[QUOTE="po-po 5.0, post: 15558991, member: 44534"] The little blue plug you see in the pics can be removed to plumb a return line. All fore hats are built that way. Will you NEED a second FPDM? Maybe...maybe not. There seems to be several answers to this question depending on who you ask: 1. No, you're fine, but under extreme conditions you might overheat the stocker 2. No, you're fine, but you need to upgrade the power feed to the stocker to prevent overheating 3. No, but you need a modified FPDM (do they even still sell these?) 4. No, but you should probably get a BAP when you get to boost 5. Yes, get a dual FPDM kit. Me personally, I want with the dual kit as I use my car on a road course which means that I'll be asking the world of the FPDMs for a lot longer periods of time than your average drag racer or light-to-light kind of guy. It's up to you who you believe. Fore hats necessarily delete the PPRV (positive pressure retention valve). This means that no pressure is retained in the fuel system when you turn off the key. Normally, this means nothing on a cold start as the pumps run full-out when you hit the key, but they DON'T on a hot start. So you'll have to leave the key in the on position momentarily to allow the pumps to re-prime the system or you'll get a very long crank time. You get used to it real quick. [/QUOTE]
