Rubber Fuel Line Disintegrated In Tank - Next Steps

[Scooby]

Hi everyone, would really appreciate some experienced- based advice on next steps to address this problem.

Car wouldn't start and the problem was traced to fuel starvation. On removing the pump it was found that the fuel line rubber had perished so it seems the workshop that installed the 044 used fuel line that was unsuitable for an intank application. 044 mesh was clogged and once unclogged it worked fine. I haven't seen the rubber yet but I'm told it just falls to pieces and dissolves. No indications of a problem until it refused to start recently.

Plans are to:

Clean tank

Clean injectors (maybe overkill?)

Flush everything from the fuel rail back

Replace filter

Replace pump (with a Walbro)

Any thoughts on other things to do?

Just flush tank, change fuel filter (maybe every tank just to be safe, they're cheap enough), change pump, and use proper submersible fuel hose.

Also that shop, or whoever did it - should be shot.

Get a Walbro 450.. they're good pumps, quiet, work well, flow well.. if used in a very basic/stock application the OEM wiring is ok... start to up the boost make sure you run a proper 60amp relay fed directly the battery through a 25amp fuse.

+ make sure you install a dose pipe, and tune it.. more bends & more length more dose

I am truly disappoint! Where is the recommendation for dose pipe install.

You've changed man.

Definitely agree with point 2 although that could be too good for them. The guys who found it were only second to me in being pissed off.

We've got a 450 lined up, and the direct feed/fuse and relay have been installed but not sure about what to do about the stock loom between the relay and tank lid. The Fuel Pump thread had some discussion on the wiring between the relay and the plug in the tank lid but I couldn't see where anyone had come up with a solution yet. I was thinking about running a heavier gauge feed between relay and tank lid plug, and then from the underside of the plug/lid to the pump on the assumption that the plug pins could take it.

Dose pipe checked when car refused to start, all ok

Might as well just put it in your sig.

I am currently having issues with getting power through the fuel tank lid to a Walbro 450, all started after the wires inside the tank shorted. Have tried two lids and can't get power through reliably, am now guessing the plugs on top and/or bottom of the lid are fubar.

Now considering ditching the factory wiring plugs and putting two bolts straight through the lid, sealed of course, with eye connectors on top and bottom.

Might move these q's over to the fuel pump thread
