Thought I'd post this in case anyone else has suffered similar issues. My rocket has been tempremental starting after short runs. I have now traced this back to the small o rings that surround the nipples that go in and out of the fuel pump. The originals had perished and must have been letting air in. I've replaced the o rings and the rocket now starts first time very time..  |

Interesting to know..! Had an issue a few years back with foam filled tanks and seals being eaten away by higher octane fuels.
It probably lost residual fuel pressure as it syphoned back to the tank through the broken seal.
I bet after a few primes it was ok?

Correct, that was what led me to look at the o rings...
