Both of these forms of dried alcohol will clog nozzles and fuel filters. TWO methods for Short Term Storage: 1) Drain Method: Totally drain the fuel tank and blow out the plumbing lines, barrel valve, nozzle lines, bypasses, fuel pump, etc. Oil the pump lightly. 2) Gasoline Method: Drain the methanol out of the fuel tank. Put in a couple of gallons of gasoline. Start and run engine (Note: engine will run poorly and very rich), changing to a much larger main bypass jet will help reduce this problem. The gasoline will mix with and flush most of the methanol out of the system. Depending on bypass valve pressure settings the gasoline may not blow through all of them. Leave gasoline in system till ready to use again. Drain out gas, put in methanol, most likely install fresh spark plugs (fouled by gasoline), and go. MAGNESIUM MANIFOLD AND PARTS Water and methanol (alky) are VERY CORROSIVE to magnesium. Take great care not to let a magnesium manifold or parts be exposed to water or liquid methanol. Examples: Where manifold intake flange contacts the water ports of the head. Letting methanol fill up in the intake runner. Setting a manifold on a concrete floor (the mois- ture on the concrete will react where the part contacts the concrete). Washing parts with water or steam cleaner and allowing the water to stay on the parts. PROPER LONG TERM STORAGE OF AN INJECTION SYSTEM Totally disassemble the fuel system, blow out all hoses, lines, tank, and manifold. PUMP: Drain all the fuel. Using motor oil, fill the inlet, rotate pump over several times, then cap. BARREL VALVE: Blow out fuel at idle and wide open throttle, then cap secondary port. Using motor oil fill the inlet, rotate spool back and forth several times, add more oil, cap off inlet. BYPASS VALVES AND FILTER: disassemble and clean. NOZZLES: remove from manifold, then blow out. Note: light spray oils may evaporate that is why we recommend motor oil. NOZZLE INSTALLATION Any time the nozzles are removed from the manifold, put some anti-seize compound (Kinsler #1920) or heavy grease on the threads before reinstalling them. This will help prevent the nozzles from becoming seized into the casting. This is especially important on manifolds using methanol or nitromethane, since these fuels setup a corrosive action between the brass or aluminum nozzle body and the magnesium or aluminum casting. Do not overtighten the nozzles: NPT thread nozzles only have to be tight enough to maintain their position and o-ring nozzles only have to be tight enough to seat the hex and crush the o-ring. MANIFOLD AND LINKAGE LUBRICATION A little oil applied to the shafts and rod ends helps keep them from sticking. Apply oil on the throttle shaft at both sides of the casting/bushing; rotate the throttle to allow the oil to penetrate. Oil the ball section of the rod ends (heim joints). Wipe off any excess. BYPASS VALVE INSTALLATION Do NOT screw jet cans directly into the fuel pump. Engine vibration can be severe enough that the poppet or jet may bounce off of it’s seat, causing the engine to run lean or erratic, especially in four cylinder engines. Installing the jet can by a hose on each end eliminates this problem; the hoses dampen the shock. Magnesium manifold runners heavily corroded by liquid methanol left in for one week. The engine broke an inlet valve rocker arm.... since the inlet valve didn’t open, the alky accumulated © 2017 Do not leave methanol in the system for more than two days, as it can be VERY CORROSIVE to aluminum parts, especially when it has some moisture in it. We offer many adapter fittings and components that are hard-anodized then impregnated with a sealer to resist corrosion by methanol. Color anodizing (usually red and blue) provides only very slight protection. METHANOL (ALCOHOL) IN THE FUEL SYSTEM AFTER RACING Do not screw jet cans directly into the fuel pump.
