We ran the engine today. Multiple starts and stops while making some configuration changes to the Dynon.  Very smooth and quiet engine. We are having problems with the seals around the fuel filter.  The A&P who is helping suggested that maybe banjo fittings aren’t the most appropriate for the pressurized side of the system.  Does anyone know of an appropriate sized filter with pipe fittings on both sides?   Thanks

Fred, I'm using coarse and fine filters from EFII.

You might have to reconfigure your fuel lines?

Yeah banjo fitings scare me too. I put some EZ Turn (sticky) grease from Acft Spruce on the gaskets and threads to prevent galling of the copper and aluminum and to help seal.

The filters are just what I need. Thanks

I had a problem with a fuel leak on one side of the filter also. The copper O ring was defective. Ordered a new one, and solved the problem. Ron

Here’s my solution to the banjo leaks.  Made a custom manifold and used the EFI filter.  Had to make a new line from the fuel pumps to the filter.  No leaks.

Hey everyone,

As the OEM supplier to Zenith for the conductive Teflon Fuel hoses in the UL Power firewall forward package, this issue that some are experiencing is of interest to us.

A banjo fitting should be able to withstand much higher pressures than exist in the UL power fuel system without leaking.  We build Rotax hoses with Banjos and pressure test every assembly to 2,000 PSI with no leaks.  

With that said, if anyone does decide to reconfigure any of their firewall forward setup and needs different length or configuration hoses than we provide to Zenith for the OEM hoses, please reach out to me at aircraftspecialty@gmail.com.

We have the option to either reconfigure your hoses (if possible) or build new custom hoses for you.  But, please make sure you let me know that it's for a Zenith with a ULPower firewall forward package so we can give you a discounted rate on them.

Have a great week,

Steve
