I just got it on the road in July and working out the little bugs you always have with a new motor. Everything works great except for intermittent fuel problem. I have a new Jegs mechanical fuel pump 110gph . Fresh 454 just back from Cope Bros.Racing . Curious to here how you get your fuel issues resolved .
I have replaced everything but the tank. ( New vented Stant locking cap,sending unit, 3/8 aluminum fuel line from tank to fuel pump.all new 3/8 rubber hoses. )
I had one of those Mr.Gasket clear view in line filters, it worked great. I couldn't see much in the way of debris . I did notice bubbles would appear in the filter every so often . I talked to some of the local speed shop guys about the bubbles, they said it was normal to see a little of that. I have just replaced the Mr.Gasket clear view in line with a billet alum. Edelbrock in line . I was told by the local Total Performance shop the glass filters cost him a fire ... not worth the risk.
Before firing it up I filled the tank with New Gas ( 92 octane ). I have only run about 4-5 gallons thru the new motor , have been ramp trucked home once .
Embarrassing !!
I am going to install another fuel pump tomorrow. This time just a stock Big Block factory fuel pump and see if its not the Jegs Pump. I talked to one of the local mechanics and his buddy had a problem with his Jegs pump on his boat , they replaced it with another Jegs and it was a bad pump .. Who knows .

I would think bubbles in the filter before the pump would indicate an air leak. Have you checked all your connections to make sure it isn't pulling air somewhere?
