Well as you know Ive been struggling to get project daytona running well... I finally got it running great only to give a cough and splutter and stop... having gone through it all again I found it was the fuel pressure relief valve which had bust... so the replacement is fitted and it now runs sweet and ticks over! As you can see from the picture the one I took out, the top does not sit flat above the o ring unlike the new one.
Excellent, glad you found a fix and this will help any of us fellow Daytona owners if we see the same issue. Cheers Geoff
