I'm on my original VP44 and it shows no signs of weakness. No codes and supplied with plenty of fuel pressure (16 at idle - 13.5 WOT) Also burning 2 stroke oil 1oz/gal of fuel. I want to add the XZT+ but don't want to be foolish and add the box when the prudent thing to do is replace the VP44.

Thoughts from anyone who has already made this decision?

 

Take the XZT+ out of the equation. Now, why would you replace something that is working fine and showing no signs of stranding you?
I understand you are being cautious but it seems to me you'd be plenty safe with the XZT+.

Remember the old saying, "if it ain't broke......"

 

if its not broke y fix it? get the box some vps never seem to go out some will go out really quick, cant really control that if its not causing any problems i wouldnt worry about it.

 

I wouldn't replace a working VP, unless it was with a P-Pump
