BenzForce is proud to be associated with Dieselmeken and represent their brand in the USA. We acknowledge their legacy in this market and do everything we can to live up to their standard.  BenzForce upgrades om617 MW and mechanical om603 pumps using Dieselmeken P&Bs (elements) and ALDA system (M pumps).  We do not resell prebuilt pumps from Dieselmeken.  Our pumps are built in Texas and made available to customers in North America.

Dieselmeken, we warranty the elements in all pump upgrades for the lifetime of the pump.

• All other workmanship, seals, gaskets, etc associated with the upgrade have a 90 day warranty.
• Warranty is void if evidence of non-diesel fuel can be found or there is evidence of calibration tampering not discussed with us.
• Warranty is only extended to the original purchaser and is non-transferable.
• Customer is responsible for shipping charges to BenzForce for warranty work, we will pay return shipping.

Exchange Process

Currently we work on an exchange basis, meaning we do not build pumps on a customer request basis.  This is how the exchange works:

• Purchase the pump online.
• Your core must be received within 30 days or the order will be canceled.  
• In the event the order is canceled because the core was not received within the 30 day window, yet a core is received after cancelation, the customer will be required to pay return shipping for their core.
• The core should be in good operational shape.
• If there are issues (rusty camshaft, broken case, etc. we will reach out to you to discuss.
• Be sure to keep all your banjo fittings and linkage parts
• It is suggested you insure your pump and make sure all oil is drained and it is bagged so it will not leak.  We have had carriers throw leaking cores away with no reimbursement.
• Please pad your pump so it does not get damaged.
• om603
  • EDC Pumps are not accepted as M pump cores, the core must be a om603 or om606 NA mechanical pump with a threaded inlet - not a fitting to receive a plastic fuel line.
  • The electrical connector on the high idle (red) magnet must be intact
  • The lift pump is not required but we need the nuts and washers are
  • We would appreciate the ALDA if you no longer need it
  • The shutoff valve must be intact and not broken
• om617
  • MW pumps with a rack position sensor will not be accepted
  • The ALDA must be good and included with the pump

Other Information

• We no longer resell parts for pump building
• We do not build 5 cylinder M pumps at this time
• Generally there is no ETA on when pumps will be available.  Batches are usually offered 2-3 times per year.
• To be notified when a pump becomes available, use the Notify Me button on the product listing page.  You can also watch for Facebook page or Instagram posts which are made prior to the pump going into inventory.  Pumps, especially MWs, sell out very fast.
