For what you are doing, I wouldn’t do it. I don’t have the guts.
I wouldn’t even use a mechanical pump for that. I’d find a 140 gph (or bigger) electric pump and run a bypass regulator for what you are doing.
It’s a PITA because you have to run the return line (both the return and the fuel line should be #8 and #10 would work too) and you have to run a loss of oil pressure kill switch so if you get into a crash and the engine shuts off the pump stops with it. You don’t want to be in a crash and have the pump (especially a big pump like that) blowing fuel all over hot engine parts. You’d be getting toasty right quick.
