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: 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! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07MKBX7HT | | Auto Part Position | Rear | | Best Sellers Rank | #2,696,142 in Automotive ( See Top 100 in Automotive ) #19,150 in Automotive Replacement Electric Fuel Pumps | | Body Material | Plastic | | Brand Name | Tuzliufi | | Compatible with Vehicle Type | compatible with | | Customer Reviews | 3.9 3.9 out of 5 stars (40) | | Fit Type | Universal Fit | | Gas Type | Gasoline | | Inlet Connection Type | Hose Barb | | Manufacturer | Tuzliufi | | Manufacturer Part Number | Z204 | | Manufacturer Warranty Description | 1 YEAR | | Material Type | Plastic | | Model Number | Z204 | | Mounting Type | Flange Mount | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | Compatible with 3H6-04000-3 3H6-04000-7 3H6-04000 3H6-04000-1, Compatible with 504977 ., Compatible with 803529T 803529T06 803529T01 803529T02 803529T03 803529T04 803529T05 803529T07 | | Operation Mode | Mechanical | | Outlet Connection Type | Barb | | Product Style | Mechanical | | Specification Met | OE | | UPC | 755101190012 | ## Product Details - **Brand:** Tuzliufi - **Fit Type:** Universal Fit - **Material:** Plastic - **Style:** Mechanical - **Vehicle Service Type:** compatible with ## Images ![Fuel Pump for Mercury Mariner BRP Tohatsu 3H6-04000-3 3H6-04000-7 803529T06 504977 MFS4A2 MFS4B MFS5A2 MFS5B MFS6A2 MFS6B MFS8A MFS8A2 MFS8A3 MFS9.8A MFS9.8A2 MFS9.8A3 Z204 - Image 1](https://m.media-amazon.com/images/I/51Fs4cRoS8L.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/109158847-fuel-pump-for-mercury-mariner-brp-tohatsu-3h6-04000-3](https://www.desertcart.jp/products/109158847-fuel-pump-for-mercury-mariner-brp-tohatsu-3h6-04000-3) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-01*
