In my case, finding a 15psi regulator is expensive, I bet there are cheaper ones- http://www.summitracing.com/parts/aei-13204/overview/

But for you MPI guys the regulators are cheap........30-70psi adjustable.

 

 

The question is- Why not bypass the existing in-tank fuel pump and run an external with regulator and never worry about it again?

Seems like it would work. Only reason I can think of would be retaining stock setup. Also, the internal pumps are mostly cooled by being immersed in fuel, which you wouldn't be able to do anymore, but any external setup worth its salt would have provisions for that. I am wondering why you'd need to go with such a high pressure pump if all you need is 15psi, but I suppose that's a cost thing?

I run an external pump with a fuel cell in my 87 weekend toy. Feeds into the stock fuel rail with the stock regulator and return dumping back into the fuel cell. Even drilled an extra hole for a breather (with a roll over valve) plumbed into the evap canister.
