Pethia,
If you convert to an electric pump, make a blanking plate for the old mechanical pump. Remove the mech pump and run the hose directly to the filter housing. The mechanical pump has check valves and a rubber diaphram that can fail anyway. If the diaphram fails, your crank case fills with diesel and you can get a runaway engine. A new lift pump is only about $65.00 and will last 10+ yearsPat McCartinInland Marine DieselBuford, GA
