This may not be new but since I have installed my silencer (End cap on muffler) I noticed a knocking noise from inside the car that I could not hear before or outside of the car.

After some time trying to figure out what was wrong I put my hand on the fuel line and noticed the pulsations on the line match this knocking sound. It seems to be that the fuel is pulsating in the lines? Is this normal or bad?

This is on a 255lph fuelpump on parrallel fuel system on an aeromotive fuel pressure regulator. -6an lines on stock fuel lines to tank and from tank.

Thanks,

Maybe its time for a pulsation damper? Try Marren fuel injection.

 

They say you need one for each frame rail? Is this nessary. Say you just T it to the fuel splitter before the fuel rails?

Now I have to try and find room to install this. To bad its not something you can install near the fuel tank.

Damm, that sucks dude. With your bling bling setup I did not think this would be necessary...hmmm

 

True. Very true. The only way I can see my setup being different then yours is that your capacity is more. IE your fuel filter and bigger lines etc.

This is pretty much the last straw. Its bad enought having absolutely no boost response!

Untill next year..........
