What's the part number for the rubber hose in the picture for the return line that has the black ziptie, and the hose connecting the two circled pipes? On a '06 Evo IX MR
Yeah I'm using EPC Data to get part numbers and realized I was looking in the wrong section. I'm actually replacing a Buschur Double Pumper and it's lines with a stock housing + Walbro 450.
I think it’s just 1/4 fuel line. You could just buy a few feet and cut it yourself. Use a hose clamp at the ends or it looks like you could use a 3/8 bundy female quick connector. You should double check those sizes, but I think that’s what the stock sizes are.
Yeah (05265B MR573026) looks like the rubber line with the two zipties (that's a positive battery cable, the left circle in the first post actually was already dripping fuel)
05412 MR556882 I think is the high pressure feed line (which should be a 5/16 hard line. I'd rather use a OEM part or at least female quick connects. Would something like this be okay?
I think you’re right. The stock fuel feed line is 5/16 and the return is 1/4. I’ve only personally messed with the return line to rig up an ethanol content sensor.
edit: post #22 of the thread linked looks like some of the info that you need. This person says the under car quick connect fittings are 5/16 like you said and that the pump housing has 3/8 fittings. https://www.evolutionm.net/forums/ev...l#post11593967

Yeah thanks a lot for the link, I like pal215's thinking that the 3/8th quick disconnect from pump housing -> -6AN hose to 5/16th hardline will eliminate a (small) fueling bottleneck. Plus the factory line isn't something I expect to be sitting at a dealership (IF the warehouse even stocks it, I have a feeling it would take and cost the same as just ordering the AN fittings/quick connect adapters). Car is only gonna make 4-500whp but I'd like to do it right once.
Wiring on the double pumper is wrecked (poorly done to begin with, cracked/fraying), fuel lines are leaking, 255s aren't rated for E85 (going Flex Fuel), and for simplicity's sake (1 pump vs 2 pumps).
I'm running a 12v rewire w/Hobbs Switch, had a friend of mine who's a electrical engineer do the work. We got 10.5v low voltage and a little over 14v high voltage on a Walbro 450 274 pump in a stock housing w/the siphon drilled out to 9/64"

Thanks
Thats just a normal rubber fuel hose. Nothing more nothing less. The OEM rubber is the same. I just threw mine out last week actually.
