Autogas Fleet Service
The 5-micron inline filter is the one part on a propane conversion that protects every other part. Keep it on schedule, and bring the used one back for credit.
Filter Exchange Credit
Bring your used filter housing or element to Heine Propane and receive an exchange credit toward the replacement element or a new filter assembly. One credit per filter exchanged.
Liquid-injected propane engines in delivery trucks, pickups, buses, and vans draw fuel straight from the tank. Rust, scale, and sediment that settle in the tank and fuel lines travel with it. The inline 5-micron filter stops that debris before it reaches the injectors and the vaporizer, which are the most expensive parts on the system.
A clogged filter shows up as hard starts on propane, hesitation under load, lost power, or the system quietly switching back to gasoline. A fresh element costs a fraction of an injector set.
Heine Propane services the filters on the conversions we install and on most liquid-injection systems from other installers. We stock replacement elements and complete housings, and we can rebuild your existing housing while you wait.
Severe duty (dusty routes, older tanks, high idle hours) shortens the interval. Ask us to set a per-unit schedule for your fleet.

No. The housing is rebuildable. In most cases we replace the pleated element and the Buna-N seals and reuse your anodized aluminum housing. A new assembly is only needed if the housing or fittings are damaged.
Yes. The credit applies to any used liquid propane filter you bring in, as long as we are supplying the replacement. Bring the housing so we can match ports and fittings.
The filters we supply carry a 350 PSIG working pressure and a 500 PSIG test pressure, which meets the 350 PSIG design requirement for liquid propane engine fuel systems under NFPA 58. The housing carries etched certification markings.
We depressurize it, pull the element, and recycle the aluminum housing or rebuild it for the next exchange. That is what the credit pays for.
