several pages and 140+ posts later the fact that this is a transplanted setup and unknown parts/pieces has escaped some of us, me included, let me give you a 'what I would do' answer.Here's the tank
Find a way to install a submersible fuel pump that's 155LPH, you can adapt the tank you have or get a tank that can accept a submersible fuel pump, wire it with an inertia switch like our fox cars have.
The reason for the submersible pumps are legit, higher pressure and heat go together, sub-pumps run longer and cooler,
I guarantee unless you spend big money on a external fuel pump like what's used on pro stock and top fuel dragsters those little inline external pumps will fail within 20k miles street use. Probably less.
The factory in tank pumps last 100k+ miles street driving.
I really need to post a disclaimer in my sig.
Disclaimer: 'what I would do' answers are prolly not based on any real mechanical experience, do not attempt without fire suppression equipment nearby.
