Mechanical Fuel Pumps

[jocko]

Have had two old pumps work great on two different trucks UNTIL I parked them. Then both went bad in about 6 months. . It' not the brand of pump or the ethanol content (and the non-ethanol type is NOT available everywhere) it's whether they sit around and dry out. That doesn't mean that it will happen, it just means you increase your chances of it happening if you park it for awhile, regardless of pump type or fuel. A couple data points on a given mfgr of pump doesn't mean it won't fail when allowed to dry up.
