fuel filter. old one looked like it hadnt been changed in years.cant half feel the difference.much more responsive.
If anyone hasnt changed theres yet,i recommend you do.Only takes a matter of 10 mins.
I was emptying the fuel that was in the old one and it was black rotten and full of shit.
p.s has anyone noticed how much optimax stinks compared to normal u/leaded. been in the shower and i can still smell it on my hands
