00 mountaineer 5.0 fuel pump??

[cashmoney37]

Can a weak fuel pump cause detonation? higher rpms and 3/4's to full throttle I get a real loud detonation sound. Its a 00 mountaineer 5.0.

Does walbro make any upgraded fuel pumps for our trucks?

I had issues with a weak fuel pump and detonation at WOT. I replaced and was fine for about 6months and the new one failed. I pulled the fuel filter and there was a fine black dirt that came out. My guess I was getting dirty gas from somewhere and burned up both pumps. I cleaned the tank out along with new filter and new pump and haven't had a problem yet.
