Three things that decide the right C7 part
HEUI, not common rail
The C7 uses HEUI hydraulic electronic unit injectors. If a listing calls a C7 injector "common rail", it is mislabeled.
The old part number rules
C7 and C9 HEUI injectors look alike. The stamped number on your old unit — not the engine name — selects the part.
Mixed revisions happen
C7 engines are known to carry different injector numbers across cylinders. Check each unit or send photos of all of them.
Engine FAQ
Questions buyers ask about the CAT C7
Are C7 and C9 injectors interchangeable?
No. They look similar but are not interchangeable — and C7 engines are known to carry different injector numbers across cylinders. The stamped number on each old unit selects the part.
What is the difference between C7 and C7.1?
C7 is HEUI; C7.1 is the newer common-rail series and a different product line. A C7.1 takes 392-9044, not the C7 HEUI numbers on this page.
Which C7 injector number do I need?
238-8091 and 268-1835 are the two C7 HEUI numbers we supply most, with a long cross-reference list. Send the stamped number from your old injector and we confirm before quoting.
Do you supply C7 pumps and kits too?
Yes — HEUI actuation and high-pressure oil pumps (20R1635, 384-0607, 319-0675, T402521, 476-8769) plus internal, external and major overhaul seal kits.

Send the old part number — a nameplate photo is even better. We confirm fitment before quotation.
