So I have a few questions regarding my fuel system. I'm going to start planning out how I'm going to upgrade. It's a 98 with return type system and i currently have 2 190lph pumps with a BAP. I've been looking at Glenn's system but 1500$ seems like a lot of money. My other idea is to buy 2 255lph walbros and upgrade my rails and lines and remove the BAP. my question is do I have to add another FPDM? Or a modified one? Or does it not matter since its return system

 

Oh and I'm looking at around 650 wrhp range. Injectors I'm planning on going with 60#
