The small outlet end is threaded for low pressure applications only - This is a low pressure pump that fits carburated engines with a single fuel pump or some fuel injected engines that use a low pressure and a high pressure pump system. This is the low pressure pump that is threaded on the small outlet end. The high pressure pump looks similar but is not threaded on the small outlet end. The high pressure pump is enclosed in the 'cool fuel' assembly and this will not fit work in that asembly. Low pressure pumps are not in any assembly. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N05B88N | | Auto Part Position | Front | | Automotive Fit Type | Vehicle Specific Fit | | Body Material | Metal | | Brand | Low Pressure | | Brand Name | Low Pressure | | Compatible with Vehicle Type | Car | | Connector Type | Threaded | | Fit Type | Vehicle Specific Fit | | Fit type | Vehicle Specific Fit | | Gas Type | Petrol | | Global Trade Identification Number | 00701649133790 | | Inlet Connection Type | Threaded | | Item Dimensions | 27.9 x 7.3 x 7 centimetres | | Item Weight | 23 Ounces | | Item dimensions L x W x H | 27.9 x 7.3 x 7 centimetres | | Item weight | 23 Ounces | | Manufacturer | Marine Fuel Pumps | | Manufacturer Part Number | 100595_A3 | | Material | Metal | | Material Type | Metal | | Mounting Type | Threaded | | OEM Equivalent Part Number | 861155A3 | | Operation Mode | Electric | | Outlet Connection Type | Threaded | | Part Interchange Info | replaces part | | Product Grade | New | | Product Style | Modern | | Specification Met | OE | | UPC | 701649133790 | | Unit Count | 1.0 count | | Vehicle service type | Car | ## Product Details - **Auto part position:** Front - **Brand:** Low Pressure - **Fit type:** Vehicle Specific Fit - **Item dimensions L x W x H:** 27.9 x 7.3 x 7 centimetres - **Item weight:** 23 Ounces - **Material:** Metal - **Outlet connection type:** Threaded - **Specification met:** OE - **Style:** Modern - **Vehicle service type:** Car ## Images ![Low pressure electric fuel pump for Mercury Mercruiser 4.3, 5.0, 5.7 carburated engines, replaces 861155a3 - Image 1](https://m.media-amazon.com/images/I/61K0PB9NIEL.jpg) ![Low pressure electric fuel pump for Mercury Mercruiser 4.3, 5.0, 5.7 carburated engines, replaces 861155a3 - Image 2](https://m.media-amazon.com/images/I/51NmjU2VPmL.jpg) ![Low pressure electric fuel pump for Mercury Mercruiser 4.3, 5.0, 5.7 carburated engines, replaces 861155a3 - Image 3](https://m.media-amazon.com/images/I/61dqEx5FHPL.jpg) ![Low pressure electric fuel pump for Mercury Mercruiser 4.3, 5.0, 5.7 carburated engines, replaces 861155a3 - Image 4](https://m.media-amazon.com/images/I/51mQYAzcI9L.jpg) ![Low pressure electric fuel pump for Mercury Mercruiser 4.3, 5.0, 5.7 carburated engines, replaces 861155a3 - Image 5](https://m.media-amazon.com/images/I/51nuRXqLAML.jpg) ## Frequently Bought Together - Low pressure electric fuel pump for Mercury Mercruiser 4.3, 5.0, 5.7 carburated engines, replaces 861155a3 - Quicksilver 802893Q01 Water Separating Fuel Filter for Mercury and Mariner Outboards and MerCruiser Stern Drive and Inboard Engines - 10 Feet Long Fuel Line Fuel Hose Fuel Tube 1/4" ID x 3/8" OD with Hose Clamps for small engines --- ## 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.tn/products/105436856-low-pressure-electric-fuel-pump-for-mercury-mercruiser-4-3](https://www.desertcart.tn/products/105436856-low-pressure-electric-fuel-pump-for-mercury-mercruiser-4-3) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-01*
