There isn't a universally standardized diagram, but you can easily represent it visually. Here's how you can visualize it:
Method 1: Numbering the spark plugs:
Imagine the engine from the front (radiator side). Number the spark plugs 1-8 sequentially, starting from the front passenger side, then going to the rear passenger side, then the rear driver's side, and finally the front driver's side. Then apply the firing order above to that numbering.
Method 2: Using a Diagram:
While a precise diagram would require a picture of the engine itself, you can create a simple textual representation:
```
1 5
/ \ / \
2---4 6---8
\ / \ /
3 7
```
This layout is a simplified representation and doesn't show the physical arrangement perfectly, but it helps visualize the sequence. Remember the numbers correspond to the firing order (1-5-4-2-6-3-7-8).
Important Note: Always double-check your specific engine's markings before performing any maintenance or adjustments. The firing order might vary slightly depending on minor engine variations for that year, though it's highly unlikely with the 351W. Your owner's manual (if you have one) will have the definitive answer.
