Ok, a check valve actually has crossed my mind, I would appreciate any updates on how difficult doing something like that would be

 

Regarding the regulator placement, referring to just what I have done in the past with an EFI set up. the regulator should be near the fuel rail, this will give you a constant pressure at the injectors, & will allow the pressure at the injectors to stay the same, no matter where you are in the throttle....

My plan would be to use a check valve at where the pump outlet exits the tank. Earls & Goodridge Performance hose companies make these, approx $40, w/ an approx. .2 psi pressure drop across the valve, if memory serve's me correctly........

Thanks for that info saves me some leg work.

 

OK,
just to keep the info flowing.....food for thought

This is from the FSM, for my 2001 Ram 2500
"Fuel pressure while engine running = 49.2 psi +/-5 psi"
"a properly functioning pump should pump 1/4 liter (8.5oz) in 7 seconds"

In a previous post, it was mentioned that the use of GM TPI pump might work, I have researched it, & either they meet the pressure requirement or the flow requirement, but not both together. let me know if I'm looking this up wrong......

Variable speed fuel pump ramps up with demand. I maybe wrong.
