Why dont we take a step back and start from square one. OP is your truck stock? What mods do you have if not? Stock lift pump can support plenty of power so unless you north of 6 or 700hp that's not likely your problem. Check the low pressure fuel with a gauge and see what it does. If it holds steady when rail doesnt meet commanded it's probably not the lift pump.

The code my truck is giving: P0087, I just ordered a fuel pressure gauge. I want to monitor the pressure. I heard that the in tank fuel lift pumps the Ram puts in stock are junk. Carter lift pumps don't last. I don't want to keep dropping my tank to change the pump. That is why I'm thinking of an Airdog or Fass. Tell me your thoughts. My truck is completely stock.

Dont know where you heard the stock pumps are junk from but they are not. How about what mods you have done to your truck?

Haven't really heard many folks say 4th gen Ram 6.7 lift pumps are "junk". Must be good ol' boys carrying on the "Dodge lift pumps are junk" from back in the 1st and 2nd gen days.

Until you get that fuel pressure gauge hooked up and report back the results, there is no sense in us all speculating Let's get the data and then make a recommendation on what to do

The lift pumps installed in the 91.5 trucks were the best in the 89-98 era of the 12v.
