Re: 37 with efi… yes please

my EFI tank came for my Dart last week and in the box was the universal sending unit. it is Ohmed for Mopar. 75-10ohm. but that just means i need a gauge for that setup. no worries there. I will get an aftermarket gauge.
I tested my original sending unit and it was fine...so either my "runtz" blew or the gauge is dead because i left the key on and it got too much voltage too long. either way....it wasn't accurate anyways. so i'll mount a new one under the dash.
if anyone was wondering....the newer senders will fit the top of the tank. same bolt pattern. i just drilled a hole in it and made my own pickup tube. i would have made my own return line, but not enough room and honestly...it BARELY fits back in the tank as it is in the pic. but it works.
also....getting that return line fitting on and tight was a PITA!!! damn fat, grown man hands!!!
i temporarily setup the wiring for the efi so i could test it and well....we have our first 1937 Packard 120 282 running EFI.
the car has NEVER ran this well....EVER....again.....EVER and the coolant temps were much much better. probably because its running at the right A/F level now. I was also better able to adjust idle rpm and several other parameters.
obviously it is not setup fully and it has learning to do...but it runs and runs VERY VERY well.
the intake adaptor i made...was cold to the touch...and i mean literally cold. there was sweat on the aluminum riser. vapor lock will NOT be an issue now. and just from it running in the garage...i can tell its making better power too. can't wait to drive it.
here is a video of it running. me blipping the throttle like that was to show it does not bog like the carb did. it literally just goes. the clicking noise you hear is not the lifters...its the injectors in the fuel rail. you can't hear it when the breather is on, nor in the driver's seat.https://youtu.be/9a4EdrH1Crg
