## Description

Full description not available

## Features

- We have 2 similar pumps: Z204, Asin: B07MKBX7HT; Z533, Asin: B08DTGFMT7. The difference is mounting holes. This is Z204. The mounting holes are round and smaller than Z533.
- No bolts included. In most of packages(not all), coming with 1 gasket(O ring). You may need to use your own o-ring when install it(Only in some new inventory , O-ring is included). Compare the diameters of the flange that inserts into the hole in the crankcase. Compare the diameters and distance between the 2 mounting holes before placing order. We mark size in pictures.
- Someone (less than 5% ) said the distance between the centers of the holes was slightly greater/smaller than the mounting holes on his outboard engine. One ear cracked on fastening. What I see is that the pump has to be pushed in by hand, first. If you try to use the screws to torque the pump into place, it is likely that the plastic ears will break;
- Someone complain about the bolt holes not lining up.We desire BIGGER round holes to fix the issue. You could check Z533 in our store: https://www.desertcart.com/dp/B08DTGFMT7 ; We mark size in pictures. Compare size （Especially the distance of mounting holes）with your original pump carefully before placing order. If it is smaller/bigger than your original one, you could try Z533, Asin: B08DTGFMT7.
- Note: This item is a replacement part. Not OEM part. Please make sure the images are the same with what you want. If not, please do not purchase it even your model is in the described list!

### ⭐⭐⭐⭐⭐ Worked well
*by K***. on August 18, 2020*

Fit perfect, works perfect, and quality is good, so I expect no further issues with fuel.

### ⭐⭐⭐⭐⭐ Mercury fuel pump
*by R***S on October 31, 2019*

It arrived in a couple days, fit perfectly, and it worked.

### ⭐⭐⭐⭐ Good pump but has bolt hole differences on my Tohatsu.
*by W***N on February 24, 2021*

Great pump however, the 2 bolt holes may not match your engine block. You may damage the block by cross treading.
