EKP Compatibility Notice

Upgraded pumps draw more current than stock, so if you're on a weak or aged EKP2, it may overheat and shut down. We recommend upgrading to an EKP3.

Installation Notes

Required tool: A fuel pump lock ring removal tool is required for installation. Our Fuel Pump Lock Ring Removal Tool for BMW E-Chassis and MINI is available separately - add it to your order from our store.

Good first impression

Was looking for a straightforward replacement. No surprises when I held it up next to the original component. So far, I am happy with the purchase.

Aaron W.

Install was a tight fit in the E60 tank but everything went together cleanly. Pressure holds well and the car pulls hard now. Solid kit overall.

Roy Johnston
A practical choice so far

Picked this up for a repair on my car. There was nothing flashy about it; it just looked like a well-made replacement. I checked the installation carefully before calling it done. No complaints from me at this point.

Joel Fitzgerald

Went FBO on my E60 535xi and stepped up to the 535 pump at the same time. The bucket is leagues ahead of the OEM unit, and pressure stays steady well into the rev limiter. Easy recommendation for anyone past the 500whp mark.

Would order again

I cannot speak to years of durability yet, but the initial impression is positive. So far, I am happy with the purchase.

So far, all good after installation

I was comparing a couple of options before ordering. The dimensions were close to what I expected from the product description. Nothing to complain about so far.

Austin Moore
Good overall

Finally got around to installing this. The packaging was decent and the part was protected well enough. For my project, it worked out well.

Austin Coleman
Fit was right

This ended up being the part I went with. The first thing I checked was the fit in the housing, and everything looked consistent with the listing.

So far, all good

Was looking for a straightforward replacement. The finish was clean and I did not notice anything bent or loose.

Aurora Payne
Better than expected

Bought this while sorting out a few things under the hood. I had to work around some tight spaces, but that was more about the vehicle than the part. I checked the installation carefully before calling it done. I am satisfied with how it turned out.

Amy Carr
Good first impression on my car

Had the car apart already, so I replaced this at the same time. I compared the connectors with the old part before putting everything back together.

V
Virginia Perkins
Satisfied with the result

I took a chance on this after checking the specifications. I was mostly concerned about fitment, and that turned out fine on my setup. Everything went back together without a surprise. It seems like a fair value for the money.

M
Madison Johnson
Satisfied with the result

This was part of a larger maintenance job. I took my time with the installation rather than rushing through it. Exactly the sort of uneventful replacement I was hoping for.
