Okay, so I'm thinking about this for most of work today.

I get home, super keen to try the electric pump. I attach the inlet side, and figure this is a good time to try a delivery test. Just hold the wires onto the solenoid and ground...tappa...tappa... away it goes.

I run it for a bit. Nothing. I figure the line is full of air, and the leccy pump can't pick it up, no worries, I'll push some air into the filler neck, prime it and we'll be away.

I put air into the filler neck, I hear the tank expand a little...hmmm... front is still dry

So under I go, there's a flexible bit of hose between the tank outlet and the subframe where the steel pipe had been previously cut. So I attach a long hose on there and blow....HARD.... and then suddenly I hear bubbles... I try and suck and get nothing.

So a blockage somewhere in the tank...that damn gauze filter on the inlet inside perhaps? Anyway tank is drained, next is to drop it out and see WTF is going on inside there. Can I get that dinky inlet filter off from the tank sender hole?

Bit bummed I couldn't go for a test drive...better than getting stuck though!

cheers,

Jacob

If you can't get to the tank gauze to clean it, stick a drill up it through the outlet pipe, then fit a filter on the line.
A Commodore or Falcon steel can one is good, I'd not use a glass or plastic filter under the car.

So the Goss pump might not be the cause after all?

Looks like the Goss pump might be okay indeed!

It came off the 1100S and I had only recently-ish put in new valves and a NOS diaphram, but thought that new fuel had stuffed it or one of the valves gone, but looks like not

It was definitely hard to blow into the tank and as I wrote above, I could not draw any fuel by sucking at all, so it's blocked. The steel pipe under the car was nice and clear.

Tomorrow I will drop the tank, take the petrol gauge sender out and see what is causing all my dramas, be good to get this last "new car" gremlin

cheers,

Jacob

Do you have an old speedo cable? You might be able to push it up the pickup tube to knock the blockage out of the way.

That is a damn fine idea! I only just put one on the shelves when I was tidying up on the weekend

This is pretty much what I did a month or two ago, but using an off-cut of a bicycle brake cable with the lead knob on the end (Just because it happened to be in the top of the rubbish bin in the shed from a couple of days earlier!) The knob on the end was a loose but good fit in the pipe.

I had a similar problem after the car had been sitting for about a year... couldn't get fuel out of the tank.

I had already washed the tank out and tried a number of things to 'soak out' the blockage with limited success, along the way working out that it was not the screen that was blocked, rather it was the metal line inside the tank not far along from the filter end.

I actually used a battery drill to spin the cable while working it in and out from the outlet end, eventually dislodging what looked like mud rather than rust. Very fine, not gritty at all.
After washing it all clear again with kero, the filter screen is still intact and the flow now is good for about 300HP!

It lives!

Dropped the tank, and the gauze looked beautiful, but still hardly any air would go through.

Old speedo cable revealed that...something was stuck in the tube, and as per Tim above, it was fine stuff.

A bit of mucking about with the gauze (put a hole in it), more old speedo cable, then some compressed air and thwock! Out comes the blockage and now it's breathing easy. Filter is installed before the Goss mechanical pump, and boy did it fill up fast this time

Just went for a rather sprited run, the engine sings quite sweetly at 4500 rpm (still running in, don't want to wind the t!ts off it yet...)

Thanks for all the comments and help,

cheers,

Jacob
