We specialise in high-quality remanufactured injectors and fuel pumps for cars, trucks, tractors, and other diesel-powered equipment. The full list of vehicle and machinery types we service is on the About page.

Use the vehicle selector to match your make, model, year, and engine, or search directly by the OE/part number. If you are unsure, contact us before ordering on +359 895 343 537 or office.dieselsolution@gmail.com — our team will help you choose the right part for your vehicle.

Yes. The vehicle selector walks you through make, model, year, and engine and shows the injectors that fit. You can also search directly by part number from the search bar.

New injectors are sold without any deposit. For remanufactured injectors and fuel pumps, you either hand your old parts to the courier on delivery, or pay a refundable deposit — €50 per injector or €150 per fuel pump — until you send them back. The deposit simply guarantees that your old parts come back for remanufacturing.

Remanufactured parts ship with a swap-on-delivery condition: the courier collects your old parts when you receive the shipment, unless you have paid a deposit. If you paid a deposit for a later return, send the old parts in person or via any courier within 30 days.

Recipient: Diesel Solution, 66A Okolovrastna St, Kazichene 1532, Sofia, Bulgaria.

Return transport is paid by the sender.

Please check the acceptance criteria on the Deposit system page before sending your old parts: the unit must be complete and free of mechanical damage, with an intact electrical plug, no heavy corrosion, and a legible part number.

Once the returned parts pass inspection, the deposit is refunded within 3 to 5 business days, using the same payment method you paid with.

If the returned parts do not meet the requirements, the deposit is not refunded and the parts remain with us for eco-disposal.

In-stock orders are dispatched from Sofia within 24–48 hours on business days. In Bulgaria delivery is free with Econt and usually arrives within one business day. To the rest of the EU we ship by tracked courier such as FedEx for one flat rate shown at checkout, typically 1–3 business days after dispatch.

If your shipment is lost, delayed, or damaged, contact us immediately. We open a claim with the courier and aim to resolve it within 5 business days; if it is not resolved by then, we send a replacement. Shipping costs caused by delivery problems are on us.

Cash on delivery is available within Bulgaria only. Everywhere we accept bank transfer, debit or credit card, and online payment through the checkout; approved business customers can pay by invoice.

We offer a 1-year warranty covering material and manufacturing defects under normal use. Full details on coverage and the warranty procedure are on the Returns & warranty page.

It does not cover improper use, incorrect installation, contaminated fuel systems, damage from a defective fuel pump or turbocharger, ECU or tuning changes, non-original fuel filters, normal wear, or unauthorized modifications. The full list is on the Returns & warranty page.

No. We accept only removed (dismounted) injectors and fuel pumps for testing and repair. Vehicle diagnostics and part removal are not services we offer.
