MFI to webers fuel pump location???

i know that there are numerous threads regarding converting from MFI to carbs, but i am uncertain as to which location is deemed the best for the fuel pump. i would rather mount in the rear location on my 72T but note that some prefer the front. would welcome any advice or experience with the rear location!!!!

Pushing fluid is always easier than pulling. Ideally, you would want the pump as close to the gas tank as possible.

I'm running a Facet in the engine compartment.

It's mounted on my '71 with a 2,5 and Webers. No regulator.
Yea, I know now, it's not supposed to suck, but it does fine mounted like this. I installed this in 1983 more than TWENTY-FIVE years ago and it has run flawlessly ever since. That includes regular autocrosses and DEs.

I just kept the MFI fuel pump and filter console. I just tap into the "loop" that used to go to the belt driven injector pump with a regulator. Very simple set-up and easy to do. Just put a "T" fitting in the line that used to go to and from the belt driven pump. Attach a low pressure regulator to the T fitting and plumb the outlet from the regulator to the carbs. I used a low pressure Holley regulator that has one input and two outputs.
