- Features
- Fits
The RFE-LB1 line pressure booster kit is an improved design over the 44957-LB1 & 2 kits and, comes with an integrated chip, (IC) circuit and a stronger pressure regulator spring. The improved design has three benefits over the 44957-LB1 & 2:
- A progressive pressure increase, (approx. 10 PSI) at lower pressure ranges and a greater increase, (approx. 25 PSI) at higher pressure range.
- Greater sensor voltage range compared to old design reduces potential for trouble codes.
- One kit can be used in both gas and diesel applications.
