According to the manual, the next fuel drain line to tackle is the engine driven mechanical fuel pump. I looked and looked by couldn’t find the fitting though. I checked every book and manual I had but none showed exactly where it was. Because the fuel pump is located on the front of the engine, it’s between the engine and the firewall. I climbed all over the engine with flashlights and mirrors trying to get a better view but couldn’t find anything.<\/p>\n

Then I took my phone and started shoving it anywhere it would fit (on the engine, thank you very much) and just kept taking pictures. That’s when I found it. On the bottom of the pump, right up against the engine and behind the fuel supply line fitting.<\/p>\n

Now the problem is trying to get a line on the drain fitting. There was simply no way to get to fit. So I removed the supply line and I could almost get to it. Then I rotated the fuel supply fitting about an 1\/8th of a turn and I was able to get the drain line on. But…<\/p>\n

I had to rotate the supply fitting counter-clockwise. Loosening it. A definite no-no. Which means the fitting had to come out and get cleaned with a fresh layer of fuel fitting seal and then reinstalled.<\/p>\n

So I started to unscrew the fitting. After 2 turns, it hit the oil pump housing.<\/p>\n

The only way to remove the fitting is to remove the fuel pump. The infamous domino effect.<\/p>\n

So off comes the fuel pump.<\/p>\n

Here’s the pump on the bench. It’s upside down so this is looking at the bottom. Notice how the drain line is pointing directly at the supply line fitting.<\/p>\n

And because the pump was removed, I have to replace the gasket so I had to order one of those from my A&P.<\/p>\n

Once I got the new gasket, I reinstalled the supply fitting making sure it allowed a path for the drain line. Then reinstalled the pump and connected the supply line and feed line.<\/p>\n
