Q:The specs say without pressure sensor is there one fuel pump for a Mazda 3 2010 2.0 that come with it, driving in California I think I'm gonna need it, wouldn't my car fail smog test every time if it doesn't have the pressure sensor? Show Less
Lombardo M.
A:BEST ANSWERHi Lombardo, I'm pleased to assist you. A 2010 Mazda 3 2.0L does not have a fuel pressure sensor as part of its fuel pump system. Instead, it uses a fuel pressure regulator to maintain the correct pressure in the fuel system. The absence of a fuel pressure sensor does not necessarily mean that your car will fail a smog test in California. Smog tests primarily measure the emissions produced by a vehicle, and the fuel pressure sensor is not directly related to emissions control. You can use the link below to directly place your order while supplies last. I hope this helps, and happy shopping! https://www.carparts.com/fuel-pump/drivemotive/rm31450006?can=CPGG4850_CSQA_20231108 Show less

Q:We’re is fuel pump located ?
Jackie W.
A:BEST ANSWERHi Jackie, Nowadays, the fuel pump is located inside the tank with sending unit included. But way back in the early 1980s, the fuel pump is separate from the fuel sending unit and is located outside or inside the fuel tank. Still, we recommend referring to a trusted vehicle specific repair manual for details about this fuel pump. You can find more information here: https://www.carparts.com/blog/why-you-should-always-consult-a-repair-manual/ Show less

Shopping for Mazda Fuel Pump

Your Mazda is built to perform at the highest level of quality there is. But while it’s designed to be one of the best,  some of its parts can get damaged over time. One example is the fuel pump, which is responsible for delivering gas to the engine’s fuel injectors.

Contaminated fuel, clogged or dirty strainers and filters, and electrical faults due to rusted connectors and melted wiring are common issues that could shorten the service life of your Mazda’s fuel pump. These could cause your vehicle to exhibit symptoms like surging, power loss, reduced fuel economy, and sputtering, among others. In some cases, a bad fuel pump may prevent your vehicle from starting一as if it were out of gas.

To keep your Mazda performing at its best, make sure to replace its faulty fuel pump as soon as possible. Here at CarParts.com, we have a wide selection of Mazda fuel pump replacements for various models. These pumps are available in different inlet and outlet types and fuel sending unit configurations.  All products come with a low-price guarantee to help you get your vehicle back on the road while keeping repairs costs low.

For a hassle-free shopping experience, you may order through our website or use our toll-free hotline anytime. Our lines are open 24/7.

Start shopping by entering your Mazda’s year and model into our vehicle selector. For instance, if you’re looking for a Mazda 3 fuel pump, simply enter those details to narrow down the search results to compatible products for your ride. Shop now and take advantage of our unbeatable prices!
