The NOS SU fuel pump rebuild kit arrived in its 1977 MOD packaging and I replaced all the parts in my pump.
I put it back on the car and after spinning over for a few seconds she burst into
flames life. Yay...happy dance.
As I was able to put the pipework back exactly as before...... everything fits.
It has occured to me that a fuel-filter would be a good thing to put in, but there is very little room to insert one in the current layout. I have got some "bits" on the way to help form pipework into nice shapes so I may re-run all the piping from Pump-Out to Carb in and insert one in there somewhere.
I don't really want to put loads of nasty self-tappers through the bulkhead to secure any new/improved pipework.
Some securing clips for 6mm pipework that an be "ganged" on a single M6 bolt would be good. I shall go look.
Can you not put one in the pipe coming from the tank to the pump? If there is a bit of flexible then you could just cut it and stick one in, no need to mount it on anything. (Don't forget to check the arrow for correct flow, easily missed.) SUs are actually quite tolerant of cack in the fuel, it just sits in the bottom of the float bowl.
I once put one in the fuel line of a kit car belonging to W that she was selling. I'd done a lot of work on the car. The new buyers came from Cornwall to pick it up. Once they'd gone I celebrated with a bit of wine and a meal.
Then at about 10 pm came a phone call, they had broken down about 20 miles away.
Poop, I couldn't drive as I had had a drink but luckily I still had recovery on it, so I got it, and them, recovered back to our place. (W was away on business.)
I had a quick, quiet chat with the recovery guy as he couldn't see anything wrong with it, he put the tail down on the ground, I got in it started it and drove it off.

So I told them I'd fix it and deliver it once fixed.
Then I fed them, gave them a bed and in the morning drove them to the bus station in Bournemouth before going off to work.
The fuel filter was partially blocked up with very fine rust. It would run, but not well at all.
I realised that it had come from the fuel tank which originally came from a Triumph Spitfire. It had been rusty with a few holes so I washed it out to prevent it catching fire and gave it to a member of my club to weld it up for me. I realised that by doing that a certain amount of surface rust had formed.

So I cured it by simply removing the filter! It ran fine like that.
So the time came to deliver it, I was going to drive it and W was going to follow in her car. I got about 100 yards down the road and it caught fire, under the bonnet.

I managed to put it out by throwing a few pints of water over it that I luckily had in a plastic jerrycan, put in the car in case of overheating!
So it damaged the fibreglass bonnet and aluminium engine compartment side panels. It did NOT happen because of petrol, it was down to an old distributor cap and damp: condensation as it was early in the morning. So things shorted, sparks flew and plastic burnt. The insurance paid for the repair apart from a new dizzy cap and leads. But it took ages for the new bonnet to be made as the kit car manufacturer was not really doing much. It was an MGTF copy.
Did eventually deliver it without incident, to a couple of whom only the wife drove and the Cornwall village was so small few people had a garage, so it would have been garaged on top of the cliff/hill just outside it. Can't remember the name of it. She professed to be in love with it.
A year later it was on sale!!
