WARNING! This isn't your father's in-tank pump.
Conventional wisdom used to be not to worry too much about getting "too big" of an EFI fuel pump. After all, the fuel that isn't used is returned to the fuel tank, right?
Well, be sure that this fuel pump IS too big for most applications. Not only is this the first fuel pump of its kind to crank out an amazing 400 liters per hour (lph) of fuel, but it is enough to overwhelm the stock fuel lines on most vehicles. What this means is that the puny return line on most vehicles will alone create enough resistance to this massive flow of fuel that you will not be able to turn the pressure down to what your engine is looking for. If you don't replace the return fuel line you will be running pig-rich as 400 LPH of fuel takes the path of least resistance, into your engine.
Ok, so I've got you a little concerned? Good. If you are not making over 600 horsepower (naturally aspirated) or well over 500 HP (turbocharged), then we have the perfect fuel pump for you--but not on this page. Either use our Walbro Fuel Pump Lookup App for a 255 LPH direct replacement to your OE fuel pump or else visit our Walbro 255 LPH Inline Fuel Pump page to get a fantastic pump for your performance vehicle.
Still reading? Ok, great! Here are a few things to keep in mind. First, this is not an direct-fit, OE-replacement fuel pump kit like we sell elsewhere on the website. This kit is for individuals with the capability and desire to modify their existing in-tank setup to work with the new Walbro DCS 39/55 400 LPH high performance fuel pump you see pictured above. Included in the kit are some basic components that you will likely require, shown in the picture below.
thats why im asking...? lol

I wouldn't recommend a aero 340. They over heat. I have one sitting in the shed. I replaced it with a walbro 400.
I'd go with a walbro 255 the gs340 I think is the one you would want. It's the center inlet high output 255. It will work with your mods.
