Great point! Using stainless steel clamps can help prevent rust and ensure a more secure fit over time.

Common pitfalls include using the wrong size hose or not cutting it cleanly. Make sure to measure before buying and use a sharp knife for a clean cut to prevent any leaks.

Before doing any work, ensure the engine is cool to avoid burns. Safety is crucial, especially when working on fuel systems.

So true! I once made that mistake, and let’s just say, it was a learning experience! Safety first!

If you’re having trouble, consider consulting a repair manual for your specific model. It might provide valuable insights that can help!

Good idea! And don’t hesitate to ask for help if you’re still stuck. Sometimes a second set of eyes makes all the difference.

A question for everyone: what’s the best material type for these hoses? I’ve heard rubber, silicone, and even braided options discussed.

Rubber is standard, but silicone is typically more durable, especially in high heat. Just ensure it’s compatible with your fuel system.

If a vacuum leak occurs, you might experience rough idling or erratic engine performance. Keep an eye out for those symptoms after making changes.

You might want to consider an aftermarket adjustable fuel pressure regulator. It can really help fine-tune your fuel system for better performance.

A good option is the Aeromotive regulator. It’s known for reliability and performance. Does anyone here have experience with it?

I’ve been using it for a year now and it drastically improved my throttle response. Highly recommend it!

Have you thought about upgrading the vacuum line itself? Sometimes a larger diameter can make a difference in pressure response.

That’s a great point! I’ve read that the stock lines can be restrictive. What’s a good material to use for upgrades?
