Description

1988-1990 Dodge Cummins 5.9L Diesel Fuel Injector with 7mm Nozzle Tip

CDC #’s 3919347, 3802365RX

Chrysler/Mopar #’s R4720540

This injector fits 1998-1991 non intercooled engines that have a 7mm injector tip opening in the cylinder head. These Dodge Cummins fuel injectors can be used with 9mm cylinder heads but you must also purchase 6 injector sleeve adapters part # 3919358. Due to cracking issues there was an upgraded cylinder head and injector combination using the smaller 7mm nozzle tip instead of the 9mm. These are the injectors that would be used if the cylinder head upgrade was performed.

These injectors are rebuilt by Huckstorf Diesel with brand new Bosch nozzle tips and set to the proper opening pressures. 245-255 Bar or 3553-3698 PSI

6 Required for a full set. Each injector includes a nozzle gasket, return line gaskets, and dust shield.

Nozzle gasket number = 2430105009 or F00VC17503. 9 mm x 1.5 mm.

Huckstorf Diesel is a Bosch authorized diesel repair facility and only uses genuine Bosch nozzle tips when rebuilding these injectors. There are lower cost alternatives out there but the lower quality is not worth the savings! The injectors are critical in the proper operation of a diesel engine. The spray pattern of fuel into the cylinder has determines how the fuel and air mix and burn. If the angle and the atomization of the fuel is not perfect, performance and mileage will suffer. Huckstorf Diesel sets the opening pressures to a very tight tolerance for balanced sets and smoother running engines.

If we do not show availability in stock, we are waiting for cores to be returned and / or do not have one to rebuild.  We can rebuild and return yours and core charges are not required.  

Core Charges

This part requires an acceptable matching rebuildable core be sent in to avoid paying the core charges.

With Core Option = Means you will pay the core charge up front, and when an acceptable core is returned to Huckstorf Diesel the core charge will be refunded back to you.  An acceptable matching core must be received within 30 days of the ship date to receive full core credit.

Without Core Option = An acceptable matching core must be received before the exchange is sent out.

An acceptable core is one that is rebuildable with typical replacement parts.  Major damage such as rust, housing damage, critical broken parts will be cause for partial or no core refund.  If you have any questions on this policy please call or send your injectors in first for inspection.  Normally an injector that comes off a running engine in need of typical repairs is fine.  Injectors that sat for years in junk yards, fire damaged, collision damaged, etc. may not be accepted.

We are always looking to purchase good cores.  Contact us if you have any rebuildable cores to sell.
