Another Fuel Question... Will my tank work with my setup...
Hi Guys,
I have another question for ya...
With my 383 + Procharger + fuel injected Setup producing about 600+ at the wheels... will I still be able to use my New Stock Gas Tank Replacement and just ugrade my fuel system by installing "out of tank" pumps, etc... to keep my fuel system performing with everything else?
Thanks,

With EFI though any hiccup is immediately felt.

Thanks for the reply Jody...
When you say baffled... Are you referring to a sumped tank?
Since I've decided to go EFI, maybe I'll need to go back to my old idea of using the area on the car that's already prepped for a fuel cell and go with this unit....

No I think he means a tank like Ricks makes with internal baffles in it. I have a stock tank with a sump and if it gets below 1/4 tank it will start hesitating under hard acceleration. The baffles in the tank stop this. I am cheap but ive decided that the ricks tank or something similiar is a necessity and it will be my next purchase for my car. I like the new setup Ricks has with the Bosch in tank pumps i definitely will go that route after my Aeromotive pump left me sitting on the side of the road on the Powertour.

I see... Thanks for clearing that up for me...
So a Sump alone will not cure the hesitation or starvation once the fuel level begins to drop?
I'll check out Rick's...

Mine is sumped and it still hesitates when its low. Possibly the way they position the fuel pick up and the in tank pump set up helps. There is a topis about fuel problems on the Power Tour on Lateral-G.net

It has alot of good info and explains some of the problems some of us had on the Power Tour.

This is the new dual pump set up that Pushrod was referring to. If you look at the pictures you can see that the pump actually sits in its own seperate chamber. They will still let fuel in and out but they dramatically decrease the amount of fuel moving back and forth. We took advantage of the fact that the tank naturally tapered up as it went rearward. So you could say it its like a reverse sump. The fuel has a natural tendency to go to the lowest part of the tank in this case the chambers. Once in there you can rest assured weather youre moving hard in a lateral or longitudinal direction the fuel will always be there. Keep in mind that it is not recomended for any in-tank setup to run it with less than 1/4 tank.

I can confirm that a sumped tank like the one pictured will not be enough to keep fuel by the pickup. You can go with a baffled tank like mentioned or another option is to use a surge tank for the EFI pump. You supply the surge tank with fuel using a carb fuel pump and because it is long and narrow the feed at the bottom will always be covered with fuel for the EFI. Adds complexity, another pump to buy (and fail), and more hoses, but it does work very well. Even some factory EFI cars have issues with the fuel pickup at track days.
Here is a link on how to fab one. http://toyotaperformance.com/surge_tank.htm
