Fuel connectors, and heater hose connector questions
Per a separate thread, I am putting 2001 Park Avenue 3.8L back together following intake manifold replacement, etc, so I will recap success when completed in the other thread. But meanwhile I have encountered a few concerns in the assembly.
Fuel rail connectors:
Fuel rail connectors are now leaking. Fuel system not pressured up yet, but daytime heat is expanding fuel in lines and the original connectors at the rail are now leaky. The 3/8" rear connector is dribbling badly and the 5/16" front connector is staying damp.
Per a search on this site I found several owners have had specialty connectors adapted for use. A few have mentioned Dorman part 800059 available at several sources, but this is for the 3/8" line only. Have not yet found any listing for a 5/16" size. Are these Dorman connectors holding up?
Since the search threads are getting dated, is there any newer suggestions for replacement connectors for both size lines? I can buy online or pickup local if Advance or Autozone can obtain, but first contact locally found no info unless I can supply a manufacture and part number. Not too keen on driving to a distant Buick dealer nor grabbing the JB Weld.
Heater hose connectors at the tensioner:
When taking this apart, the oring seal hose adapters were set in place from heat and time. In putting this back together I now see the small retaining bolts have a thick shoulder and do not really tighten down against the ear, so only the orings provide seal -- the hose is free to wiggle about until time and heat prevent movement. Question is whether there were ever a grommet/spacer taking up the slack to hold it tighter in place?
Appreciate any tips you can send my way on these concerns. I am trying to get this project wound up, but many other things have dragged this out for longer than expected.
