fuel line issues ? 1996 gtx

[walt318]

Half throttle losing power intermittently, Took out fuel selector valve and tried in all positions, by blowing compressed air through the valve, don't feel there is any blockage, Did not remove fuel lines for inspection, to rule out for fuel lines breaking down internally, Any input appreciated

Replace gray fuel lines, rebuild carbs and needles and seats, replace fuel strainer and selector. Only OEM parts.

Decided to remove all the fuel lines and filter and selector valve, used compressed air to blow through fuel lines, did find a restriction with the lines, used compressed air to blow through filter housing, no restriction found there, tried blowing compressed air though selector valve and output of air was lower, much lower than air that was going into the valve on either the on or reserve positions, took the valve apart and found the internal housing of valve has a rubber bushing that was all deteriorated, replaced valve and back to full power in the WFO position. Thats the FIX
