Proper Mixture.

[Gary W Harris]

Text item: 

The best solution here is to get a complete gas tank assembly from a 
later model year vehicle that was OEM equipped with the in-tank pump.  
This tank will have the proper baffleing to prevent fuel starvation.  
the fuel return on these tanks also routs the fuel back to the baffled 
area, which helps maintain a constant fuel supply to the pump.  Mike 
Knell's remote tank is a good solution if you can't get a "modern" fuel 
tank!  Mike has a web page--http://www.jagsthatrun.com

I would not worry about what the ECM is doing.....  What about running the
pump dry?
The ECM won't change dramatically in a couple seconds, and if you are on/off
the throttle, probably won't change at all.

I would think that running the pump dry might shorten it's life.  The Mike
Knell book on Chevrolet TPI and TBI Engine Swapping had a neat idea to stop
engine from dying in this situation.  He made a little reservoir box to hold
fuel that fed the high pressure pump.  A low pressure pump fed the box from
the tank.  Requires two fuel pumps, but solves the problem if you can't get a
baffled fuel tank.
