The reference linked below may be of assistance. A snipet of which has been copied and pasted. Suggest you contact the USCG directly to be certain.

Boat Building Regulations | Boat Fuel System


"Read the Federal Regulation 33 CFR 183.501-183.590. Federal regulations for recreational boats apply only to gasoline, but I have included notes when the rules for gasoline differ from the ABYC standards for diesel. ABYC has standards for both permanently installed gasoline fuel systems. and portable fuel systems.

Diesel Fuel Systems: The USCG does not regulate diesel fuel systems for recreational boats. However, ABYC does have a standard for Diesel Fuel Systems in ABYC H-33. Contact ABYC (https://www.abycinc.org) for a current copy. There are also ISO ( ISO 10088 can be obtained through ABYC) and Canadian Standards http://www.tc.gc.ca/publications/en/...hr/tp1332e.pdf) for Diesel Fuel Systems."

I too have only found US regulations that pertain to Gasoline, nothing related to diesel. The flammability distinction being an obvious matter for need for safety regulation involving gasoline, whereas diesel is much less hazardous onboard.
