I had my car Professionally tuned last week and there is a problem with getting enough fuel when rpm's are up (over 3K) Tuner said flow was dropping by about 30 percent. needless to say he set it up to run a little rich so every now and then I get a nice pop- explosion in exhaust - probably gonna blow my cat out the tail - pipe lol.

I have a boyd tank with their aeromotive pump, everything else is stock, ie injectors, rails, controller, etc. my tuner thinks it may be the piece of hose between the pickup and the pump, he thinks it may be non submersible fuel line and that it has swelled up and is constricting flow. Before I remove my seats, belts, back panel etc I was wondering if anyone has had this issue? I cant remember if I put that small short piece of hose in or if it came made up in the boyd tank?????????? if I did it, I suppose I could have put the gates injector hose there but am not sure if that's submersible. any input is appreciated, it may be something totally different.

thanks,
Doug
