Fuel pump mounting advice

Hi all, Been a while since I looked at this, thanks for the responses.

As for my project: I purchased a new Mallory Comp 140 off Ebay ($150). I'm also upgrading/replacing all fuel lines to 3/8". The thing I've really been stuck on is the continual chant of; "must be mounted vertically, at or below the fuel source". For a Duster, that's a tough pill, because the stock tank already sits low (not sumped), and is very close to the rear-end. I was thinking of squeezing it between the tank & the rear, up against the tank on the left front, and it would have been ok with about 2" to spare ...as long as it didn't move... but damn tight! In this location, the pump inlet/outlet would be level with the bottom of the tank, thus easily getting proper feed.

Having said that; I've decided to attach a mount-plate on the left frame behind the wheel well, basically beside the forwadr front of the tank-side. This affords plenty of room, proepr gravity feed, and no fire danger. Due to this decision, I am now committed to running very short muffle pipes that will end just after they loop over the axles.

I'll attach before and after pic's once it's all together.
Thx all ~
