OK, the Division X return style fuel hat (Pictured above) arrived yesterday. I must say its a solid (Billet) piece and feels quite sturdy. Also in my box-O-Goodies was twin fuel pumps (Walbro GSS342's that can pump 255 Lph each) and the harness to ensure it all plays nice with the Saleens OEM ECU. Now, the Fuel hat has a -10AN outlet and a -8AN inlet. At the end of each of these 90 degree fittings are Male threads with a Flare (37 degrees). I had to separately purchase the fittings with the 3/8" hose barb to run my fuel hoses. -8AN fitting (female with flare- to 3/8" hose barb) was easy and picked it up on Jegs. However, NO ONE sells a -10 AN fitting (Female with flare- to 3/8 in hose barb). Finally after about 2 hours of trying my luck at multiple places, I decided to purchase a reducer to go from -10 AN to Male -8AN with flare. Then purchased a second -8AN fitting (female with flare- to 3/8" hose barb). I wasn't sure what this was going to screw up, so I made a call to a tech at Jegs. He seemed knowledgeable (at least more knowledgeable that I am in this ) and we "Chatted" a bit. I explained to him that I want to run 3/8" fuel hose through out the whole system (to and from the EFI). I asked him if there would be any negative effect since I am running the -10AN outlet through -8AN (I was assuming they made the outlet -10 AN for a reason. He explained (and anyone here can jump in if this is incorrect) that there is a large difference in LPH between 3/8 hose (which he said is about -6AN?) and the -10 AN (which he said is about 5/8"?) however, this difference would only become a problem if I were running super high horsepower (like over 1,000 HP) and said for my purposes, it should be fine.
I also picked up a FAST in line fuel filter. So now, the progression will be from the New Division X fuel hat, I will run 3/8" hose from the -8AN barb to a -6AN fitting(with 3/8" Barb) the -6AN fitting screws into the FAST inline fuel filter and another -6AN fitting with 3/8" barb off of that. From that barb run the 3/8" hose to the 8AN fitting with 3/8" bard on the first throttle body. The throttle bodies came with their own hoses and fittings to link them together. Then I run 3/8" hose from the 2nd throttle body barb to the FAST Fuel pressure regulator. Out the bottom of the fuel pressure regulator, run 3/8" hose all the way back through the same channel (Saleen has this channel down the drivers side where the fuel lines run and there is a flat plastic cover to keep everything covered...... really convenient) back to the inlet 3/8" bard on the fuel hat. Now the car has a Canister Purge valve up front in the engine bay on the driver side wheel well. I believe this runs to a separate location on the fuel tank (Saleen has a saddle style fuel tank). I will have to leave this in place and reconnect the harness plug since it allows you to fill up the gas tanks all the way to full. Without it, I was told there would be a headache of problems associated with filling up the car with gas. Also the FAST EFI system says that the fuel tank must be vented, and I believe this is the vent.
As you can tell, I am stalling on the headers because the thought is daunting, but once the fuel system is in place, there is nothing left (aside from troubleshooting during first start up).... So eventually I am going to have to do the headers. Wish I had handy neighbors who were into cars/welding. LOL
