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

European spec vehicles: The original top hat may need to be transferred over during installation.

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.

Purchased as a gift for my boyfriend's BMW after another pump failed just one day after installation. This fuel pump works flawlessly. Highly recommended!

Good quality.

L
Liam Walsh

Very helpful even after I got the pump. Would recommend buying from them again. Communication is a 12/10.

Devin Carter

Solid kit at a fair price. Install on my E92 went smoothly start to finish, and the included instructions were clear. Fuel pressure is rock steady through every pull, and I am logging exactly what my tuner asked for.

T
Tyler K.

Bolted into my 135i without any wiring modifications, exactly as the listing describes. Running E40 maps for the past few months and consistently logging clean numbers. The pump primes quickly on cold starts and pressure holds steady through every pull.

Scott Johnston
Not bad at all

The part arrived in good shape, with no obvious shipping damage. Exactly the sort of uneventful replacement I was hoping for.

M
Marcus Reilly

Picked this up to replace the failing OEM unit in my 335i and run E50 reliably. Install took about two hours with the rear seat out, and fuel pressure has been flat at WOT ever since. Build quality on the bucket is noticeably better than what I expected at this price point.

Matched the original on my car

I ordered it for a weekend project. I checked the connections twice before finishing the job. A reasonable option if the application is right.

F
Frances Coleman
Would recommend checking fitment

There was nothing flashy about it; it just looked like a well-made replacement. Happy to have the repair finished.

H
Helen Morrison
Fit like it should after installation

Had the car apart already, so I replaced this at the same time. I would still recommend double-checking the exact vehicle application. I checked the installation carefully before calling it done. Not much else to say; it fit and the job is done.

B
Betty Fox
A practical choice

J
Joseph Butler
Solid for the price for this project

Picked this up for a repair on my car. I had to work around some tight spaces, but that was more about the vehicle than the part. Good enough that I would use it on another project.

S
Shirley Taylor
Installed over the weekend

Had the car apart already, so I replaced this at the same time. It looked properly assembled out of the box. The finished repair looks tidy. It met my expectations. I spent more time on removal than fitting the replacement.

P
Philip Meyer
Happy with the fit

Got this for a vehicle I have been working on. No surprises when I held it up next to the original component. The finished repair looks tidy. A reasonable option if the application is right.

Good replacement part

A
Alan Hill
The right part

I needed to get the car back together without making the job more complicated. I cannot speak to years of durability yet, but the initial impression is positive. I took photos before removing the old one.

A smooth replacement overall

Was looking for a straightforward replacement. I was mostly concerned about fitment, and that turned out fine on my setup. It seems like a fair value for the money.

Good purchase on my car

Matched the original so far

Got this for a vehicle I have been working on. I inspected the edges and connections before installation and did not see any issues. I will update my opinion if anything changes over time.
