HELP - Where to mount fuel pump..?!

Advice & pics if possible:
Car: 1972 Duster, 408 Stroker, solid cam, six-pack (450+ hp)

Situation: I'm completely replacing/updating my fuel supply setup...ie: trashing stock 5/16" lines, Holley Black pump, dead-head Holley Reg to 5/16" lines to the six-pack. Pump is LOUD, mounted all wrong (above the tank & horizontal)... the entire system is chocked, and robbing power. This is how I bought this project.

Upgrade: Installing new Mallory Comp 140 pump, moving to 3/8" lines, 3/8" tank pickup, good fittings (no brass crap), Bypass Reg with a 3/8" return line, 3/8" to the carbs....plus a filter before the pump and an in-line filter between the Reg & the carbs. (this is a street car with sub 500 hp)

QUESTION: I know the pump must be mounted vertically, and BELOW the fuel source ala gravity feed to the pump...but I'll be danged if I can see a way or place to mount it without the rearend possibly contacting it or the exhaust cooking it AND the canister filter setup..... all very tight between that rear & tank face (stock tank). >>> H E L P !!!

I'm no rookie to the car dance we all enjoy... but have not had such a tight area to deal with before. Obviously loads of you guys have done this on a Duster... could you please share what you did, how you mounted the filter & pump and (if onhand) share pics...? Whatever you share would be GREATLY appreciated.

Reviewing numerous threads in FABO, and other muscle car sites, I decided the Mallory Comp 140 is the best fit for my needs. I queried FABO a number of days ago on replacement pump 'advice' (post is still here) and was bascially ignored, which surprised me :angry3:

Here's hoping I find some kindred spirits this time willing to help on this one, cuz folks I'm pretty stuck. :scratch:
