An injector line started leaking on the 7050. Hard to tell where from or even if I had the right line, #4. The rest were dry except #3 and #4 but #4 had drips coming off it. The return lines are dry. Leak seems to be behind the exhaust manifold or running down from the injector. I put #4 under water with air pressure and no bubbles. Tried #3 too and no bubbles. Can it be that 50 psi of air won't show a leak? #3 was only slightly wet with fuel but I figured the way the air was swirling it got wet from #4. The fittings at the injector were tight. It has the Allis injectors. What are the experiences out there. Thanks.

I have seen the line crack right next to the ermeto sleeve(ferrule). Should be able to find a good used line. Probably still available new, but pricey(over $100 each). good luck. Ed.
