Replacement or aftermarket fuel tank, IJSBA

Almost never a free swap. The usual allowance is an unmodified tank from ANOTHER homologated PWC.

This page is IJSBA only, and the bodies do not agree. The same part under IHRA and UIM. Which one applies to you is decided by whoever sanctions the race you enter.

Where it stands, class by class

20 classes, grouped where the same rule gives the same answer rather than listed one by one, because an answer that holds for a class usually holds for every class that borrows its rules.

What each answer below means

OEM part required
This comes off. Only the part the manufacturer fitted is allowed here.
Not permitted, not listed in the rules
Treat it as coming off. The class requires the craft to stay stock except where the rules allow otherwise, and this part is not on the list, so this is our reading rather than a rule we can quote at you.
Legal, with conditions
Keep it, but measure it: the rules permit this part only inside stated limits.

OEM part required 1 class

Rec Lites prints no fuel tank clause, and the craft must remain strictly stock with unlisted changes not permitted, so the original tank stays. · RRL.1.1

OEM part required 1 class

OE filler and relief valve required, unmodifiable. No tank replacement listed.

OEM part required 1 class

The original fuel tank, pickup, filler, filter, tap assembly and relief valve must be used unmodified, and only the filler cap may be modified or aftermarket. The held text prints this clause as 6.5.2 inside RAS.6, where the class numbering makes it RAS.6.2, and the four-stroke fuel section has no tank clause, so RAS.1.1 keeps a four-stroke tank stock as well. · RAS.1.1, RAS.6.2

OEM part required 1 class

OEM tank, pickup, filler, filter, tap assembly and relief valve, unmodified. · SKL.4.2

Not permitted, not listed in the rules 1 class

No fuel tank section exists.

Legal, with conditions 4 classes

Permitted, subject to the limits IJSBA applies to every class, namely the sound ceiling, the hull repair tolerance, and the intake grate and sponson dimensions.

Legal, with conditions 2 classes

An unmodified tank from another homologated PWC; a non-homologated aftermarket tank only by race director approval meeting or exceeding OEM strength and safety.

Legal, with conditions 1 class

IJSBA-approved aftermarket fuel tank, filler and relief valve. · SKM.5.1

Legal, with conditions 1 class

The fuel tank may be modified or aftermarket provided the craft cannot vent or spill fuel at any attitude and the tank is securely fastened to the hull, and the filler may be relocated. The same clause also keeps the narrower wording that limits a replacement to an unmodified tank from another homologated PWC or a race director approved aftermarket tank. It sits in the two-stroke fuel section, and the four-stroke section has no tank clause. · FREST.4.4, FREST.4.7

Legal, with conditions 1 class

Two-stroke only for non-homologated aftermarket tanks. · SPGP.7.4

Legal, with conditions 1 class

Completely aftermarket tanks upon IJSBA approval.
