Default l83 pwm fuel pump height

I'm doing a full custom c10/genV and starting from scratch.
I've decided on using the pwm fuel system and trying to find the best stock module for a tank that is 10" deep. After looking at some modules it looks like 2018 & later have the pressure sensor as part of the module, is that right? Are all modules compatible with a 2016 l83? not planning on modding the motor other than afm delete cam so I'm looking at some stock 5.3 modules. Are the pumps adjustable in height (springs in pics)? Suggestions/opinions appreciated thanks!

I used the Silverado pump in a 12" deep tank, it's adjustable but very hard to get at so I'm sorry I don't have the height. I'll see if I have it anywhere.

Cool, thanks. I ordered a silverado unit today that shows an inch or so longer than my tank is deep, hopefully it will sqeeze down and fit.
Just out of curiosity, how happy are you with the swap (I assume it is running)? I was holding out for an l86 on this project but a low mileage l83/6l80 came up locally for peanuts and had all of the misc. stuff with it so I just went for it.
I'm sure I will be a regular on here until I get all this crap shook out...

I'm close but not done yet, I did a frame up restoration on a Land Rover Defender, been at it for a couple years. When I was talking to Mitch at Swaptime he said it's comparable to an LS3. I had an LC9 5.3 in my Jeep and I was never looking for more power so I think this will be great.
