Solving the Oil Line Puzzle: A Guide for Softail Enthusiasts



If you've recently found yourself in a situation similar to T-Bone in Pontiac, Michigan, who had to install an S&S Super Sidewinder and update his starter and primary on his 1988 Softail, you're probably wondering, "How can I tell which oil line goes where?" Well, you're not alone, and I'm here to shed some light on this common motorcycle maintenance query.

T-Bone's predicament is a familiar one for many motorcycle enthusiasts. Upgrading your Softail can lead to various challenges, but understanding your oil lines is crucial for a smooth ride. Let's dive into the world of oil lines and how to ensure they're properly connected.


Understanding Oil Tanks

First and foremost, it's essential to recognize that not all oil tanks are created equally. Different models and setups have varying configurations, which can make identifying the oil lines a bit tricky. To get started, here's a step-by-step guide to help you determine which oil line goes where without relying on a manufacturer's instruction sheet.


  1. Inspect Your Oil Tank: Begin by looking into your oil tank. This is where the magic happens. It's essential to understand the components inside it.

  2. Use a Coat Hanger: If you don't have a manufacturer's instruction sheet, a coat hanger can be your best friend. Carefully insert the coat hanger into the holes in the oil tank. We'll be looking for standpipes.

  3. Identify the Vent: The oil hole with the tallest standpipe is the vent. Remember, this vent is the oil line coming from the engine case, not the oil pump. It's responsible for releasing excess pressure and maintaining proper oil circulation.

  4. Spot the Return Line: If your oil tank has a shorter standpipe, that's your return line. This line comes from your oil filter and returns oil back into the tank after it's been used in the engine.

  5. Equal Standpipes: In some cases, you might have an oil tank with two equally tall standpipes. In this scenario, it doesn't matter which is the return and which is the vent. They serve the same purpose.

  6. Single Standpipe: If your oil tank has only one standpipe, it's important to note that the return and feed lines can interchange. However, the feed line should be the one at the lowest point on the oil tank. You can identify the feed line by checking the right side of the oil pump as you look at it.

Here's a simple diagram for a stock-style oil tank to help clarify things:
