Rubber pieces in FPR

[Mountain Synergy]

Pulled my FPR today and inside(looks like metal filter)--when i pulled it out of its tube there were several little pieces of black rubber in the tube and stuck to the metal filter. Wondering if rubber is from the FPR or from injector o-rings? any ideas?

I was not referring to the meatl screen, rather the wad (looks like steel wool) inside the FPR.

What type of truck is it?

[Mountain Synergy]

97 F350 . Stock, except SVO conversion. Have put over 10K on SVO so far, with no probs. However a month ago, cam pos. sensor went out, then the stock fuel lift pump, now (according to symptoms) i think it's the ICP sensor, which will be put on soon.

MountainSynergy,
What were the symptoms of the stock fuel lifter pump going out? I just did SVO on my 99 PSD 7.3 and am having issues of no power and lots of lugging. I fear I might have to replace mine as well......

Actually, my cam sensor went out first. Then, just a week later my lifter pump just quit. I noticed a little seepage on the top where the fuel line hooks up(not leaking from hose though, coming from where nipple is attached to pump). Also as a precautionary note, make sure your oil is 100% water free. What kind of pre-filtration are you doing? Does your svo run better than diesel, or the same, or vice versa?

Found out the issues.
1) bad injector on cylinder 1. Replaced
2) Bought inline electric heater for truck. installed right outside of tank.
2) 165 degree thermostat on truck. 203 degree on order. Oil was only 146 or so going to engine.
3) Oil is filtered to 1 micron and run through a separator for water.

So, cold oil and bad fuel pump (replaced) were at fault.

Can't wait to see how it runs on veggie when its HOT!
