HMT plug wire covers

Re: HMT plug wire covers
Not running well at the track these days. First I thought it was due to my plug wires cooking.
Turns out, my fuel pressure is dropping under boost. I am running two fuel pumps. A mystery 190 lph in tank pump and then an in line procharger pump that is like 240 lph. With the fp regulator that I'm running, the pressure should increase 1 psi per psi boost. So under boost, my fp goes up but as the rpms increase it falls back and the car starts bucking in 3rd and 4th. I see a new fuel pump in my future. I tried changing the filter and it helped a little but it still loses pressure.

I had that mystery problem when I first tried to tune my car
Id keep adding fuel in TE but the a/f would just skyrocket under boost, changed a few fuel related things
One day I went out and tried another pull, I killed the car after about 6psi, pulled over to check the plugs
Whatdya ------- know, someone stole or I forgot to reinstall my ------- gas cap and gas was coming right the ---- outta the cap and was down the side of my car!!!!
Probably not your problem, but ---- was I ever pissed
