1990 V3500 454 "3+3" 4WD
I recentley returned from a deployment and found my truck no longer ran. Turns out the issue was the inside of my driver side fuel tank rusted bad and the corrosion spread all the way up to the injectors. The fuel pump and injectors were overed in white corrosion and there was little bits of whatI assumed to be rubber from a section of rubber eaten away by the gasoline on the fuel pump assembly. I ordered a replacement fuel tank and fuel pump assembly and rebuilt the TBI (with new injectors). Before I install the new tank I am wondering if I should replace the fuel lines with steel braided PFTE line or am I in the clear to just clean out the lines. The feed line at the block shows light orange rust around the flange and the return line shows light, possibly carbon, residue. Otherwise the steel lines look to be in great shape. Can I just spray out the lines with carb cleaner and an air compressor? Or should I go ahead and replace the lines to prevent damage to injectors? Any feeb back is much appreciated. Thanks yall.
