Disolving fuel pump strainer

[elgoathead]

This and the ferule attached to the pump base were all that remained of the fuel pump strainer. There were no other fragments in the tank. It's as if it dissolved in the fuel. I've never before seen such a thing.

I blame the ethanol commonly added to today's fuel. What do you think?

when i changed my fuel pump at 180k my strainer looked fine other than being dirty/discolored. perhaps it yours was dissolved by overuse of fuel additives (fuel injector/fuel system cleaners)?

aftermarket screen?

I agree that's an extreme example of screen deterioration. Are you the original owner or did you purchase your vehicle from a previous owner? I suspect the screen is an aftermarket ebay item from China. I used to avoid ethanol added fuel but now that's very hard to do. I have to drive 20 minutes out of my way to purchase ethanol free 93 octane gasoline. Ethanol is a prime example of inept government meddling. I've read that ethanol will dissolve gaskets unless they were designed for it. Ethanol provides less power than gasoline although I think it does have a higher octane rating. Below is a photo of my original 2000 fuel pump assembly after 160K miles.

It had 120k miles on it when I got it. The pump appeared to be original so I'm assuming the strainer was as well.

I don't use fuel additives but the previous owners may very well have.

I'm a fan of ethanol free gasoline as well, but only buy it if I happen to need fuel when I'm in the next town over where it is available.

Thanks for the responses!

Ethanol is highly corrosive. That strainer does not surprise me at all..
