Lastly, the Russian came over to help me drill the motor mount. He tried doing some crazy things I thought would ruin all my hard work. But in the end, he was right and it turned out perfect!


Now after I get a few more rivets in the fuse I'll be able to use my new harbor freight rotisserie!

Any good tips to pass on from the crazy Russian?

When we set up to use the engine mount as a guide we discovered the mount was slightly smaller than all 4 pre-punched holes in the firewall. this meant we would have to cheat to the inside corner of all 4 holes. Drilling the engine mount is through a sandwich of material. You have stainless steel, aluminum and steel weldment. The stainless tries to guide the bit toward the center despite our attempts to cheat towards the inside corner. The Russian insisted we start with a step drill and keep the drill at a higher speed than what I had learned about cutting steel. I thought for sure he would ruin the project if not dull the bit like a butter knife.

I confiscated the drill and was going to show him the correct speed but quickly learned he was right. Slow speed on that stainless just allowed the bit to bite too hard and chew the metal. I immediately granted him drill privileges again and he showed me something else. The step drill allows you to put pressure in a certain direction. Thus cheating towards our desired corner as we went along. A conventional bit wouldn't allow this... After we got the hole bored out to 3/8 into the stainless, we switch over to the conventional bit while using the engine mount as a guide.

These four holes cost me a pulled pork sandwich, beans, corn, fresh tomatoes and mozzarella, and even a "to-go" box but the holes are perfect and I fear without the Russian's expertise I would have had a big mess on my hands. Hats off to Vlad.

Hey TK,

Your install looks great.

I have the same fuel pump as you. I also used the same filter. I had read on VAF about the slip on fittings that simply use a rubber seal was not up to aviation safety standards. I kinda justified that it would be fine and built on. My engine began running rough and not idling without the fuel pump on.

20 hrs of flying and the filter was spraying fuel inside my enclosed pump area. I was shutting off using the selector valve so when inspecting my fuel system I couldn't find a leak or issue. I figured it was vapor issue regarding the 95 degree days.

After a troubleshooting run up I shut it down using the mixture. I went home to research vapor issues.

The next morning I had a tumor just in front of my left main gear leg (tail dragger). I have a vinyl wrapped aircraft and the fuel had desolved the adhesive under the vinyl leaving the actual vinyl intact creating a fuel pocket/bubble.

Opening up my enclosed pump area showed a clear dripping and blued avgas potentially fatal issue.

I replaced with the screw tight racing filter from a local shop $26 and problem solved.

Just wanted to pass on my experience. I not knocking anyone's product. The pump is great. The filter is the weak spot as far as I'm concerned. The price of the system makes it very easy to simply replace the filter.

Regards,

Scott

May I suggest that if you want the best in vibration absorption, you use a rubber washer under the bolt head/washer in addition to the one under the pump.

And, I would safety wire the bolts.

Default EFII filter

There were some filters where the rubber seal did not tighten down as much as we would like. We resized the mating parts. The current parts all tighten to a rock solid connection.

If anyone ever has any issues with any of our parts, we will replace or correct the situation immediately.
