?? eh ?? lots of Maxima owners have swapped out the stock pump for a Walbro, and I don't remember hearing about "modifying it"... I didn't.

Look here for pix on a fuel pump swap-out

need a fuel pressure regulator to bring the pressure back down....

not familiar with your car so I dont know your options..

 

Yup - sounds like you need a good regulator - I use this one, the xxx-105, set to 43 psi. Works OK on the 3.5, anyway...

You'll need two -6AN/hose adapters to hook it up. Look around in Jegs.

 

ok its says that the 6an fittings are included? do i need two more or am i reading iit wrong? thanks

 

It comes with two screw-in fittings that are the -6AN male connections - you can see them in the photo - but you need two more connectors that screw onto the male connectors.

Like these: http://www.jegs.com/p/JEGS/JEGS-AN-P...73391/10002/-1

just push the fuel hose onto the ribbed end and clamp it.

 

o ok cool thanks
