Re: Winging a 1971 K5 Blazer L96 6L90 Swap
I used the Tanks Inc PA-4 unit. The pump will flow 255 liters per hour and handle up to 630 HP with 60 psi of fuel pressure. I'm running a stock L96 motor that produces roughly 360 HP, but eliminated the mechanical fan, added a cold air intake and plan to run stainless headers with 3" exhaust. I'm guessing the little performance upgrades will add maybe 40 additional hp. The reason I went with the larger fuel pump is that I wanted to keep the option of running e85 if I wanted and e85 requires 25-35% more fuel.
Yes, I did end up extending the reach of the fuel pump arm roughly 3/4" and extended the pick/return lines, so the unit sat flat on the bottom of the tank. I also wanted to change the line to make sure I didn't have issues if I ran e85.
I'm not sure on the clearance at this point, but figured I could drop the tank down slightly if there are any issues.
Thanks for checking out my build and I'll keep you posted when I start to fit the body.
