when buying parts for your car as oppose to just the make and model year.

For those who haven't been following this I've included some links to old threads. If you can wait, the Racetronix system will certainly be the best single pump intank solution.

I am runing a intank 255 and no problems at all. I ran a inline and it wasn't enough. So now I have both. My buddy and I did the install and didn't remove the tank. Works Great.

i just dont feel good about cuting up my 2002 ws6

Drop the tank once and your opinion will change. Installing an access door was SO much easier plus nobody will ever see it since its under the carpet. I had to take my pump out 3 times! If I had to drop the tank that many times, I would of died. GM should of made an access door for the f-body.

An inline pump will still be limited from the restriction on the stock pump.

Just take your time and it will work out fine. As Rodent said, it is WELL worth doing. Remember that the 2002 unit is located back further than the the 1998 pump unit. Search for pictures of both (they are on the board somewhere) and you will see the difference.

-Ken

The 99-02 are the same it is just getting the pump to sit in the plastic well correctly that is dificult.

A inline pump will not do you any good itcan`t pull more fuel through the pump in the tank than that pump is capable of pumping.

Have a GS340 in my 2002 Formula. Install was a bit tricky. It was not a direct bolt in. I had a shop do mine. Pump was 100, install 150.
Works great so far. (2K Miles)
