what do you think?? im at the point were i need some more fuel but im very tight on money right now, author member on here has the procharger in line kit for sell , and i thinking of getting it and adding it to my setup that i have now, witch is just a in tank Walbro stock lines with 60s, my car made 524rwhp at 5500 and rau out of fuel im thinking that if i add this other kit ti should do what i need to to do, what to you guys think?
Since you are funding limited, dualing Walbros. Read the stickie at the top. If you go inline, the intank will still be a limiting factor if understand your question correctly. And a boost a pump is a patch, at best.

Verdad Gallardo Some just run both pumps all the time, but I would not do that myself.
60lb injectors, 255 intank, 255inline, boost sense fpr, gutted dampner on fuel rail, crossed fingers and a lot of meth...around 175lbs/hr last time I calculated. My afr via WB is deep into the 10's and that is where I keep it. I only post this because I couldn't run the boost I do with out the fuel for sure but more importantly not on pump gas without the meth...so I killed two birds with one stone. I am sure a second 255 pump would be more reliable but again, wouldn't work for me.

No I bought the pump second hand and it had the fittings to plug into the filter/intank pump out line, basically replacing the piece of factory fuel line from the intank pump outlet above the rearend to the back of the filter......I think, it's been awhile since I was under that part of the car. Then I just ran a wire from the engine positive post to a relay back there so it gets full voltage from alt. Relay is of course triggered to come on when intank does via the same wire. Intank pump has a separate relay for the same reasons mentioned above. My thoughts were intank provided flow and intank maintained pressure....I have yet to see a drop in FP with this set-up fwiw.
Again, if memory serves, I set my base FP to 39psi which is where the mototrons actually flow the 60lbs/hr...at the factory Ls1 pressure, the mototrons really flow 83lbs/hr....I think....can anyone confirm this? I did this because of the boost referenced fpr which I put in place of the factory regulator (been removed) and factory return line, then of course ran a vacuum/boost line to the back. I think I have pictures on one of my webshots but can't view the site from work to be sure.

Buy a wiring harness and 2 walboro's, put them both in the tank. Remove the FPR, install a boost mounted reg w/ a hobbs switch up front for the 2nd pump. Remove EVAP and use the evap line for a return. There are some details in the fueling section on this setup. This can be done for fairly cheap especially if you have aftermarket rails already. Works fine for me an many others.
I'm making ~600 rwhp through an auto with it. I don't think I'm even pushing it yet.

I'm not sure if your cars stock fuel system is different than my C6 but I'm putting down 625rwhp and all I am using is the Kenne Bell Boost a pump. I'm still runninng a 11.5:1 A/F and maintain 61lbs on the gauge. i do have 60# injectors as well. The Boost a pump is only around 350 if i remember correctly. I also have a few friends with boost a pumps putting down over 750rwhp without issues. Just a thought

A rail mounted fpr will help alot,how far im not sure. But I run -8 lines 2 walbros -6 return and a fpr on the rail numbers in the sig. I think for you a rail mounted fpr will help squeez alittle more out with out the other pump. Plus my set up each of my fuel pumps have their own feed line. I max out my turbo befor my fuel system needs an upgrade.
I'm In the same boat you are, 543rwhp with a walbro intake and a hotwire kit I was at 20psi of fuel pressure at 5,100rpms, Removed the hot wire kit bought a KB-BAP and now at 6,000rpms its starting to drop to 35psi. Going with lonnie's dual walbro's with a hobbs switch in a month and this better be the last time I pull the tank!!! The dual intanks is what every ones advice to me has been.
