First post!  Did the search and couldn't find the answer.  I have a slow fuel leak around the rubber fuel heater seal on top of fuel filter canister.  Can I seal it with something or just yank it out and replace it?  No diagram in my Haynes manual.  Developed same time my raptor pump jumped up about 5 psi.  I adjusted it back, but the leak has not slowed.  Any suggestions?  Thanks in advance.

When you remove the canister can you see if the seal is torn or dirty?  Is it leaking from the nut that tightens the canister?

 

Also, you said when your fuel pressure jumped to 5 psi?  You should maintain at least 14 psi of fuel pressure.  If your left pump is only getting you up to 5 psi you ought to look into that.

I haven't taken the canister apart since I did the filter change about 500 miles ago.  I inspected thoroughly and there were no issues or leaks until three days ago.

 

I keep the fuel pressure at 13 psi but it jumpeed to 18 when the leak started.

 

Just found out on 98.5 to 99s this is a common leak.  Its right around where the fuel heater goes in (on top of filter on 99).

 

Thanks for the quick reply.  The video below I think has the answer.
