Hey everyone, I've got a 2000 Civic Si and it's currently running great but I'm trying to future proof the car with some spare parts. One of those parts is the fuel pump. The OEM part is no longer available, is a different part number than other models, and the service manual lists a slightly different spec for the fuel pressure (volume of fuel different?). All the aftermarket part numbers I've found so far are shared across all models regardless of engine. Has anyone replaced their B-series fuel pump and what did you use? I'm thinking a GS-R pump might be close in terms of pressure and volume but I have no idea if they'd be interchangeable. I did search and didn't find anything similar. Any info is appreciated! Thanks!

 

If you just want the OE sized replacement, I would get a Deatschwerks DW100. This pump is a 165lph sized plug and play product, and can be purchased for less than $100.

 

Thanks! I'll check them out.

 

That sucks on the discontinued part. Has anyone used the dc2 version on a 96-00? I recall using one in a 92-95.

 

*Bump*

Thanks again for the replacement pump recommendation but I'd like to get conformation if a DC2 complete pump assembly is interchangeable with my Civic (sorry I was not clear earlier) just in case mine is rusty crusty.

Thanks again.

 

I used this one one my 93si with B16a and in my 95 integra with B20, bolted right in

I believe it is supposed to be 96-97gsr, 110 lph


The pumps are all pretty much interchangeable, only thing that may be different is the sock\filter kit

 

When exchanging the entire pump bracket assembly, you basically have TWO different types in the DC2 chassis. The difference is how the fuel feed line in the car connects to the top of the fuel pump assembly. The early DC2 style, like those found in the '92-95 Civic, has a 17mm banjo bolt fitting at the discharge port on the lid of the fuel pump assembly and the fuel feed line in the car is a banjo fitting. In the later (OBD-2 '96+) DC2 fuel pump assembly, you have the O-ring sealed pinch port style feed line male pipe exiting the top of the fuel pump assembly lid and the chassis has a fuel feed line that slides over the end of this pipe and "clicks" in place... just like the one found in your 2000 Civic.

So, can you use a DC2 GSR complete fuel pump assembly... Yes... but it will have to be a later/newer version that has a lid that looks just like the one found in your Civic. The early/older style is NOT a direct fit... but if your bracket/hangar isn't crusty/rusty... you could still use the older fuel pump and sock itself. Physically, the fuel pumps are ALL interchangeable ('92-00 Civic and '94-01 Integra). The flow rates will be different, but dimensionally you can make it work with very little modification (the rubber fuel feed line between the fuel pump discharge and the pump bracket pipe may have to be lengthened/shortened based on the fuel pump selected).
