Can someone please tell if there is any differences between a truck fuel assembly and a suv assembly? Does one provide more flow/ psi than the other? 03-06 Silverado vs 03-06 escalade for example

 

I compared a 2005 6.0 Escalade to a 2005 Silverado 5.3/6.0 pump and the top hats on the pump assembly are different for the fuel feed and evap lines.

Both were AC delco pumps and being that GM didn't change fuel pressure ratings since 99 they should both be rated at 58psi under load.

 

I believe the buckets are different in heights as well.

 

Which one is bigger?
