I bought this pump and i can say first hand that it works great and it over performs, i made 600 wheels on this pump advertised for 575wheels and i had more room left in the pump

Installed without a problem

Got this for a vehicle I have been working on. The first thing I checked was the hardware, and everything looked consistent with the listing.

Deborah Brooks
Back together again

Finally got around to installing this. I checked the connections twice before finishing the job. The finished repair looks tidy. I have only had it installed a short while, but so far so good.

K
Kenneth Scott
Job done

I compared the assembly with the old part before putting everything back together. So far, I am happy with the purchase.

N
Nathan

Installed alongside a JB4 on my F22 M235i. Pressure stays steady and I can finally run the E40 maps without dropping fuel pressure during pulls. Pump primes clean every cold start.

C
Cameron Hayes

Bolted into my F30 N20 cleanly. The OEM pump was struggling on E30 and this fixed the issue immediately. Fuel pressure logs cleaned up the same drive home.

K
Kelly Foster
Matched the original

The fit was right and the finish looked good.

S
Samantha Dunn
Satisfied with the result

The job was not especially fun, but the component itself did not add any headaches. Nothing to complain about so far.

R
Rachel Ryan
Fit was right after installation

Had the car apart already, so I replaced this at the same time. The finish was clean and I did not notice anything bent or loose. It seems like a fair value for the money.

D
Dylan Davis
Solid for the price

Bought this while sorting out a few things under the hood. It looked properly assembled out of the box. Not much else to say; it fit and the job is done.

J
Jack Carter
The install went well

I wanted something that matched the listed application. The supplied part matched what I had ordered.

S
Sean Washington
The right part

This was part of a larger maintenance job. The dimensions were close to what I expected from the product description. Not much else to say; it fit and the job is done.

S
Sophia Cunningham
Good first impression

I was comparing a couple of options before ordering. It looked properly assembled out of the box.

E
Ezra Martinez
Quality seems good

My old unit was due for replacement. The dimensions were close to what I expected from the product description. I would buy it again if I needed the same part.
