preferred brand of intank fuel pump 88 TBI 454

I need to order two new fuel pumps and sending units for my project truck(1988 gmc r3500 454 wTBI). What is everyone's preferred brand? I have twin tanks as well. Thank you in advance for any help on this.

I’ve always ordered GM or DELPHI from rockauto.

I also will only use AC Delco or Delphi - I have replaced too many Carter pumps and I only like to do that job once!

I always use the ep381 pump (96-up vortec) on my tbi trucks, have been since they came out, and have never had an issue. Some recommend the ep377 (94-95 454 tbi) but I would NOT use an ep386, which is what came in the truck. They barely supply enough fuel for a 350, much less a 454.

Delphi. Avoid GM pumps. Anything new is made in Mexico w/these. I installed both L/R new units on my dually (circa 2015) & both failed within months (<6). Swapped to Delphi's & no issues.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
