## Description

New LOW pressure fuel pump for many Mercury Mercruiser engines. This is a low pressure pump with threaded outlet.

Review: Low pressure was high pressure...NG - I bought this as a low pressure pump to replace a failing pump. Bought it in October 2020, but didn't run it until May 2021. It was threaded on both ends like a low pressure pump. Ran the boat, it started flooding out. Was pumping too much fuel into the carb. Way too much. Borrowed a gas pressure gauge, it was 20PSI, blowing right through the carb. Low pressure pump is supposed to be 5-8PSI Not a suitable replacement, be careful.
Review: Junk!! - This is how I received the fuel pump! Strike 1!! So I over looked that and decided to install it on my mercruiser engine. Should have know the POS doesn't work!! Strike 2!! So I removed the pump again and bench teted it with a power probe kit. As I'm load testing this pump sparks were arking across the bench! Strike 3!! And yes I had the ground wire grounded!! Well designed pump for a fuel system!! Don't buy this product it could have turned out in disaster!!
