Need help on my fuel for my 91 silverado. Its has 5.3 with tbss. And its getting returnless fuel rails. So would be better to run the inline walbro with vette fliter or in tank?

What are you going to use for a fuel pressure regulator?

I would run the walbro intank and add an external FPR with a return

May sound like a silly question but anyone have pics or diagram? Without a second port on the rails the return must be of the regulator only?

Who make the adapters to convert factory connector to an for the line?
Are you using the factory feed line for return?
What size feed line are you running?

If you set on using the stock returnless rails, do the intank, stock feed lines, summit has the adaptor for the fuel line to an, I'll get the part number when I'm not on my phone, to the regulator, from the regulator to the rails, and from the return on the regulator back to the tank.

Oh kook. That's guys...I have the fitting with fuel rail fitting already written down. I know ones a 3/8 s not sure bout the other one. On summit they sale 5/16 an 1/4 inch one. I will be running the tbss fuel rails. But the reason I asked inlined or in tank cause I'm working 91 silverado efi swap 5.3. I wasn't to sure which Be best, and I didn't know if they made intank walbro that fit in obs tank or not.

For a regulator I was going to use the Corvette fliter for ntill I'm ready for the fuel cell that I was thing bout doing

That would work. It will regulate it to a constant 58 psi.
