in tank fuel pump for 5.3 swap

Need a little help with this guys. I'm wanting to keep things simple as possible after my car is built. I'd really like to go with an in tank fuel pump that fits directly into my stock sender/pick up. Does anyone know of such a pump?

My Walbro 255 was basically a direct swap. Everything needed was included.

I also have a Walbro 255 in mine. I just called summit and they got me one that was a direct swap. Been running it for 2 years now with no issues.

If you have a mild 5.3 then get a 96-00 vortec truck pump. Direct fit, 60psi, 7 yr warranty, under $100

It's a walbro 190
