Electric Fuel Pumps by Flow Rate

An electric fuel pump is chosen on three numbers, and only two of them are usually printed in the title: how much it flows (gallons or litres per hour), at what pressure (psi), and whether it mounts in the tank or in the line. This page pulls together 24 in-stock electric fuel pumps from Mr. Gasket, DeatschWerks, Walbro, Holley, Quick Fuel Technology, Edelbrock, Aeromotive, MagnaFuel, Fuelab, MSD and Allstar Performance, from $69.95 to $1,738.78, sorted the way the choice is actually made: 10 carb-pressure pumps (the listings state 14 psi or less), 9 EFI pumps rated in litres per hour (255-470 lph), and 5 high-pressure or race pumps. Every flow and pressure figure below comes from that product’s own listing - including the two listings that publish nothing but a title, which are labelled as such rather than filled in. Every order over $200 ships free.

OUR ELECTRIC FUEL PUMP PICKS

Product	Spec (from the product listing)	Price	Why it is here
Electric Fuel Pump 470LPH Gas/E85	In-tank, 470 lph, E85 / gasoline, Walbro (per listing)	$151.99	The most flow on this page in litres per hour, at a mid-ladder price: the listing calls it the Hellcat pump and rates it 470 lph for gas or E85. If your EFI build has outgrown a 255 or 340, this is the in-tank step up - confirm your hanger and wiring suit it before ordering.
Universal Electric Fuel Pump 4-7psi 35gph	Micro in-line, 35 gph free flow, 4-7 psi, filter included, gasoline, Mr. Gasket (per listing)	$74.99	The carburettor value pick: 4-7 psi is the pressure band a typical carb needle and seat works in, so this pump feeds a mild carb engine without the regulator step the 14 psi pumps below need. Its listing states free flow - flow at pressure will be lower.
DW200 Electric Fuel Pump In-Tank 255LHP	In-tank, 255 lph, install kit, gas / ethanol, listed for Ford Mustang 1985-97, DeatschWerks (per listing)	$109.00	The classic 255 lph EFI upgrade size, sold here as an application kit for the 1985-97 Mustang rather than a bare pump - the part number is the fitment, so check your car against the kit listing, not just the flow number.
Electric Fuel Pump 125 GPH 14PSI	In-line, 125 gph at 14 psi, gasoline, Quick Fuel Technology (per listing)	$189.95	The serious carb pump: 125 gph at 14 psi is strip-grade flow for a carb engine, and at 14 psi it needs a regulator for carb use - Quick Fuel sells the same pump bundled with one, also on this page.
A1000 Electric Fuel Pump	In-line / in-tank, 1,200 lb/hr at 40 psi, 10 AN ports, E85 / gasoline, Aeromotive (per listing)	$549.02	The race end of the ladder: the listing states the flow and pressure and the fuel compatibility, and nothing more - horsepower support for a pump like this depends on fuel, boost and working pressure, so this page prints the listing’s numbers and leaves the horsepower call to those conditions rather than quoting a single figure.

STEP ONE: PRESSURE FIRST - CARB OR EFI?

A carburettor wants low pressure and an EFI system wants high pressure, and a pump built for one does not suit the other without help. The carb-pressure shelf here: the Allstar compact in-line at 18 gph at 4 psi ($149.99), the two Mr. Gasket micro in-line pumps at 28 gph / 2-3.5 psi and 35 gph / 4-7 psi, Edelbrock’s two Quiet-Flo carb pumps with the pressure preset at the factory - 120 gph at 6.5 psi ($295.95) and 160 gph at 12 psi ($307.95), Quick Fuel’s 105 gph pump at 7 psi ($199.95) - and the 14 psi group: both Quick Fuel 125 gph pumps, its 155 gph pump, and Aeromotive’s Street Rod pump (140 gph free flow, with a 14 psi internal regulator per its listing). A 14 psi pump feeding a carb needs a regulator to step it down; one of the Quick Fuel 125s is sold with the regulator included, which is the honest way to buy that combination.

STEP TWO: THE EFI SHELF, IN LITRES PER HOUR

EFI pumps on this page are rated in litres per hour, and the ladder is even: 255 lph (the DeatschWerks DW200 in-tank application kit for the 1985-97 Mustang at $109.00, and the DW250iL in-line at $139.00), 265 lph (the compact DW65c in-tank kit, listed for Scion FR-S / Subaru BRZ / WRX 2012-15), 340 lph (three ways: the Fuelab in-tank, the DeatschWerks DW300 in-tank, and Holley’s Sniper in-tank pump listed for E85), 350 lph (the DW350iL in-line), 415 lph (the DW400 in-tank) and 470 lph (the Walbro in-tank hero above). In-tank or in-line is a packaging decision, not a performance one: the same 255 lph exists here both ways. Where a DeatschWerks listing is an application kit, the application is printed on this page - a 255 is not universal just because the flow number matches.

STEP THREE: HIGH PRESSURE AND RACE PUMPS

Five pumps sit above the street shelves. MSD’s high-pressure in-line pump ($176.95) is the bridge - and its own listing states two different flow figures: 45 gph at 60 psi in its spec line and 43 gph at 40 psi in its body copy, which also rates it at up to 500 hp EFI. Both are printed here rather than smoothed into one; either way it is the one pump here that states a flow at an EFI working pressure. The Specialty Products 115 GPH pump ($92.99) states its flow in the title and nothing else - no pressure, no fuel compatibility - and MagnaFuel’s ProStar 500 ($442.31) publishes no flow figure in its listing at all; both are labelled title-only wherever they appear, and if the missing number decides your build, call us and we will confirm it with the manufacturer before you order. At the top, the Aeromotive A1000 states 1,200 lb/hr at 40 psi in its listing, and Holley’s VR1 ($1,738.78) states 170 gph at 130 psi and is sold with its controller - the ceiling of this page on both price and pressure.

AN HONEST NOTE ON FLOW NUMBERS

Flow figures are not measured the same way twice. Two listings here say so in their own words - the Mr. Gasket 35 gph is a free flow figure and the Aeromotive Street Rod’s 140 gph is free flow too - and a pump’s flow falls as the pressure it works against rises, so a free-flow number and an at-pressure number are never comparable. Units differ as well: this page carries gph, lph and one lb/hr rating (the A1000), printed exactly as each listing states them rather than converted, because a conversion would hide the test pressure the original figure was measured at. Horsepower support is printed only where the pump’s own listing states it (MSD’s 500 hp EFI figure, in its body copy, is the one example on this page) - there is no universal flow-to-horsepower chart on this page, because the honest version of that chart depends on fuel, boost and pressure, and the manufacturers publish it per pump. Also deliberately not here: mechanical fuel pumps, fuel pump rebuild kits, block-off plates, pushrods, brackets and voltage boosters - they live in the parent collection below; this page is complete electric pumps only. Fuel compatibility is claimed only where a listing states it: several pumps here state E85 or ethanol compatibility (the Walbro, the Sniper, the DW range, the A1000) and several state gasoline only.

QUESTIONS BUYERS ASK US

How much pump does my horsepower need? More than the engine’s peak demand, with margin - but the number has to come from the pump maker’s own rating for your fuel and pressure, not from a generic chart. That is why this page prints the manufacturer-stated horsepower figures where they exist and leaves them off where they do not. If you tell us the engine, fuel and whether it is boosted, we will match it against the makers’ published ratings on the phone.

Can I run a 14 psi pump on a carb without a regulator? No - a carb needle and seat works in the low single digits to around 7 psi, so a 14 psi pump needs a regulator stepping it down (or buy the pump-and-regulator bundle on this page). The low-pressure Mr. Gasket and preset Edelbrock pumps exist precisely for setups that want to skip that step.

In-tank or in-line - which is better? Neither, on flow alone: this page stocks 255 lph both ways. In-tank pumps run cooler and quieter inside the fuel and suit cars whose tank and hanger accept them (several here are application kits for exactly that reason); in-line pumps suit fuel cells, sumps and swaps where the tank cannot take a pump. Pick by packaging, then by flow.

Does E85 need a bigger pump? E85 takes more volume for the same power, and not every pump is built for it - which is why compatibility on this page is quoted listing by listing. The Walbro 470, Holley Sniper 340, the DeatschWerks range and the A1000 all state E85 or ethanol compatibility in their own listings; a listing that states gasoline only is not an E85 pump, however close the flow number looks.

What does free flow mean? The flow a pump moves against no pressure - its best-case number. Working flow at carb pressure is lower, and at EFI pressure much lower, which is why an at-pressure rating cannot be compared directly with a 140 gph free-flow unit; they were measured doing different work.
