BTW - It is normal for the fuel pressure to drop to 0 within about 10-15 minutes from shutdown. Mine drops from 38psi to 0 within 15 min of shutdown. Replacing hoses will not change that.Telram: so far I only replaced 2 rubber stainless braided aftermarket lines that was old, sof ar the 2 I repalced doesn't appear to smell, only the remaining one. I'm doing the remaining one this winter, I hope the smell stop and fuel pressure stay between shutdown and startup.
Also PTFE braided lines offer less resistance to fuel than traditionnal rubber lines, fuel flow more in ptfe lines... I used -6AN
