Factory is steel line down the left frame then crossing over forward of the engine. Short rubber line ( must now be barrier rubber line due to E10) to mechanical pump front right. All steel line up to carb. Hard to say exactly what mods your system has. The proven solution is a low pressure elec pump in front of left forward wheel as close as practical to the selector valve. The AUX switch wire feeds the valve and is 12V only in AUX. T off that wire to a weatherproof relay for signal source. Feed the 12V actual power from ign switched point on fuse box. When you switch to AUX on the dash the pump comes on and VP clears in under 2 sec. There have been tons of theorys and failed attemps at fixing VL but this one works. Remember old style rubber fuel line is obsolete due to E10. It breaks down in a few short years snd starts weeping fuel. All hoses should be type such as Gates Barrier by now or you have a fire hazzard.
