Fuel Pumps NB8A NB8B

Postby Divo » Wed Apr 04, 2012 9:14 pm

Hi

Is there any difference between the fuel pumps in the 2 models? One uses a "returnless" system and the other doesn't. Wondering if the returnless version requires a more powerful pump?

cheers

Mark

Thought the NB8s all had a returnless system. NA8 was, of course, return type.

Aussie and Jap delivered NB8As have return systems (I have owned both these). I have read that US cars have returnless on their NB8As, but no first hand experience.

Was looking at a USDM fuel rail, so that explains it.
