I've been benefitting a ton from the various Sniper content here...and all the other content too. Thanks all! I figured I'd share some details of my setup in case it helps others in the future.
Fuel Tank:
I started the project here with the plan to install the pump in the tank. My tank did not have the flat spot where the hold is drilled and the pump is installed. (see photo) Really strange. Pulling the tank wasn't to hard, just slow with all the stubborn hoses. The tank has been reinstalled now with new gaskets and some new hoses...most of the hoses looked good. (I have a Mosely Motors in tank fuel pump kit that's untouched if anyone wants to make me an offer. )
Fuel Pump:
It would be so much better if this was in the tank, but since that's not an option I installed the pump on the frame rail. I designed and 3D printed some brackets out of ABS plastic for the pump and the post fuel filter. These mount to the frame with a few drilled and tapped M6 holes. The steel is pretty thick under there! I used what Holley recommends for the filters: NAPA P/N 3033 for the pre filter and a NAPA P/N 3482 for the post. For the pump, it's a Walbro GSL394BX. I just ran the pump yesterday and...it's not quiet. There was no pressure in the line so hopefully it's a little more quiet when everything is installed. I don't think there's anything I could do outside of a surge tank under the hood, but I didn't want to go that route.
Fuel Line:
I wanted to used as much of the factory hard fuel lines so I just cut out a section of the feed line that runs under the truck. The factory line is bent away from the fuel rail in two sections and that's where I cut. This line is 8mm which fits a 5/16" hose perfect. The problem is that most fuel hardware seems to be 3/8" as are my filters and pump. I drilled out and soldered on 3/8" barbs onto the factory lines so that everything in that section is 3/8". Next up I'm going to plumb the hard lines to Sniper with 5/16" hose.
Header:
I had a JT Outfitters header ceramic coated black and used a Remflex gasket along with a stud kit. On my first install the tolerances on the headers were too loose and the washers didn't fully catch the headers. I tried centering it perfectly but still had the issue. Frustrating. I drew up some custom washers with a tab so they would fully catch the header flange. I had these laser cut online and it only cost like $40. I got ordered 1/4" thick just for overkill.
Desmog:
The car is registered in Montana and that's the only reason I can do all this. I also removed all the smog gear under the hood. Got rid of about a mile of vacuum hose. I think I got most of those parts from TLC including the air pump idler pulley. I removed it all carefully so it can be reinstalled if I ever feel to need do a showroom rebuild.
Up Next:
I need to finish the fuel lines under the hood, route the throttle cable, wire in the Sniper, fab the exhaust from the header to the cat, and setup the few vacuum lines that still need to be there including the HAC (I'm at 5k feet). Then it's on to tuning the Sniper. I'll send photos once I get there!
