TR6 - BANG, fuelling advice please?

I changed my fuel tank during the winter as I used to get blocked injectors and the Bosch Type pump used to sound like a Bees next due to debris. Also old fuel line do allow vapour fuel smells due to the Ethanol.

Thing is, it didn't stink for the first month that I had it, and it does now, not the nice pong of a classic car, but the pong of fresh petrol, hence I think there's a leak somewhere.

TR6s do always have a whiff of hydrocarbons, mainly I think due to the fuel tank being basically in the cockpit separated by a bit of cardboard, but also esp. the PIs with a fair bit of extra plumbing and unions etc. (I've put in a sealed alloy firewall which helps, and Revingtons do special fuel hoses which help mitigate the smell in the boot.) But actual petrol smell definitely points to a leak – good luck!

Thanks Yertis

Another quick question if I may?

How do I change the rotor, is it just a matter of taking off the distributor cap, pulling the old one off and sticking the new (red) one on?

Also,is it easy to put a new petrol pump in myself if that turns out to be the problem?

I have the mechanical prowess of a polo mint.

Fire away, always happy to help if I can. With ref the rotor, you've already got the most import bit right (ie a red one, I'm guessing from Martin the Distributor Doctor, personal friend of mine). Your method is also correct. Personally I'd change the cap too. With regard the pump I have to admit that my experience with non-PI Triumphs is with the GT6, and I don't have the TR manual to hand. I *imagine* your pump if original is down on the left of the block, and (if so) is easy to change. However you may have some other arrangement.

I learned most of what I know from being compelled by circumstance to maintain my own TR as an impecunious graduate back in the '80s. If you get the original Triumph TR6 Manual (the brown one) and a parts catalogue you'll save yourself a fortune. You'll develop a different kind of relationship with the car.

I'm in Germany so got the rotor and other bits from Limora. Next day delivery too!

I haven't ordered a cap but will do so.

The pump is as you say, bottom left of the block, I'll change that next if what I do over the weekend doesn't help.

Right, I'm off to take the stinky old thing to bits

I have the brown manual already, came with the car, and a parts catalogue!

[Yertis]

You're all set then!

Ignition coil = sorted, all good again.

Oh and the source of the petrol smell, probably something to do with this.........

Split fuel hose.

Good work.

Not such a polo after all.

Modern fuel eats hoses for breakfast.

I'm replacing all of them, oh, and I put a fire extinguisher in the car last weekend as well

If you can get hold of Gates Barricade fuel hose use that it’s Ethanol proof

The other thing to watch with these from memory is the fuel pump itself.

Some of the Triumph engines with a camshaft-driven pump used a large 'rubber' diaphragm inside the pump. If the diaphragm fails it promptly dumps petrol into the camshaft gallery and dilutes the engine oil quite nicely. On the plus side, the engine stops due to fuel starvation so doesn't run for long with diluted oil.

Not sure the pump on this engine will have the same design, but worth checking for.

Have you got it running yet ..

If it runs unevenly then a good old mechanics sty;e clear out, drive it like you stole it
should help and crap get burnt by the engine.

[Adenauer]

Running okay, no fuel pump issues, I have bought one of these which I still have to fit and that should be that
