Leaky Fuel Lines

Pic 1: The source of the fuel leak

Just discovered my fuel lines are leaking! It was pretty bad to the point it's continuously dripping fuel from the lines joining the Tomei Fuel Regulator. I wouldn't have know if I did not pop open the hood the other day to try on fitment of a new part that I have just procured. What part is this? Well, let's leave that for the next entry shall we?

Anyway, back to the topic, fuel leaks are seriously dangerous! Thankfully that the ER34's exhaust manifold is on the other side of the engine. If it's right underneath the leak, the ER34 would have went up in flames! Yikes!

Just got all the lines replaced with better quality items and hopefully, it'll last me for many more years to come. What went in is Unigawa Fuel Hoses featuring an external heat resistant textile yam which sort of looked like the weaves of carbon fibre. It has an internal diameter of 8mm and an outer diameter of 14mm. The lines are designed to handle working pressure of up to 10 bar/15psi thus it should be mighty sufficient for the job at hand.

  1. Don't take the risk. Get a proper braided hose and AN fittings. Its quite expensive, but its worth it.

  2. Yes. They now have been changed to steel braided lines.
