fuel system for 99-02 plastic tank
Whats everyone using for a fuel system on these non baffled plastic tanks for HPDE and AutoX? I know Racetronix supplies the 255l drop in pump for the bucket but I have that and my tuner is saying I'm still not getting enough fuel during WOT. I have a heads/cam LS2 installed at the moment but plan on going FI and I'll really need to bump up the fuel supply when I do that. Any ideas?

Injectors maxed out? Maybe call Racetronix and speak with them about options? I feel a 255 seems to cover a wide range of setups. I wouldn't think a HCI LS2 would max out a 255. I could be very wrong though.
Is the car not getting fuel at WOT on the dyno or during cornering?

I'm piecing together a system with a second venturi boost pump with a walbro 450lph pump at the moment. Hopefully I can get the factory venturi to work along with the second. I'll post up my results when I'm done.

You wont find a larger pump (yet) that uses the jet pump system than the 255. For road racing that is a nice setup to have. With stock fuel lines the racetronix will support 600 na hp. looking for less than 12.3 afr will bring that down, and running e85 will not make 600 na on it. For boost, youll want the dual 255 kit. We have the whole kit with pumps and harness for $429 BUT the stock fpr inline wont work so youll need to address that somehow. We can help with that also with the racetronix complete fuel system ($575) comes with boost ref fpr also. That will handle up to roughly 800 at the wheels. above that the dual 340 will do 1k.

There is no doubt the stock fpr wont keep up.
Its not made for E85 either.
The 450lph pump needs more power, and we carry the in tank harness for them. a single 450 with a constant 12+v would keep a pretty fat afr fed or e85 but its pretty taxing. Running duals evens out the load BUT you dont use the gm style bulkhead anymore.

Man if you carry the higher amp bulkhead connector you need to list it on your website... unless its not under racetronix as the manufacture. The only place I could find it was racetronix website... and my order is still just sitting there paid for and not shipped since Tuesday.

We sell everything racetronix sells as well...but they keep adding more parts and its hard to keep up PLUS we are transitioning to a brand new site AND taking care of all the pricing updates and new product offerings it can be hard to catch everything. We will add both bulkheads on the site asap though. I do know they were on back order for a bit...so that may be why it hasnt updated with info. They do come in every new racetronix hotwire kit as well if that helps any.
We have sold prob 5 individual bulkheads this year, most of the time the customer has no idea what its called or we get tech calls that finally lead to that issue. They are a good piece, they just take some adapting to work if you dont have the new harness etc to work with them.
