Product Details

The Kaehler 003-545-25-05 is an aftermarket fuel pump relay engineered as a replacement for Mercedes-Benz vehicles. This relay is responsible for controlling power delivery to the electric fuel pump, ensuring the engine receives consistent fuel pressure during start-up and normal operation. A failed or degraded fuel pump relay is a common cause of no-start conditions and intermittent stalling on affected Mercedes-Benz models.

Key Features:

  • 10-pin connector design for direct plug-and-play installation
  • Manufactured in Germany by Kaehler Automotive Equipment (K.A.E.)
  • Controls fuel pump circuit operation for reliable engine starting and sustained fuel delivery
  • Drop-in replacement requiring no modification

Cross-Reference Part Numbers:

  • Mercedes-Benz OEM: 003-545-25-05 / 003.545.25.05 / 0035452505 / A0035452505
  • Kaehler internal: 3.301.450 / 3301450
  • Additional superseded references: 0035451805, 0025451605, 0035450105, 1012032, 76012032

This fuel pump relay is a straightforward plug-and-play component. It is located in the underhood fuse/relay block and can typically be replaced without tools. Electrical components of this type are generally non-returnable except under an approved warranty claim.

product was as shown

good prices

I think for the part I ordered the shipping price was too high. Needed the part so had to do it.

Great service.

Positive.

Niiiiice

Great!

Smooth so far.

Found the part I needed and it arrived quick.

It was okay. Product doesn't completely look brand new, but I hope it does the job.

Ordering was easy, over the phone or online i was able to find all my parts on Autoplicity conveniently and my order was shipped out in a timely manner. I had concerns that were tended to by a quick phone call and great customer services reps.

Although you should receive a 2 star review, I give it 5 stars only because I should have checked out with paypal before and because of your excellent customer service. Fix the glitch in your system so orders can actually be processed on your page instead

ORDER PROCESS WAS EASY, HOPEFULLY PART WILL ARRIVE OVERNIGHT AS IT WAS PAID FOR.

Really hard to find plugs - autoplicity had over 100 "in-stock" - great price also.

So far its good.

Easy and fast. Liked the option to pay through Amazon.

Good prices free shipping

Fiest time here if it works I ll be back often

Great prices and communication, fast shipping. What more could you want or expect from a company?

easy checkout

you have what i need at a great price

Lowest pricing. very simple process from start to checkout. A+++

By far they had the cheapest prices. I made a mistake on my order and they were able to switch it out for the correct item before it shipped. Amazing guest service over the phone, will def shop again with their low prices.
