Fuel pump oem vs aftermarket?

[sierraspider]

Thanks to all who replied, I put it in and it seems to work, although I didn't put a pressure gauge on it. Bigger problems tho, I seem to have a BIG KNOCK (rod?). Someone said I can just drop the pan,look for loose rod, check crank, and install new bearings to fix the culprit, any thoughts? While I'm there how do I check oil pump and any other things that made need a look at.

As always thanks to all

i would change all the rod bearings while do that not just the bad bearing, you'll need a floor jack some jack stands
to do this. Unbolt the motor mounts then jack the engine up on the bell housing as far as it will go remove the oil
pan the hardest part will be finding a way to pull the pan off working it around the oil pump.
