Default Stand alone fuel system

Im interesting in looking into a standalone fuel system... But have no idea where to start looking... Any sponsors on here offer such a system? Thanks!!!

A couple fuel system upgrade write ups in my web in sig, options for avoiding the stand alone. Actually, mine is a dedicated fuel system.

Robert I haven't been to your page in a while but it looks good! looks like a lot of work and time spent to help people out. For f-body guys I am always hesitant to add an inline when a good pump and harness are already in the tank for fear of pulling the bucket dry (obviously no concern on a 98).

Personally, with rails, front mount reg, walbro, harness and booster it has been hit or miss for me to see 600rwhp on the dyno I tune on. On my own car, even with meth (turbo so a lil different, but assuming we still target mid 11s AFR) and that setup mine was plain out at just over 600rwhp with fuel pressure in the 30s at that point.

He will be making good motor HP, milled AFR 205s, g5x3 on a 114, supporting boltons, etc ., and a wet shot worth 150 at the tire or so. I recommended the stand alone also because I don't like the hit that the rails take at that level.

None of this is in stone though, except for the racetronics pump and harness already in the car.

PS. there is a trap door too, so it's easy to get into

The second write is dual pumps in the tank, and good for about 1000hp, IIRC. Why would the bucket be pulled dry adding an inline, am I missing something? Set-up like mine, you'll pull directly from tank, not causing issues with the bucket, at least on the Vettes. Sure seems as though yours should be good for over 600hp? My buddy is running a non return stock pump with a BAP and is currently running 665rwhp, yes have seen it on the dyno and at the drags. Maybe, your not getting the voltage that you should? Check for good grounding?

I don't think you realize the differences in the F-body and vette systems...

Well why don't you school me and those that are reading along and wondering, the exact differences between the Corvette fuel system and the F-body fuel system? The Vettes do have a bucket scenario also, but only effects the in tank pumps. I think it's mostly dependent on where you plumb your additional pick up fitting (down low and towards the rear). Like I said above, am I missing something? Or is it that you don't understand how an in-line set-up works, as F-bodies do/can in fact run in-line pumps? We are talking a complete additional fuel system, only tied into some of the stock components up front in engine bay.

An inline second source outside of the bucket is fine. A pump inline with the pump in the bucket can overdraw the bucket. I understand what you are saying, but many reading need to understand the difference as it may not be clear in the previous post alone. The only difference in such a setup as opposed to the front standalone is you nix the tank in the front. Your first post was about avoiding a stand alone so I guess it wasn't what I was expecting.

As far as my own setup went, the nitrous goes a little further fuel-wise than FI, but not a large stretch. It's cool your friend made high 600s on a stock pump with a booster, just saying that the F-bodies don't seem to be able to pull that off even with replacement-pumps and harnesses.

I had an 03 z06 with meth and a BAP/stock run shy in the upper 500s, and an 01SS with a pump/harness, meth, and D1sc (M6) ran out in the same place. All returnless of course. Just pointing out the differences in the pumps and systems as OE. I'm sure you are aware of all of this, I'm just want it to be clear for those reading who may not realize there are differences.

Yea in my web I explain things a little more in detail. IMO, the biggest thing to do is to get the return and reg at the rails, very important and goes a long way in extending stock or aftermarket systems. Yes, the FI guys really need the best fuel system possible. I don't like the stand alone fuel system for a few reasons, mostly it's not needed with an upgraded stock system utilizing stock tank in many ways. the dual pumps in stock tank support 1000rwhp, but again we need the reg/return up front. Also, the watered down mix in using a stand alone is not good for guys serious about spraying, and i want the full octane for my hits and thus the stock tank. Thanks for expanding on the info presented.
