Header tank fuel strainer!

[astjp2]

Here are a few pics of a properly repaired fuel strainer with a valve installed. The elbow starts out as a 3/8" Male NPT and goes to 1/4" female NPT in a 65 HP aircraft, the 85 HP are 3/8" on both ends. Tim

More pics, with the right tools, a mechanic can build anything!

Awesome, thanks for sharing, Tim.

Re: Header tank fuel strainer!

Yes, nice job Tim!

You encouraged me.

I think that I am going to make some too for my Aeronca wing tanks.

They never had any and I think it is good to have them.

The tanks have 1/4" pipe threads so the strainers must be made none are available for purchase.

I can build you what you need, just PM me a pic or hand drawing. Tim

Re: Header tank fuel strainer!

Tim can you give me the critical measurement for the 1/4 or 3/8 pipe you mentioned for the valve? Like OD of the critical fitting flats so I can tell what I have? I can also take a pic today and will post that so you can see what it is. I assume with the Harer C-85 STC it would have the larger lines.

Re: Header tank fuel strainer!

The bung on the tank is 3/8", then it is necked down to 1/4, the fuel line going to the valve is 3/8, the valve is a 3/8" but installed wrong. Does the system penetrate through the firewall straight out from the valve? Look at the first series of pics I posted for a correct installation, should be 1 elbow and the valve going straight out the firewall with a fitting to install the line in the engine compartment. You have a lot of places to get a leak. If it works, no big deal, if you have fuel smell or have to have original, then you may want to change the installation. Tim

Re: Header tank fuel strainer!

No leaks. I see where the valve arm is on the other side of the valve than yours (?). Maybe person or persons unknown did it for some fitting reason. I'll take another pic of the fuel line today. The line assembly makes a 90* turn to the left looking forward at the firewall downstream of the valve, goes a distance parallel to the firewall, then passes through a bulkhead fitting to Steve's gascolator and on to the carb. Seems to work and shut off fuel.

According to paperwork the tank was removed, cleaned/inspected/repaired by Atlee and a F-19 fuel gauge installed aft of the windshield I assume per the Harer SA-210 STC to limit the "E" empty fuel gauge reading to 3 gallons (it does as expected). The fuel valve may have been rigged at that time but may also been done when Steve's filter was later installed versus the factory setup via Steve's STC SA01026SE. I assume their goal was to get the gascolator away from the bottom of the cowl to minimize damage in an airframe upset.

Will do, I also have some material I purchased, will send them too.

Re: Header tank fuel strainer!

The gascolator mounts on the engine mount via a tab in the lower pilots side, line passes through the center of the firewall below the tank, then around the back of the engine to the lower right side of the mount...where a hose then comes out of the gascolator and goes to the carb.

Re: Header tank fuel strainer!

Mine exits the shutoff valve as shown above and goes through the firewall with a bulkhead fitting directly into Steve's gascolator, then on to the carb. The original center hole is occupied with carb throttle and tach cabling fed through a fire grommet. The Mother of Invention must have done it previously. Works and flys ok.

I was asked to make a few screens for a member, came out nice. Tim
