Hey, I was just wondering what else should be replaced while I put in a new pump?

Are the sending units prone to failure?

It is going to be the Walboro from Summit. Part Number GCA758-2.

Is this part all I need?

I take the pulsators out. The regulator may make a bit more clicking noise but no bigE.

 

Oh, it can be a bigE - see this post:

I have seen and posted in that thread. Very odd problem. It sounds to me like the new style injs are not isolated from the fuel rail or intake base and are hammering.

I couldn't hear my regulator if I tried because of the solid roller cam in my motor.
