I tried to run both pumps together with my set up on the stock feed, and even with the drilled siphon, I was getting 60 psi at the fuel rail, so i just added a hobbs switch set to 9 psi.

i'd hate to assume, but i would think an aftermarket regulator would have solved that issue. i guess that doesnt matter though, you solved it without spending a couple hundred bucks on a part that you didnt need in the end.

I think I'm about ready to do a complete AN fuel system and stop dinking around.

I come from the Old World of TurboBuick GN's. Almost two decades ago, a Buick aftermarket supplier called Applied Technologies & Research(ATR) designed a double pumper fuel pump with dual WALBROS and they did it right with a machined, billet aluminum "Y" connector joining the two pumps.

I had one of these on my Buick and it was a really nice piece of kit. It was so much nicer than the current Evo double pumpers available which use two pieces of rubber hose instead of a machined, billet "Y" connector.

Maybe the Evo suppliers should take a retro-look at the groundbreaking, original 1990's ATR Double Pumper with a Billet "Y". I realize that I am talking about the previous century's technology. But, really wow two pumps connected by two chunks of flexible, rubber garden hose cut with a BoyScout knife, Duh?
