I am getting close to getting my O-200 engine overhaul complete.
As part of the process, I am replacing all 5 hoses in the engine
compartment.
Could you well informed experts help me figure out what the replacement
hoses for the following are?
HOSE 1: OIL PRESSURE
====================
Catalog shows part #415-48201-1, a 1/4 x 22 hose.
Mine is certainly different. Mine is 25 inches long and has fittings
attached. The fittings are labeled:
MS 24590-4
IFC 0007-2
I'm thinking Aeroquip 350-4-0250 would be the one to use? (Page 122 in
Aircraft Spruce 2005 catalog)
HOSE 2: FUEL LINE "SUCTION"
===========================
Normal 'Coupes use a 415-48201-2 which is a 1/4" x 40" hose.
Mine is supposed to use the same, but only needs it to be about 8 inches
long (I have the electric fuel pump right there on the firewall).
Currently installed hose is labeled "6000" which according to Aircraft
Spruce, if it is "MIL-DTL 6000", it is not recommended for fuel (see page
121 of 2005 catalog).
What is the original hose? Or better yet, what is the best to use?
HOSE 3: FUEL LINE "PRESSURE"
============================
Same as hose #2 except the part number is 415-48201-3. I don't know why it
has a different part number as it seems to be the same as hose #1. Anyhow,
again, I need about 8 inches.
HOSE 4: FUEL LINE TO CARB
=========================
Catalog shows part #415-48201-4 which it says is a 3/8 x 24 hose.
Currently installed hose says "6000" on it and is 3/8 x 21. Again, perhaps
it is "MIL-DTL 6000" and shouldn't be used for this purpose?
It is currently covered by AS1072-12 SIL FG fire sleeve. I suppose I should
replace it as well?
HOSE 5: VACUUM PUMP LINE
========================
Installed hose is unmarked. It is 29 inches long. Seems to be about 5/8"
inner and 1" outer diameter. It is plain soft black hosing.
I am interested in getting these hoses ASAP. It is all that holds me back
from getting back into the air! If you can help me identify these hoses
and/or know someone who can get them to me quickly, I'd be most indebted to
you!
