Hi All,

Been having a strange fuel overflow issue with the 86.

Basically I fill her up like usual, drive her home and a couple of hours later I find a puddle of fuel on the ground.. Upon closer inspection the fuel is actually coming out of the fuel tank opening while the fuel cap is still locked in place. I removed the fuel cap while it was leaking and fuel gushed out (nothing crazy) and the fuel neck was full to the brim. Had to siphon out a good 500ml to get the fuel level down to the point where I couldn't see it. The car runs pretty well so, fuel supply isn't an issue. The 4AGE conversion was done in Feb and this overflow problem has come up 3 times.

Just a little worried I'll blow myself up while driving her, and its also a bitch getting that fuel smell out of the cabin.

Could it be pressure build up in the tank caused by something dodgy in the fuel system, or a crapy seal on the standard ADM fuel cap, it does wobble a little when its in the locked position. Could I be overfilling the tank, only ever get to one click at the bosser and I stop (only use 98RON). Driving me nuts trying to figure it out...

Does anybody out there have any idea what could be causing the problem?????

Bit of background on the car:
> Engine converted to JDM 4AGE (Blue & Blacktop)
> Inline fuel pump still using ADM lines with EFI hoses (fuel system conversion done by Toyospares in VIC)
> No unleaded filler adapter fitted (was told it was fine as is and should pass Engineering)

Any input would be appreciated

Cheers

Josh
