You definitely DONT want a T fitting, you want a decent Y fitting that will flow halfway decent. The only one we use that anywhere near compact is a stainless steel Y about 1.5" long and 3/4" wide, much more compact than the yblocks you can get at Summit etc
And onthe hose reg fuel injection hose is not good enough for in tank use, you need SAE 30R10 rated submersible line, Ive done many dozens of fuel pumps in these cars and reg hi pressure FI hose (SAE30R9) is not holding up over time. That hose is expensive as hell, but you only need it to get it out of the tank

I need a short Y fitting, do you have the brand or link to where I can buy one?

Duals is not really that big of deal. over 550whp you need to start thinking about using dual walbros. Over 400whp on e85 needs duals. Now the hat trick triple walbros, that is when you are getting serious

Regardless I'm still curious about the motor.

Your not the first to make that mistake. I wish people wouldn't call it a 340 it confuses people. Besides the gss340 is still around but most GM applications have been moved to an updated f20000169 part number. Still 255lph rated which is the largest universal pump walbro makes.
