Reviews
What buyers praise and complain about, mined from review topics.What buyers love
“strong pump”
“and it looks like a great quality pump”
“It fits my sending unit”
“As advertised”
“Price is good”
“it got me 50 miles to its new home the build quality is decent would be nice if it had more labeling I had to play with it to figure out the direction of flow the fuel pressure is really decent almost too much as I needed to redirect my return line it was flying through fuel all in all GREAT value option if you dont wanna spend the 100+ dollars for a factory fuel pump also this is easier than dropping the fuel tank”
“Worked”
“it was very easy to install in the Miata's gas tank”
“This pump is extremely quiet for a high flow pump which was nice”
“still running strong”

“working on it suddenly nothing”
“Waste of money”
“Showed up with no filter for the pump”
“Fuel just bleeds by without it being on”
