I'm having a issue with my fuel pump as well. I think the EP241 is too tall for my tank that i pulled out of a chevy blazer. It was like a '01 blazer. The tank looks MUCH smaller then the one your using and I know if i use the wrong fuel pump (I.E. dont push enough PSI, even by a little) the truck wont start at all. I have considered maybe getting a Walhbro aftermarket high flow and putting it in the tank. I was needing to know the GPH and PSI and know i have it.. thank you sir

Awesome!  One thing, will the later model (87+) sending units "drop in" my older 84 tank?  Or I am I better off replacing the tank with a later model.  The tank is only about a year old, thats part of the reason I would like to keep it.
Yes the sending units will work with the non-87 EFI tanks.  Just don't run them completely empty as in keep about 3 gallons in it.  There are baffles in the EFI tank to keep the pump "submerged" if you don't run it dry, you will be fine.

My tank is from a 89 EFI Blazer and it is 31 gallons and was designed to fit in between the frame rails.  I am not sure what pump an 01 Tahoe calls for, but the factory one will supply enough fuel as they came with LS motors.  The EP241 will supply enough fuel for a LS, until you start getting boost crazy.

Thanks Cap!  Saving me some money to put towards a Yates harness.

Sunday, September 9th, 2012:Finished up the main ECM wiring Loom.  What is left is the Alternator, Starter, Fuel, Grounds and Power tie-ins.  The Power wires need new terminals added so they can connect to the factory distribution block.  I couldn't find the starter and MAF so I need to get them.

Saturday, September 22nd, 2012: After getting the starter I moved on to the Torque converter and found an issue.  I wasn't able to fix it immediately so fast forward and I ended up having to drop the trans and replace the flywheel that was bent in the center.  There way no way to bolt the torque converter up.

Sunday, September 23rd, 2012: With the trans out of the way I moved on to the wiring.  Got the grounds (can see them) connected and put new ends on the power terminals to connect it to the factory junction.  I also routed the starter wiring down to the starter along with the power cable to make sure I have enough room and then started looming the starter wiring.

Wednesday, October 10th, 2012: Got the starter and alternator wiring loomed with the rest of the wiring.  Spliced in the Painless wiring with the Alternator plug and swapped the ECM from Red 15 to Red 52.  ( This is NOT correct, I ended up putting this back in slot 15 to get it to charge..) I also removed the L terminal wire from the alternator plug.

Sunday, October 21st, 2012: Made a connector harness to extend the gas tank/pump wiring back to the Blazer tank, and got it loomed.  Added a ring terminal to the ground wire.  At this point in time I am done with the wiring except for the radio...

Sunday, October 28st, 2012: No pics, but I did get the battery hooked up in the truck and was actually able to turn it over.  Apparently my maniacal removal of wiring was a little overzealous.  I will have to add an actual wire to the Dakota controller that has actual constant power on it and I need to add ACC power instead or RUN power to it also.  I am fairly confident that it will crank though, just didn't have power to the VHX setup.  I also can't hear the fuel pump priming, so I need to track that down.  Nothing is in the tank, so that should be easy to find.  Short video of where I turned it over...
