🔧 Key Features:
-
OEM Replacement – Trusted by Indmar for on-engine EFI fuel systems
-
EFI-Ready – Delivers the high fuel pressure required for fuel-injected engines

🔁 Important Service Note:
If you're troubleshooting fuel delivery issues, it's highly recommended to also inspect or replace the fuel pressure regulator (Indmar P/N 636126).
-
The pump delivers fuel, but the regulator maintains precise pressure (58 psi / 4.0 bar).

A failing regulator can cause similar symptoms: hard starts, hesitation, or poor performance.
