Glad to hear. Thanks for the post Alfio.

Another happy customer,

Installed them last week on the IO-540, easy to do with the help of a 1/4"dve 7/16" Snap-On Uni socket to get the the inside clamp bolts.

As others have reported, install the New SDS collar with the bolts and leave a small gap to simply slip the Viton O-ring and retainer straight in . Torque up the bolts and you are done.

All of my Lycoming retainers were warped and the gaskets were loose in the middle, this engine is only 525hrs SMOH.

Thanks Ross, a great upgrade !



Out with old, in with the new !!

I am glad to here so many people are finding tangible running differences with our setup. Can enjoy flying their RVs more and avoid the frequent gasket changes.

Once I can locate a reliable clamp supplier for the carbed engines, we can get more kits going out the door again. Another batch will be going to anodizing on Monday.

Thanks for the review Ashley.

Found another benefit to these things yesterday. I needed safety the lower baffles and one of the induction tubes was in the way. I tried several times to get a good angle on the problem and then the light bulb went off - just remove the tube! In less than a minute the tube was on the floor and I had access.

In the "old days" we knew tube removal meant some time scraping the remains of the old gasket off the head and then hoping you had a new one around. Not so now.

Default Clint at Vetterman

On my first set, I tig welded the ends and it looked ok but the angle wasn't perfect. So, I found a set of tuned induction tubes for my "forward -facing-angle-valve-converted-parallel-valve lycoming, and hired Clint at Vetterman to weld them up for me on his jig. Guess what? The welds are beautiful and the alignment is perfect. So, if your welding skills are a little rusty or if you dont have an alignment jig, Clint is the man.

Does that affect the sealing of the big doughnut seal where the pipe fits into the sump?

I'm guessing the sealing surface in the sump is long enough, (deep enough) that being a little bit shorter doesn't affect the seal? If it is just sealing in a cylindrical bore, that is probably true. If the seal relies on some compression from bottoming in the bore, then the shortened tube would not produce as much seal compression.

Many of you have been on a list to receive induction flange kits for almost 3 months while we were waiting for our suppliers to ship black silicone hose and constant tension clamps.

We got the hose a few days ago for the injected engines and clamps as well and have been filling back orders for injected engines the last few days. Those are available now.

Unfortunately we received the wrong CS clamps from our supplier in Germany for the carbed engines which use a larger OD hose and still can't fill those orders unless people want to re-use their original screw type clamps.

I'm not happy with the situation after waiting nearly 80 days for these clamps. Trying to find a solution with the supplier today but it could be another long wait as they probably don't have stock and will have to be produced.

I've checked 4 other suppliers/ manufacturers and nobody has any inventory.

Ross,
Do you have the o-ring specs? I need to get a couple of spares.
Thanks,

They are #135, 70-75 durometer. Silicone for injected engines, Viton for carbed engines.

Default O-ring source

I was able to get extra O-rings locally from Grainger. Their item # 1BYL7 - "Round #135 Medium Hard Viton O-Ring, 1.925" I.D., 2.131"O.D., 10PK" for just over $7. These are 75 durometer Viton for carbed engines.

Default Good News

After hours of searching online I finally found some bulk lengths of fuel approved, made in USA, Buna-N reinforced hose with the correct ID and OD so we can use the same clamps on carbed and injected engines now. I have a couple lengths in hand now and can start filling back orders for those on the "list" with carbed engines this weekend until we run out of flanges.

More flanges are being CNC'd this weekend as well and will be off to anodizing on Monday. Colors available will be red, gold and clear.
