Don't discount this as just an inline fuel filter. Far better than most. This filter features metal ends and a one way flow check valve. Ideal for applications where fuel drain back is to be prevented. This pre-filter will catch larger particles allowing the downstream filter to do its job. Fits 3/8" or 10mm fuel lines, hose clamps included. The unit is serviceable and we offer replacement filters for it.
The 5/16" model is recommend for post-injection pump return lines, where pump condition and fuel quality can be monitored post-filter. If you have an Algae problem, highly diluted rust or water and other visible contaminants, this is handy window into the insides of your fuel system.
