Carrier transcold pump is the way to go, picked it up from Genlightning, installed it, primes right up after fuel system servicing, adds the protection of an additional screen and filter bowl. Plus no more dealing with low quality garbage mechanical pumps that fail constantly. Heres a pic of it installed

If you search you can find the writeup I did for installing it, pretty simple.
If you run the WVO/WMO be aware that the transicold pump doesn't like them. It works great for diesel, but I am contmeplating putting the factory lift pump back in and using the carrier for priming because it won't pump the thick stuff at all.
