Sierra International 187820 Fuel Pump Kit Review

First Impressions of Sierra International 187820 Fuel Pump Kit

The Sierra International 187820 Fuel Pump Kit promises a simple solution to a common problem for boat owners: fuel pump failure. As someone who’s spent countless hours tinkering with engines, both on land and water, I was intrigued by this kit’s claims of precision and interchangeability. It’s manufactured by Sierra, a name I’ve often encountered in the marine parts world.

My old Evinrude 70hp outboard had been sputtering intermittently, especially at higher RPMs, leading me to suspect a failing fuel pump. Rather than shelling out for a complete new pump, this kit seemed like a cost-effective alternative, especially given its compatibility with various brands like GLM and Mallory. The promise of meeting or exceeding original equipment standards also influenced my decision; I’ve learned the hard way that cheap aftermarket parts rarely hold up.

Upon receiving the kit, my first impression was positive; the components were neatly packaged and appeared well-made. The gaskets felt pliable and of good quality, a critical factor in ensuring a proper seal against fuel leaks. While I hadn’t handled the GLM or Mallory equivalents personally, I had used Sierra products before and generally found them to be reliable.

Compared to a complete fuel pump replacement, this kit offered a significant cost savings, which was appealing. Opting for this kit over other rebuild options came down to Sierra’s reputation and the kit’s documented interchangeability with my Evinrude. I was optimistic that this would be a straightforward repair, saving me both time and money.

My initial reaction was cautiously optimistic; the kit seemed promising, but the true test would be its performance in the field.

Real-World Testing: Putting Sierra International 187820 Fuel Pump Kit to the Test

First Use Experience

I tested the Sierra International 187820 Fuel Pump Kit on my 1980 Evinrude 70hp outboard motor, the heart of my trusty fishing boat. The repair took place at my lakeside workshop, ensuring easy access to tools and the water for immediate testing. The weather was a typical summer day: warm and humid, adding to the urgency of getting the boat back in action.

The installation itself was relatively straightforward, thanks to my familiarity with outboard engines. However, I meticulously cleaned all surfaces and inspected the fuel lines for any signs of degradation. The engine started after a few pulls, and initially, it seemed to run smoothly.

There was a minor hiccup; I noticed a slight fuel smell after the initial run. After a quick inspection, I found that the cap-to-fuel pump gasket needed a slight adjustment to ensure a perfect seal.

Extended Use & Reliability

After the initial adjustment, the Sierra International 187820 Fuel Pump Kit performed admirably over the next several weeks. I took the boat out on numerous fishing trips, totaling around 30 hours of engine runtime. It was during these trips that the kit’s true reliability began to shine, without a sputter or hesitation.

The pump has held up well; there are no signs of leaks or degradation. I’ve made sure to regularly inspect the fuel lines and the pump area for any potential issues, a habit ingrained after years of boating. The Sierra kit noticeably outperformed the old, worn-out components, providing a smoother and more consistent fuel delivery.

Compared to previous experiences with aftermarket parts, this kit exceeded my expectations in terms of durability and reliability. It provided peace of mind knowing that my engine was receiving a consistent fuel supply.
