so last night I took my05 stage 2 sos out for a drive and while getting on the freeway I did a full throttle pull then out of no where the whole car just did a major hic up.... like the motor just died for a quick second then I just went to normal. I know that's not normal and not belt slippage.. so I went home open up the hood and I see some white residue at the end of my fuel line where it connects to my fuel rail.. can it be leaking fuel??? And can it cause that major of a hic up??

 

Might have missed or knocked pretty hard. Get it fixed and see if it goes away.

not sure why it would be white though!?!?! Or residue. I would inspect the pump sock and take a flashlight and look in the tank make sure nothing nasty in there. You could use compressed air as well to check fuel lines and return.
