Re: Oil pressure line restrictor
This hose just burned me. I was lucky it was only a 10 minute flight because in 10 minutes I lost all 6 quarts of oil. Had oil pressure until I shutdown and when I got out there was oil pouring out of the cowl. This hose had broken. I just purchased my first tri pacer so this hose was news to me. PHEW

Hi,
....This hose just burned me.
Wait until you find out what Univair wants for a new one, you'll feel burned again.

Hi again,

How do you know you had pressure, that restricted line goes to the guage? You are writing about that 6 or so inch long piece between the engine and the mount area, yes?

Re: Oil pressure line restrictor
Soooooooooo Why can't you make up a new 303 hose with old fittings for about $5.00?????? If it is the hose from the eng. to the firewall.

Re: Oil pressure line restrictor
Because the guage showed it. After I shut down it was still blowing out for a minute....

Hi again,
....Because the guage showed it....
Lucky you! Mine broke clean off, 50 year old rubber. My guage was at zero, I caught it during an instrument scan. No apparent damage after five minutes to make the closest airport. Nothing on the dipstick. I'm still a little uneasy about things after 30 hours since almost losing it. The engine had less than a hundred hours on a major at the time.
The other Jim asked, ....Why can't you make up a new 303 hose with old fittings for about $5.00??????
Good question. I don't remember what it looked like.

Jim,
On mine it is about a 12" piece of 1/4" 303 hose. Comes off the acc. case to a bulkhead fitting.

You can see it in this picture.

Hi Jim,

I seem to remember mine being shorter, like six or eight inches. One end fitting had a very small passage, like a sixteenth or so restricting it down. Maybe the ends are standard, I've never made an aircraft hose, just the small primer lines. Cheaper is almost always better, for me.

Re: Oil pressure line restrictor
The Piper hose is shorter. You can replace just the rubber hose on the Univair oil pressure/restrictor line. No special tools needed.
