Re: Adhesive/Epoxy that won't dissolve in gasoline?

Hi there,
 Curious if anyone can recommend an epoxy/adhesive that will both adhere to
HDPE plastic and not dissolve in gasoline? A bit of backstory..
 Shortly after purchasing a used car I planned to subject to winter duty,
the plastic gas tank wiggled itself loose and made contact with the
spinning driveshaft, wearing a nice elongated hole in the tank. With no
nearby replacement available, I went down the rabbit hole of plastic
welding HDPE tanks, and successfully closed that hole. With this fix
replacement tank straps were acquired, and the risk of a shifting tank was
abated. 20,000+ miles and a year later, the plastic weld is letting go,
and gas is leaking again.. I can hardly be annoyed that the weld held on
for as long as it did, but I opted for a hopefully permanent fix this
time.
 I picked up a replacement tank, but upon delivery, I found the tray that
the pump sits in had broken free from the tank itself. The yellow tray
seen in this picture: https://i.imgur.com/x9bCPWym.jpg
 It appears to have originally been glued in placed, judging by this

 I really don't like the idea of this tray sloshing around in the tank,
potentially knocking off the pickup sock at the worst time, so I'm looking
for recommendations of adhesive that can stand to survive being submerged
in gasoline permanently. I've found a few options, such as LOCTITE 1252795
and Seal-All, but figured I'd ask to see if anyone recommends something
else.
 What would you use to secure the tray in this situation?

Not only will the glue need to withstand gasoline but also Ethanol and water.  About 50% of the gas stations in the USA use double wall FRP pipe and the pipe joints are epoxy glued with epoxy made for that.  The other 50% use double wall HDPE but they are not glued.  They are either hot welded or clamped.  I don't know of any glue that will adhere to HDPE.  BTW, the photos don't work.
