Not for fuel system. Your car is fuel injectected and fuel system is operaiting under much higher pressure then this pump can handle. **Q: Can this be used to start a continuous siphon (assuming gravity is in your favor) or does it require hand pumping the whole time?** A: I have not used it in such a manner, I would think it would work once the flow is started. The check valve in the unit is supposed to provide a force flow to the unit, then the fuel pump would take over, or gravity flow if that is the manner of fuel flow. Hope this helps. **Q: is the internal valve spring loaded?are you SURE? just bought one that does not work** A: Yes the valve is internally try to close one side and press the bulb .... vacuum your hand? **Q: My hose says 5/16” ID. Would this 8mm barb fit?** A: My husband says it should. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***N on 3 December 2022* satisfaisant comte tenu de son prix ### ⭐⭐⭐⭐⭐ Review *by F***E on 7 December 2025* Vas très bien ,ils a un se sence pour l’installer avec un entie retour dedans ### ⭐⭐⭐⭐⭐ Review *by C***N on 13 June 2024* Maneggevole e comoda ## Frequently Bought Together - ePathChina 8mm 5/16 Black Primer Bulb Rubber Fuel Pump Transfer Vacuum Fuel Hand Primer Gasoline Petrol Diesel Pump for Marine Boat Accessories - 5/16 Inch (8mm) ID Fuel Line Hose 10FT NBR Rubber Push Lock Hose High Pressure 300PSI for Automotive Fuel Systems Engines - Steelsoft Heavy Duty Hose Clamp Mini Size#4, 5/16 to 1/2 inch Adjustable Worm Gear Drive Hose Clamps Stainless Steel 304 for Fuel Injection Line, Automotive, Radiator, Garden,12 Pack --- ## 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.hr/products/275003841-8mm-5-16-black-bulb-type-rubber-fuel-transfer-vacuum](https://www.desertcart.hr/products/275003841-8mm-5-16-black-bulb-type-rubber-fuel-transfer-vacuum) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-04*
