Fuel pump, cutting out at 1/4 tank

Just a quick update on a problem I had with the discovery cutting out on a quarter tank.

Previously I had fitted a secondhand pump which works fine. After removing pump and actually engaging my brain it turns out the float arm had an angle of around 75 degrees rather than 90 like is shown on photos I found. So the tank was empty but reading 1/4 full. I should have paid attention when swapping them over.

I did check the part numbers which were the same but there we go. The arm didn't look like it had been altered either.

So bent back, filled up and a new fuel filter and it's running fine. Just taken me to Paris and back.

I'm sure this is not news for some but it could help someone. Thank you to Biolandy and Gemsdad for your help.

NOW THIS IS SCARY! The same thing happened to me just last night! I've recently had to buy a replacement pump - it was a cheap £64 jobbie - it works but it's a bit noisy.Anyway 1/4 tank and chug chug, nowt...
Fortunately I'd been dozing on Hilton Park services car park. Woke up, started the engine, tickover got lumpy and then cut out. Hmm.. just spinning on the starter with nothing doing. Began the purge procedure just in case because the pump and tank have both been removed for a recent welding job. Whilst the procedure is doing its thing I hit the tank and thought it sounds bloody empty.

So, £17 later from the garage for a gallon can and diesel, she fires up just fine. Drives round to pumps and drops £60 of diesel in the tank to make sure I got home. Yes motorway prices but I had no choice.

Will remove the pump and check the bloody float arm! CHEERS! :tea:
