So... I have blown a high pressure fuel line three times since I put in this 1.9L NA running the 1.6L pump. Once three years ago: newer steel one #2 cylinder. Once two months ago: The old stock used one that I put in to replace the first one that blew on #2 cylinder. The one I bought from MK1autohaus two months ago, just blew. The last two times it was just a pin hole. This time the line is completely severed.
Should I be looking for a higher quality part or could this be an underlying problem developing with my pump? too much pressure in #2?
