Nasty Performance makes one. Its technically for a 4th gen, but it will fit, you need the 4th gen filler assembly.
It fits ok, the 3rd gen tank straps are short though. It uses a tube style sending unit, has 2-1/2 FNPT outlets in the sump, a 3/8" FNPT return and 1/4"FNPT vent. It doesn't play nice with you exhaust or heat shields, you will have to modifty things a bit.
The only complaint i have is they apparently dont baffle the vent connection. So fuel can slosh out unless you get creative.
there are mounting provisions on the driverside for a fule pump, but i dont know which pump is sopposed to fit there. I though the a1000, but no.
