Looking for a couple part numbers

Hi All. I am in the process of doing my annual and I wanted to change a few parts. The aren't necessarily bad but I feel like I want to get them ordered and changed before they fail due to age. Looking for the following:
1. Flex lines from hard line to brake caliper.
2. Hard lines from primer to engine
3. Hard line or flexible replacement from engine to OP gauge
4. Fuel flex line from carb
Any help you could provide would be great. TIA
Joe

See pages 86-88 in the parts manual - some lines vary by year. That said all these lines are typically made up in the field, and many brake systems have rigid lines all the way to the calipers. If you have flex lines, you can get new ones made either in the field or from one of the vendors by giving them the length and the fitting size.
Not terribly helpful, I know, BUT, I did look up some time ago the flexible line alternative for the oil pressure - purportedly the C150 flexible line will work and has the correct tiny (1/8) fittings for the C120s. My notes say it is a 359-2D0150. Although I just made a new copper line, your message prompted me to order the rubber one - only 7 left now!!

I have a C-140A and have a leak in the hard line from the top of the landing gear to the flexible line at the cylinder. Is it possible to remove that line without removing the landing gear leg?

In the C120/C140 I'd say you can remove the left hard line certainly without removing the gear. The right side has more convoluted line paths in the fuselage and I'd tip to the side of you might have to pull the gear. Pull the interior and see if you can get to the nut and/or remove the line once it's loose.

No problem Gene. You'll need to remove the interior upholstery next to the seat cushion below the door in order to get at the fitting to change out the line. Recommend that you pump the fluid out of the brake reservoir on the side that has the leaking line before you remove it. Also make sure you use plenty of rags to keep any drips of fluid from going down into the belly of the aircraft. Replacement tubing is 5052-0 aluminum which is stronger for hydraulic applications such as brake lines over that of 3003-0.
