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.

Better than expected

The original part had seen better days. I checked the connections twice before finishing the job.

If you have an E6X and you're chasing serious power, this is the kit to get. Plenty of fuel volume for what I am running, build quality is on point, and the install video posted online was genuinely useful.

A practical choice

I usually spend a while checking fitment before ordering parts. The finish was clean and I did not notice anything bent or loose. No complaints from me at this point. I did the work myself.

Arrived in good condition after installation

I was comparing a couple of options before ordering. The part arrived in good shape, with no obvious shipping damage. The finished repair looks tidy. Would consider this brand again for another repair.

Installed over the weekend on my car

Was looking for a straightforward replacement. The supplied part matched what I had ordered. I will update my opinion if anything changes over time.

Exactly as described

Picked this up for a repair on my car. I compared the assembly with the old part before putting everything back together. Everything went back together without a surprise. Would consider this brand again for another repair. I spent more time on removal than fitting the replacement.

reasonable value

I ordered it for a weekend project. The installation went more smoothly once I had the old part out.

Fits my setup

Had the car apart already, so I replaced this at the same time. The installation went more smoothly once I had the old part out.

Installed over the weekend

I usually spend a while checking fitment before ordering parts. I checked the connections twice before finishing the job. For my project, it worked out well. The hardest part was getting access to the old component.

What I was looking for

This was part of a larger maintenance job. The job was not especially fun, but the component itself did not add any headaches. I checked the installation carefully before calling it done. No complaints from me at this point.

Pleased with this one

I needed to get the car back together without making the job more complicated. I inspected the edges and connections before installation and did not see any issues. It seems like a fair value for the money. I did the work myself.
