Filter King now fitted and plumbed to my mechanical pump with new hose.

The Silverline cutting tool was a very reasonable price and cuts fuel hose really well.

Hopefully the refurbished carburetor will be back in the next couple of weeks.

Hello Neil
Can you tell me which company you used to refurbish your carburettor. I’m not at the stage to do this, but I would be interested in hearing your thoughts on the result.

I've used CFS in Bradford, they advertise in the back of Practical Classics. I'll post how I get on once the carb is back on and working.

Hello Neil
I saw the advert in Practical Classics, I noticed that there are several companies that do carburettor refurbishment, have you used this particular one before?

No, they are new to me but they have advertised for several years. I mainly opted for them as they are local, so no transit risks.

I'm a bit late joining this conversation, but:

On my carburettor equipped HPE the hose connection tubes on the carburettor and the tank measure just over 8mm for the feed and just over 6mm for the return. To me that defines the size of flexible hoses required.  The tube ends are belled to provide a snug fit for the flexible hoses.
Not measured the pump connections.

I finally got to run the car with the refurbished carb and the Filter King for half an hour in mixed driving conditions; queueing traffic through to 70mph on a dual carriageway. At first there was a fairly bad flat spot/hesitation when pulling away, but I'm putting that down to a fouled spark plug, as this cleared completely after about 15 minutes. After that, super smooth and pulling away strongly in all gears.

Just the brakes to sort now before hopefully attending a summer of top events......

With a week to go before my drive down to Goodwood I finished the nearly year long upgrade to the fuel system by changing the rear flexible pipes. Definitely past their best. It's the first bit of what I would call proper spannering since my illness and I'm aching all over this morning....

Neil, the price list link on Classic Fuel System's Web site is broken. Would you mind sharing how much they charge? Also interested if they set float levels, idle speed, mixture etc as part of the service

The full rebuild was £145. Everything was ready to go except the idle speed that I set as per Capriblu's instructions (link below). I'm planning a bigger test drive on Tuesday but so far I'm amazed at the steady idle throughout the warm up and the tractable power delivery that the rebuild plus the addition of the Filter King has delivered.

If you do use CFS don't be put off by it being and old guy in his especially untidy garage. He appears to have done a great job for a very reasonable price.

BTW when driving back from the garage that did the work on the brakes for me I was pretty fuel anxious with the warning light on and the gauge needle hovering at bottom. For ease and H&S before removing the tank I pumped it out using my rubber bulb and was surprised to get out nearly 8 litres....

This fuel hose conundrum is confusing me more than it should. Since building my Berlina I have now replaced the fuel hose twice. The first change was instigated by visible cracking at the end when the hose was removed for carb maintenance. I decided I didn’t like the idea of the cotton over braid because it hid what is going on underneath.
Today the R9 hose I used to replace the braided hose was replaced again after little over a year of service because it was cracking.

After fitting the new R9 of a different make I cut open the 1 year old hose.
It would appear the inner liner was of sufficient quality to deal with e5 shell/esso petrol and the worrying external cracks where because the outer layer was moulded from a lesser quality material.
Annoyingly I don’t know where I purchased the previous hoses, so I am free to make the same purchasing mistake again.

Frustrating to say the least.

Hi Ian

I think the answer is to buy branded hoses from a known reputable manufacturer, not unbranded. There are also reports online of old R6 hoses being relabelled etc.

I bought Cohline R9 for the Spider

Plus one for buying from a reputable supplier and getting a hose that is fully compliant with todays fuels that can eat rubber. I suspect that all the decent hoses on the market will be for fuel injection systems which is probably overkill for Betas with mechanical pumps.

I'd also avoid any hose with an overbraid should be avoided, especially a steel one because you can't see the state of the hose underneath and, when it does fail, the result is a very fine spray or even a mist of fuel vapour. Not ideal.

Agree completely. And I thought I had purchased a cohline branded hose as pictured.
The hose that you linked is the hose that I have fitted this time.
Fingers crossed 🤞
