Fuel System Help - Should I...
fuel system is a biggie...
the aeromotive A1000 kit is damn expensive, but complete down to wire ends and ties - pretty much requires a sump or a fuel cell...
i could cut corners and save cash - but i wanna do it right
i'm almost sure an upgraded in-tank pump would support my motor (427cid, 12.5:1 - ~600hp) - but that leaves the issue of new lines front to back and a regulator/bypass with a new return line. some people have done it and replied to my other threads but seem to have some wierd fuel issues (using stock lines). that is one thing i want to try to eliminate and will pay good money to make sure it doesnt happen.
at this point, i am unsure of wether or not i want to keep the interior stock. rearward of my seat i could really care less, so a fuel cell wouldnt be too bad to make work. however, i could either sump my tank or a new replacement tank and go that route (if there is room). that would allow me to keep the interior in one piece if i so chose to do so.
What are some of you big horsepower guys running...and would you have any good suggestions as to which direction i need to start looking?
so far on a pump and bypass regulator with fittings from aeromotive i'm upto ~$520 bucks not counting fuel cell or sump kit. this is no lines, hose ends, etc...just pump, bypass regulator, and the fittings for all the ports on them (with a gauge)...
Buy it and drop it in the tank and away you go.
I put mine behind the license plate,but it will fit in the tank.
You need 2 # 10 lines and fittings.I drilled a hole in the top of my tank and installed through tank fittings.I installed the return line on the right side of the sending unit.I had to do a bunch of grinding on the sending unit to make the # 10 fitting fit where the old fuel line went but it can be done.Be carefull not to damage the sending unit for the gas gauge you will hate life.I left my old metal lines in place and just removed the ones on the passenger side at the frame foward and ran the lines down the pass side of car.It is a little tracky to mount the lines and route them over the rearend just take your time you will figure it out.
I made a bracket at the radiator and installed the fuel regulator their so it would stay cool,and it is easy to read when adjusting fuel presure.

the A1000 is an external pump i thought? and it pretty much has to be mounted toward the bottom of the tank along with your feed so it stays primed...kinda like my computer watercooling...or just the pump feed has to be coming from the bottom of the tank?
so did you pseudo-sump your stock tank...or just drill for a fitting in the bottom of the tank and call it a day?
i know the return's gotta go in the top, so reusing what was there ws prolly an easy move overall...
i'll have plenty of room in the engine bay to mount things and tidy it up...so that's not a problem. i figure i'm pretty much gonna need to come up with my own radiator and fan shroud...i kinda think i fubared mine (no pun intended)...
I just removed the line from the sending unit that the fuel line comes out of ,drilled the hole just a little bigger and cut a bolt in half to install the throu fitting it is a tight fit against the fill neck but it can be done.That took some time and you can't make the hole to big.You can buy all the stuff from Russell that is easier.
Yes this is an in tank pump believe it or not.
These are Aeramotive words on the 3 line of the instructions and adds.
Fully submersiable for custon ,in-tank placement.
yes it does fit in the tank.
The pick up is a little diffacult to install because the tanks are round,fuel moves to the top of the tank when you accelerate.
I was lazy ,so I just installed 7 pieces of foam in the tank to keep the fuel from sloshing.Be careful the foam only lasts about 2 years and starts to break down.
Any other ? just let me know!

If you look at the pick at the top ,on the left side is the line to the pump from the tank.The one on the right is the return line,I just spray on top of the foam on the return .I taped the throu fitting and installed a 1/2 copper line and bent it into the sump stock plastic pick up where the old pump went.
The pump has to be lower than the tank .

thats the instructions for the A1000 pump. you are correct about having a minimum 10gal or 1/2 tank in the tank if you use a pickup instead of a sump...but it mentions nothing about being submersible. i wouldn't feel comfortable even trying. i'm sure they do make such a pump however...
for ease of instal with minimum headache i think you did a wonderful job however
Here is what came with my pump.
Read the sales pitch.
I run over 135 mph in the 1/4 and most of the time around 10.10 or 10.20.
I don't think you will be turning those numbers with your pump.
Yes I have to get on the brakes to keep it just below the 135 mark.
I am having my chassis certified tomorrow by Mike Rice ,
NHRA's annual visit to Maui .Then on friday I will see what the motor will realy do
Maybe the pump will screw up then
The Best of Corvette for Corvette Enthusiasts
you have to brake to keep from hitting over 135?
i hope and wish and dream i might see power like that
and stopping the damn thing at the end
I do see why you need a schute but about $500.00 bucks and all it does is slow you down
maybe thats not a bad thing after all
I hooked mine to the alt at the back to make sure the voltage is where it needs to be .I ran it off the intank wires on my last motor and had no problems .
