There was no fuel pump wiring upgrade "kit" when I did my combo.
It was [one] of the reasons why I did a BAP because I was considering running new wire anyway so... WTH
Not to mention that I was burning up the phone lines to Kenne Bell back then with questions. More than one person that I had spoken to, recommended the BAP for the same reasons I recommend it. The thing is rock solid. Headlights, A/C, Defrost; I can turn it all on at the same time and the pump stays steady. I have a similar device that keeps my coil saturated/steady with dials in the cockpit that I have set and forgotten (no need to adjust once set).
