Default Dual fuel pump setup?

I currently have a single walbro 255 in tank, I'm looking to do a dual fuel pump setup but have no idea if my logic is correct. In order to do a dual walbro 255 is it as simple as installing a "y" Help me fix my misconceptions please.

Hooking the lines up is only part of it. You need to properly power the pumps & install the components in the tank to prevent fuel starvation & pump failure.

I provide a complete kit that uses quality Racetronix components for long term reliability. This kit is fully assembled in your sending unit & tested for proper operation before being shipped.

Please let me know if I can be of any help.

Which kit is it? Being a newb at this I'm going to need to know which part of the fuel system parts list would be best for my application. I plan on using stock fuel rails.

Default I might need one also

I have a 01 ZO6 TT with a 388ci that when I get on the throttle the pressure goes from 62 to 57 on low boost. It is in the process of a major rebuild so don't need this right now. It does have a Boost-a-Pump on it. Duty cycles on the injectors were 94%, so we are not sure if pressure is too low or injectors are too small or both. I am assuming you would have a unit for my car. What kind of pressure are your units holding?
Thanks,
Jeffy'

I have supported over 900rwhp with my twin setup. Depending on your HP levels, you may also need lines & regulator to suport the power.

I do have a kit for the C5 Vette that is easy to install in the stock tank.

Nothing like plug and play-the kit is as complete as it gets!

eb02z06,
Thanks for the kind words & also for the testing on my prototype C5 kit.

Did you ever get back to the dyno? It seems the 885hp in your signature is outdated.

I'm pretty sure it can be 1000 rwhp tested but i'm afraid my block may give up before your fuel system Lonnie.

Lonnies dual in-tank kit is awesome. I am making 914 rwhp on 15 lbs of boost with 60 lb injectors on his dual in-tank setup.

Lonnie, are you offering just the wiring harness yet?
I don't need pumps or lines.

To all....
Glad you are having good luck with them.

I am putting together a showcase for all interested customers. Please provide some pictures & car info (mods, dyno & track times) so I can show the fuel systems performance potential while allowing a place for everyone to display their pride & joy.


As for the harnesses, I made an agreement with racetronix not to sell them independently.

Yes but you will fry the factory wiring with 2 pumps drawing. It is also impossible to just sell you the wire harness as the stock bucket is modified for the new wiring and all the pin outs are different then stock.
