I have been researching all the different fuel setups for making 800-1000 rwhp. Seems like it comes down to A and As external pump setup, ECS, a home made setup using (aeromotive fuel rails, aeromotive boost references regulator, bosch or Aeromotive 1000 pump and lines and fittings, Twin Walbros ( in tank??? not sure on this one) and APS in tank unit.
Can you guys elaborate on the twin walbros and how you mounted them what other components it consists of.

The problem with in tank twins from my experience, is that when you loose the canister, which the fuel is returned into, you create air rating problems. The canister keeps the fuel from sloshing around the pumps, and keeps a constant reservoir. When the pumps are dropped in without one, on a heavy launch, all the fuel slams the back of the tank, and your not getting constant fuel feed to the pumps.
The major problem with this is that you will still have fuel pressure on your gauge since air will compress, it just makes for inconsistent lean conditions when you need it most.
This is why we utilise our separate -8 feed, and -6 return block, which is mounted in the lower rear of the tank. The pump comes on under boost only, so there is no chance of you hearing anything other then what you did stock.
Our stage 1 can support 900+rwhp, and the potential to grow to 1200 hp+ is there with what you already purchased, just by increasing pump size and rails.
We have been utilising our system for many years now, and it has been more proven then any other system on this forum today. We have the personal experience to be able to tell you exactly when you will need to upgrade, and what is needed when you do.

I hope that helps save a few engines.
Thanks Doug that is very valuable information and helps me make a better decision! Makes sense as all my old cars we always ran fuel cells with sumps so it never ran dry, a return line and jet extenders and notched bowls for when the fuel sloshed back in the carb it wouldnt bog. Once again for me just converting that to todays technology.
As with anything its better to do it right the first time, make even over doing it is better. If your attempting a 800hp+ the twin in tank pumps will work as long as you dont decide to go for more. I have twin walbros in a aps bucket in my tank, it ran out of fuel at 850hp. If thats your goal you will be fine, if not I would go to one of the many reputable dealers here and discuss your needs and they will take care of you. I like Dallas Performances setup, I dont use it but Taylor has always been very helpful. If you go with the twin in tank pumps and decide later you need more you can always do what the guys at LMR did for me- its crazy looking but it works. The in tank pumps feed the surge tank in the picture and the magnafuel 750 feeds the motor.
I will warn you though that route was expensive. So in my opinion I would spend the money now for a complete 1000hp fuel system.

Nice setup Then it becomes for me that we keep adding more weight for this , more weight for that. I was ok with adding the SC and now using an LSX block but more weight for an additional tank....pretty soon its gonna outweight my diesel Thanks very much for the input. It all helps in my final decision
Tried and true, alot of 1K rwhp cars have been using this setup. I don't like the idea of going in the tank to change out any pump. Escpecially the way they are set up, it's a Biatch to get to. Just my .02 Good luck.
The Dallas Performance fuel system is a great system, and is rated to 1800hp. You could also save some money by going with their 1000hp system. That is what I'm going with.

Imitation is the purest form of flattery
That setup, is the ONLY way to go. Period.
