2G Help! DW300 Fuel Pump install!

[Raab1]

Hey guys, I wasn’t sure what section to put this in. But I have my fuel pump assembly all put back together with the dw300 mounted on it, and was about to throw it in before work here but figured I should pump the brakes because I don’t want to do this again and want to make sure I did it right since the instructions aren’t the best and the closest videos I could find was the wally255 videos everywhere, and a write up from maperformance right when the dw300s were about to come out and I saw that they were making changes in the install kits early on. So first of all my car is a 2g Gsx. The install kit came with the sock (went on no problem), o ring lube and 2 o rings. These plastic pieces off my stock pump (I’ll post a pic below) is what I used with just one of the two o rings. The white piece cracked trying to put clip it onto the new one as it seems to be a little bigger on the dw300. I got it to clip on and installed it anyways. The o ring was a son of a gun to get in there too, it was tighter than heck.

I just want to make sure I’m good to go with this as I saw a dw300 video for an evo and they used both o rings and that was it. Do I need to put both o rings in? Do I use the white and black plastic pieces from my stock pump? I’m hoping to throw it in tonight after work. I know a bunch of guys are running them I just don’t know why there isn’t much for write ups on them specifically. So if anyone knows please let me know! Thanks!!

I cut the tip off and installed a fuel line with hose clamps. If you go this route, make sure to use proper fuel line.

Hello, I assume by now you resolved your question. But just in case someone else has the same problem/issue, I just installed a new DW300, kit #9-301-0847 yesterday, to replace my old Walbro 255. The O-rings DW300 supplies are way to big to use in our 2G DSM hanger's inlet where the DW300's outlet pipe goes into. I used the smaller o-ring from my old Walbro's outlet (which was in perfect shape) along with the same two parts you have pictured in your post. See the pic below. Hope this helps someone out:
