New DW400 fuel pump poor fitment
Dw part #9-401-1041 new big boy bosch pump 94-05 miata kit
Anyone using this pump? The sock they send with it isnt even close to same size or angle as the oem (and dw300 for that matter)
And there is no rubber isolator for the bottom ao the pump has nothing to sit on
Dw300 vs dw400

Yes the fitment is bad, just like the Walbro450
Most threads I've researched reused the OEM bushing, threw the isolator sleeve over the pump and clamped to the pump cover assy,
I did this when I put mine in:

Seriously? The DW300 is the same physical size as a stock pump with the same inlet/outlet diameters. The DW400 is substantially larger and requires that you put on your big boy pants to figure out the install.
This thread is like buying 15x11s and whining about the "poor fitment".

Its taller. Thats it. I can cut the inlet pipe on hanger no biggie.
Its bigger around but doesnt contact any part of the hanger when placed in the center of the bottom hanger bracket.
And what do you suggest I do about the sock?

I suggest that you put your big boy pants on. Using a DW400 implies that you're building a 500whp Miata. It's not Legos. If you can't figure out the fuel sock, you may have bitten off more than you can chew.

Nice work. Picked up a DW400 recently and will be returning it for the Walbro 450 pump mainly due to the fuel sock starvation issue and general fitment. Talked with a DW Technical contact about the issue and they didn't really acknowledge the fitment issues, only saying the rubber isolator isn't needed as the pump "isn't noisy" and the Miata tanks have their own "fuel slosh issues". No mention of Savantington's big boy pants. My issue is that this really shouldn't be advertised as being for a Miata at all, in the way that the DW200 and DW300 had literally "drop in" fitment.
