Re: ls fuel pumps problem
Yes it is a aluminum fuel tank This had been a on going build [many years] of sitting due to other obligations I did have a new vent installed years ago and overlooked a good cleaning when the time came for start up, and only had a small filter on it. Costly mistake

Re: ls fuel pumps problem
I'm running a big Aeromotive in-tank pump, but I run a 100 micro pre-filter and a 10-micro post-filter. Protects the pump from large chunks like that.
For a more conventional style pump, you'd think the "sock" would catch that kind of stuff...
