An engine-pressurized prestart oiler for an engine having pressure lubrication is provided, which rapidly lubricates critical engine bearing surfaces prior to the starting sequence. An accumulator for storing oil and pressurized air contains an air-oil separation float, which essentially fills the internal cross-sectional area and prevents absorption of the air. Discharge and recharge of the accumulator is preferably implemented by a normally closed solenoid valve. Discharge is controlled either manually by a switch or automatically by circuitry containing ignition-off time and accumulator pressure comparators, a starter interrupter, and a prestart oiling timer. Recharge is automatic, as the solenoid valve allows oil flow whenever the engine oil pressure sufficiently exceeds the accumulator pressure. A conduit connects the accumulator, solenoid valve, and engine, connecting to the engine either at the oil pressure sensor port or through an adaptor installed between the oil filter and the oil filter mount.

An apparatus for sensing a fluid level that, in one embodiment, is adapted to fit the threads of a fill pipe or vent cap in a storage tank. A first (or upper) part of the assembly is secured in an upper portion of the tank (such as is provided at a threaded vent opening) and includes components to permit sensing pressure at a first location. A second (lower) portion of the assembly sensing pressure at a second location is disposed in a weighted casing. The second portion is coupled to the first portion through a cable that carries a section of tubing. Circuitry disposed in the second portion receives a pressure indication from the upper portion through the tubing, and detects a fluid pressure at both the upper and lower portion of the tank. The difference between the two pressures is indicative of fluid level. This level is then sent back up to the electronics assembly in the first (upper) portion. The electronics assembly can contain a microprocessor and a radio transmitter, such as a cellular or other wireless data network transmitter, to report the fluid level to a remote station such as operated by a fuel supplier. In more particular aspects, the reports of fluid levels can be delayed until periods of significantly less change in fluid level or an indication that use of the tank as stopped, to save battery life.
