My personal experiences with Mopar in tank pump assemblies in Jeeps is they are very long lived compared to most other high pressure in tank pumps in the industry, which are short lived. Back to the GMC carb vs EFI debate-- if the reason for doing it is vapor lock, that can be corrected by installing an external feed through low pressure pump near the Aux tank and opperated via the existing Aux seitch via a relay with total parts costs well under $100. I have found all the wrapping and insulating a futile exercise. VL occurs before the mech pump in my opinion. Flip the switch and it's fixed every time. Also a well set up Qjet will start smoothly, transition cold to warm seamlessly and be very dependable. The only reason I would go to EFI is if I lived or drove a lot at altitude. It can't add air density but can pull fuel automatically at altitude keeping the engine more in the correct range to make the most of the thin air
