DW300C Fuel pump for BMW E30

The included install kit saved me a ton of time fitting this to my '89 325is—everything lined up perfectly. The 340lph flow is more than enough for my stock engine, but I like having room for future upgrades. Feels solid and runs quiet so far.

Plumbed this into my E30 M3 over the weekend and the 340lph flow is a noticeable upgrade over the stock pump, especially with the included install kit making the swap straightforward.

Was a bit worried about the fitment, but the included install kit made swapping the old pump on my 325is straightforward. The 340lph flow is a noticeable upgrade, and the pump runs quietly even under load.
