Posted this in the Nitrous section, figured it would be more appropriate here...

We are playing with a 2003 Silverado, slipped in a cammed LQ9 and few other bolt ons, and spray.
We need more fuel pump. Options appear to be fairly limited compared to the f-body world.
Want to do an in tank setup. $600 for Lonnies double pumper is a bit overkill.
In line is ruled out.
I have not found a direct bolt in deal, like a Racetronix for the trucks.
I don't want to hack up the bucket for a Walbro, and loose the bucket feature.
Has anyone used a 99-02 f-body Racetronix pump to work with the trucks? Is it even possible?

 

Any ideas?

 

Why not run a inline??? There isn't a direct bolt in that I am aware of, alot of the guys went with a double intank setup or a big bosch like I did, which means bucket mod, the double intank is $$$ unless you plan to do it the big intank just takes some time to mod the bucked.. A inline would do fine for that

 

I agree...even the Magnacharger in-line with the stock in-tank is good for 500-550RWHP on the return style (03) 6.0L. For roughly $140, it is a complete kit and can be installed in a matter of minutes.

 

I just have a hard time understanding how the inline's can work well.
You are relying on the stock pump to feed the inline?
Or is am I looking at it the wrong way, and the inline is there just to boost/maintain pressure under high load?

 

You can do it boost ref if you want off a switch, or you can run it all the time.. It will draw through the stock pump...

 

We ended up ordering the Magnacharger pump kit. Thanks guys.
