Every car lover wants to bolt in a real toad strangler of a fuel pump. And while the reasons may varyyou want to upgrade your weak stocker, youre planning engine upgrades, youre going racing, you think a billet chunk of metal in your engine bay looks shweetyour reasoning is sound. Because that corroded chunk of metal has lived a hard life, fuel pumps wear out just like everything else with moving parts, and doing it now in the off season sure beats going lean or breaking down next summer. However, your choices are many. Aside from simply bolting up another mechanical pump with a similar pressure rating, youll need some intel into which latest and greatest pump should grace your presence. This is that intel. Fuel Pump Types. Mechanical Pumps CarburetedIn carbureted, naturally aspirated combos, the engine mounted mechanical fuel pump is as simple as it is effective. This old school component uses a rubber diaphragm in the middle of the housing and a metal lever contacting it. The vehicles camshaft has an eccentric lobe that pushes the levers other end, which in turn actuates the diaphragm to pull fuel from the gas tank to the engine. Short Version of Installing mechanical fuel pump. First start after install Disclaimer To the best of my knowledge this video is accurate. I am in no way.

To wit, your smartphone charger, your stereo, and I suppose your headlights or something. Ps3 Call Of Duty 4 Modern Warfare Patch here. Mechanical fuel pumps can be used on NA engines making up to around 4. Electric Pumps EFI and CarburetedThe electric fuel pump is ubiquitous, its used on high powered NA carbureted engines, forced inductionnitrous carbd combos, and EFI applications. Mounted either inside or near the fuel tank, electric pumps hook up using power and ground wires, and use OEM quality gerotor designs or rotorvane designs to push a steady stream of fuel to the engine. As the pressures are higher with electric, a fuel pressure regulator is usually needed. Regarding current draw, electrics for low pressure carbd engines pull only a few amps, but large or multi pump electric setups for EFI engines can pull 2. Electric fuel pumps can easily feed engines that make a couple thousand horsepower. Belt Drive Pumps EFI and CarburetedOn the extreme performance end are engine mounted belt drive fuel pumps. Designed to feed ultra high powered mills running gas or alcohol, belt drive pumps use a pulley and a belt attached to an engine pulley to turn the pump, usually at a certain percentage of the engines rpm. Fmrte 2012 License File there. As belt drive fuel pumps can support 3,0. Corvette probably wont benefit from one. But theyre damn cool nonetheless. And finally, a new type of fuel system emerged recentlyan underhood mounted, EFI sump that ties in directly to a carbd Vettes original fuel system. Be sure to check that out in the guideFuel Pump Installation Locations. Carbureted Vettes can use the factory engine mount location for mechanical pumps, a near tank mount location for carb ready electric pumps, an inline EFI style pump somewhere to the rear but between the gas tank and the engine and even an engine mount location for a belt drive pump. Aside from high powered belt driven race cars, EFI Vettes always use electric pumps. They can use a stock in tank pump with a pump booster, a stock in tank pump with an inline pump, a single large in tank pump and even two and three pump in tank setups. And not to leave out our restomod friends, many of todays high end Vette builds involve dedicated replacement fuel tanks andor fuel cells. Cap Cost Program Download. The best of these designs can incorporate newer, high flow pumps, and use better pickups, modules, filters and lines for trouble free fueling. Fuel Pump Features. Fuel pressure is an important factor during fuel pump shopping, for several reasons. First off, as fuel pressure increases, fuel volume decreaseskeep that in mind if you spot an affordable, high performance pump rated at zero pressure. Yes, fuel pumps have different flow ratings at different pressures. Using late model C4s and C5s as examples, when you see a pump rated at 2. C4s standard 4. 3 psi, that pump may only flow 2. LS engines higher 5. While that 1. 0 percent loss isnt the end of the world, it may make a difference in your pump choice. On carbd cars, running too much fuel pressure can cause bowl flooding problems, which you obviously dont want. Thats why a regulator is often used with carb ready electric fuel pumps. Another important factor is fuel flow. Fuel pumps are marketed with specific flow ratingsmechanical fuel pumps are rated in gallons per hour, or gph. Depending on your make and model, your Vettes stock mechanical pump flows between 4. Electric fuel pumps for EFI applications are rated in liters per hour, or lph. Factory electric fuel pumps can flow around 1. EFI cars, and high performance, late model Vette pumps can flow more than the popular 2. But some performance electric pumps can flow more than 3. Corvette pump kits using two and even three fuel pumps Pumps can be rated for gasoline only, gasohol blends, and alcohol fuels only, so be sure that you choose the correct pump for your application. The wrong pump may not quit immediately when subjected to a fuel that it wasnt designed for, but it will wear out faster. Rotorvane pump designs use a round housing with a rotor and eccentric with vanes. Those vanes push outward on the housing, pushing fuel from the inlet side to the outlet. Theyre a bit noisier, but theyre great for providing lots of fuel at low pressure. Gerotor designs use a gear inside a housing that squeezes fuel as it moves. These designs have tight tolerances, and offer high flowpressure along with very quiet operation. Quality materials can include anodized or billet, which keeps the pump looking great for years. Its good to keep an eye out for a pumps inletoutlet thread sizes, and types like AN or NPT. Many will simply work with your stock connectors, but its good to verify that you wont need anything special to get up and going. Some pumps offer a clockable housing, to allow it to rotate the ports for easier installation. Find out how an electric pumps electrical connectors work. Do they take simple ring connectors on a nut and bolt or a specialized connectorIf its the latter, inquire about purchasing the right connector instead of cutting and splicing ityoull live a more stress free life. We spoke a bit about fuel pickupbe sure to check out the Hydramat in the guide, as its an innovative solution to fuel starvation problems. And finally, find out whats included in the box. A mounting bracket, fuel sock, quality hoses and clamps, extra wiring, O rings and other necessities and new inlet and outlet fittings are some of the things youll want to look for. And your pump may even include a new fuel pump module, replaceable low micron fuel filter and a fuel pressure regulator. Calculating Fuel Flow Requirements. Before you choose the optimal fuel pump for your Vette, you first need to know your target power level. And once you do, youll multiply that number by a certain Brake Specific Fuel Consumption BSFC number to determine your flow needs. The formula looks like this Horsepower x BSFC pounds of fuel needed fuel weight GPHHeres how you do it 1. First, choose the BSFC that corresponds with your engine type Use 0. Use 0. 6 for nitrous engines.
