I am planning on an LS7 swap in my 96 Z28.
What would be the best way to upgrade the fuel system to handle 650 HP?
Is there a single in tank pump that can be fitted in the OEM Bucket big enough to feed the LS7 or should I go with two walbros and loose the bucket?
Would adding an external inline pump be another way to handle this?
Open to suggestions.

Ive done some resarch and am leaning towards the BOSCH 044 pump installed in the tank.
Anybody here done that install?

Not sure if you mean 650 flywheel or rwhp...

I can offer a single Racetronix pump kit that will support 550rwhp (about 60 flywheel) or a dual pump setup capable of over 1000rwhp.

I offer the dual pump setup as plug-n-play, assembled & tested product, to save you the work of trying to build it yourself.

You can use the 044, but all the internal & external tank wiring will need upgraded for that larger current draw.
It also will not fit in the factory plastic bucket.

Let me know if I can be of assistance.

Thaks for your reply .
the engine is rated 650 FWHP. I do have the walbro 255 pump upgrade installed in my car. I have read that these Walbro pumps run out of steam at about 450 WHP and am looking for alterntives.

Do you think that the Racetronix upgrade can support the LS7 without fuel starvation? I have not installed the hot wire kit yet, just the pump in the bucket.

The stock pump will support approx 450rwhp.
The 255 about 550rwhp.

You need the hot wire kit for the bigger pump.
Personally I never install a pump without the hot wire.

Thanks Lonnie.
I will try the Walbro pump with the hot wire before throwing the bucket away.

Ok Lonnie so what would you suggest if I already have 1 walbro with the hotwire kit installed but now need a second pump do you sell a kit for this situation? Or would I just need to get a 2nd pump and what a T fitting to run them together?

If you are at 650 flywheel, your will be ok on your present pump.

I sell a complete dual pump kit as your current pump is different than the duals that I use.

I can get you the components to add your own 2nd pump if you desire.

I do not recommend 1 hotwire to feed 2 pumps.
Also I do not run both pumps continuously (nor do I recommend this), so you will need more feeds than your your present hotwire provides.
