[DML] Fuel issues



OK, I've had a few issues with my fuel system. It all started at a 
mall parking lot.

1. Replaced the boot as the old had disentragated into the tank.
2. Replaced the boot cap, as there was none.
3. Replaced the fuel line coming off the top of the pump, as it too 
was corroded, and broke when disconnecting it from the pump.
4. Replaced the filter in the baffle
5. Replaced the baffle with the John Hervey setup - Heard some good 
stuff from some of the guys at AZ-D who are running it, (seems to do 
the trick) - Since I replaced the entire baffle, there is no need to 
replace the hose that connects to the baffle
6. Replaced the fuel pump

Ran the car - Found that crud clogged up the new filter on the bottom 
of the pump.

Cleaned it out, cyphoned the tank (so that there was only about 1/3 of 
an inch of gas left in there. Wiped it all out (removing silicon stuff 
that someone had used to put back together the fuel sending unit, a 
random screw, and general crud on the bottom of the tank.))

Raised the fuel pump 1/4th of an inch to guarantee that the filter was 
not resting on the bottom of the baffle/tank

Filtered out the gas prior to putting it back into the tank. Ensured 
that all the crud (oil like goo with black lumps which used to be the 
boot for the gas pump) which had gathered on the bottom of the 5 
gallon buckets did not go back into the tank.

Put all back in, shone a flash light into the tank. Ensured nothing 
was floating around. Put the fuel sending unit back on/in

Replaced an in-line fuel filter just above the pump (not sure why one 
is there, but put a new on in anyhow)

Ran the car - worked like a champ... Ran her around roundabouts, on 
the freeway, and it did great. Parked the car, happy as a clam. Went 
to go meet my wife for dinner, and put new high octane gas into the 
car. Filled the tank up about 100% of the way. The car all-but died. 
Nothing I coudl do to keep the RPMs up. The car could be floored in 
Neutral, and I could barely get above 2800. Running in a gear was a 
joke. First gear running at 5mph, was about the fastest that I could 
go.

Turned off the car, started her back up --> could rev her up, but then 
same thing again when I had to turn a corner.

Got back to my garage, Left it running, ensured that there was nothgin 
squirting out when it was in neutral running. Found nothing. But what 
I did see was that the return line hole coming up from the boot, had 
allowed fuel to leak in and around the pump. Cleaned it out. Let the 
car cool (7pm). 

Ran it again at 10pm (it was about 50 degrees outside) the car ran 
great when cold, but the second it warmed up to standard operating 
temperature, same thing. No power. No RPMs. Turn off the car, you can 
get it (the rpms) up there for a few seconds to pick up speed, but 
then that is it. I would almost venture to guess that it is flooded, 
but since there is no carb, that would probably not be the case. 

Starts up good every time. Shone a light back into the tank, and the 
filter at the bottom of the pump seems to be clear and green.

Checked the connection at the bottom of the  inertia switch, it was 
not really hot, and appeared to be in good shape.

I could see from the car running (looking into the tank), that fuel 
was being sent back into the tank just could not see how much or how 
fast, not that I know how much or fast it is supposed to be.

When this is happening, the pump is quiet, ie not screaming. 

Help!
