o2 sensors Gen 1

[99 R/T 10]

Just so you know, the wires that were arcing on me were the MSDs, relatively new too(8 month old). Just saying...........

The Gen 1 is non-return, so the pump cannot be suffering from hot fuel returned from the engine. If it is making a different noise, perhaps it is either failing to provide pressure when run for a while, or pushing too hard against a plugged filter. A quick, cheap thing might be to replace the fuel filter.

All right, my issue is fuel pressure. I am going to try Tom's suggestion and replace the filter, but I am guessing its the pump. PBJ just put in a Walbro 255 less than a year ago, and I have driven the car about 1800 miles since the install. Are these pumps that weak??

[Tom, F&L GoR]

Relieve the pressure up at the manifold before you get under the car to change the filter.

In fact, do anything you can to protect your eyes when underneath- there is no good way not to get wet with fuel.

Read up on how the fuel filter ends disconnect from the fuel line.

Thanks Tom, yeah, its a fun job for sure!! I am hoping the filter will fix the problem, but I am not holding my breath. If its the pump, I am wondering if it is still under any warranty, hmmmm

All right, before I start the tank removal, just wondering if my low fuel pressure could be the MSD BAP? Any way to test it? I would hate to remove the tank and replace the pump, only to find out it was not needed.

Also, any tips on tank removal?
