Instructions for installing the 90 degree fuel tank fitting for all 2012-2022 KTM and Husqvarna 250/350/450/500/501 bikes and TPI models.
In the kit, you get both a black (shorter) inside piece and the silver (longer) inside piece. The silver one fits the thicker stock tanks, found on 2012-2019 EXC and FE bikes and also the XCW-F models.
The black one allows you to fit the 90 to any aftermarket oversize tank, which is normally thinner plastic. The black one is also the one you use for the thinner stock tanks on the SXF / XCF / FC / FX and TPI Bikes.
All 2020-22 bikes and all TPI bikes use the black fitting.
You don’t need to get the fittings exremely tight. A slight movement when tight is good as it allows some flex upon a big crash or impact, which may help keep it from breaking off.
This 90 tightens down with a 1/4” ratchet.
