DeatschWerks 430 LPH Low Pressure Fuel Pump - 2016-2026 Honda Civic / 2023-2026 Acura Integra

Here's a spot a lot of people overlook when they're building a turbo Civic or Integra. Everybody upgrades the injectors and tunes for more boost, but the fuel pump back in the tank is still the factory unit, and on a direct injection car that low pressure pump is feeding the high pressure pump that actually sprays your injectors. If that in-tank pump can't keep up, your whole fuel system runs out of headroom no matter what else you've done. You hit a fuel ceiling and the car won't make the power you built it for, or worse, it leans out when you're leaning on it. The DeatschWerks DW430C drops right into your tank and fixes that. It flows 430 liters an hour, way more than the factory pump, so your fuel system's got the volume to actually support the power you're chasing. And it's fully E85 compatible, so if you're running ethanol or planning to, this pump's ready for it.

Here's Why The Factory Low Pressure Pump Becomes A Bottleneck

On these 1.5T and 2.0T direct injection engines there's two pumps in play. The high pressure pump on the engine builds the big pressure that fires the injectors, but it can only work with what it's being fed. That feed comes from the low pressure pump sitting in your fuel tank. From the factory that in-tank pump's sized for a stock car. The second you add boost, bump the injectors, or switch to E85 (which burns a lot more volume than gas) you're asking for way more fuel than that little factory pump was ever meant to move. It maxes out. Then your high pressure pump starts running short, your fuel pressure drops, and the tune pulls power to protect the engine. Dropping in the DW430C gives the whole system the volume it needs so you're not capped by the weakest link in the chain.

430 LPH And Built For E85

The DW430C flows 430 liters per hour, which is a serious jump over the factory pump and plenty to feed a built 1.5T or 2.0T. But flow's only half of it. DeatschWerks builds this pump with ethanol-safe internals, so running E85 won't eat it alive like it would a pump that wasn't designed for it. That matters because E85's where a lot of these Civic and Integra builds end up, since it's basically cheap race fuel and these turbo motors love it. Whether you're on pump gas now or you've already made the jump to ethanol, the DW430C handles both without complaint. And it runs quiet and efficient, so you're not adding a bunch of pump whine to the cabin.

Drops Right In - No Surge Tank Needed

This is an in-tank low pressure pump, so it goes right where your factory pump lives. You're not fabricating a surge tank setup or running external pumps and plumbing to get more fuel. It's a direct upgrade in the stock location, which keeps the install clean and keeps your fuel system looking and working stock from the outside. For most people building one of these cars, an in-tank pump upgrade like this is exactly the right move before you ever need to think about a surge tank.

Why DeatschWerks

DeatschWerks has been doing fuel system stuff for a long time and they've got a real reputation in this space. When you're upgrading the fuel pump on a car you're pushing, this is not the place to cheap out, because if the pump quits or can't keep up, the engine's the thing that pays for it. A lean condition under boost is how motors get hurt. DeatschWerks pumps are proven in builds all over the place, and the DW430C carries that same track record. You're putting in a pump that does its job and keeps doing it, which is exactly what you want feeding a motor you've spent real money building.
