Crypty Died Again

We're getting those bad vibes here again...........

Dale, time for a nice walk on the beach and regroup...

NOW you tell me Triumphs are prone
to exploding into balls of flaming infernos.

Well, that's just GREAT news to learn.

Blargh!!! and double BLARGH!!

Your TR will easily surpass the Crypt Car in
miles driven during year 2007.

There is an automatic fire extinguisher system
they sell for boats- below deck engine compartments.
Maybe I should look into installing one in Crypty?
It puts out engine gasoline fires instantly.

I don't recall ever seeing a TR go up in flames. So, I wouldn't say they are prone to it at all. I've seen a photo of a burnt TR8, but I think that was a fuel injected car.

Speaking of which, on the highways of Calif. I've seen a pretty surprising number of late-model, fuel-injected cars in flames. Probably averaged about one car fire every month or two when I commuted 30 miles round trip (for 10 years).

Fuel injection has far, far higher pressure in those fuel lines than our old TRs do. Something to think about.

On the other hand, most racing orgs require some sort of on-board fire extinguisher, no matter how the car's fuel is handled.

Like others have suggested, it's possible just some gunk from the fuel tank plugged a needle valve in the float bowl, or another valve stuck open. That could easily cause a one-time problem and cars that sit a long time tend to built up a lot of junk in the fuel tank.

I'm sure your car has a fuel filter, others suggested changing it.

Personally, I'd consider getting one of those clear generic ones with the cartridge filter inside and adding it to the fuel line up near the carbs. That would both act as a secondary line of defense and you'd be able to see pretty easily if there are flakes of rust working their way through the fuel system. Any brownish/reddish crumbs would be a tip off that there's some rust in the bottom of the gas tank.

Another possibility is the fuel itself attacking the rubber hoses. Now, I don't now how they formulate fuel there, Dale, and this is probably more of a concern with cars older than yours, but some modern fuel formulas cause older rubber hoses to break down and pretty quickly disintegrate.

If you see black "crumbs" building up in a clear filter like I suggested using, that's probably a sign that any old rubber fuel hoses on the car need to be replaced. In your photos the hoses under the hood look relatively new and ini good conditioin. That would leave the ones back by the fuel tank, underneath, to be concerned about if you don't know if they've been replaced recently. It's cheap standard hose available locally, if needed. Modern hoses are made to tolerate modern fuel formulas.

I hope it's a relatively easy problem to sort out, or just a one-time occurance of some stuff that shook loose and has now passed through the fuel system.

My Bently manual lists fuel pump pressure at 1.5psi min to 2.5psi max. That is not much. My replacement original style fuel pump is over 5psi.


That pressure is in excess of that recommended by SU or required by the carbs fit to that size engine. It may work but it can produce Crpty type problems. We use the right tool for a given repair, why not use the correct fuel pump for the car?---Keoke
 
Alan,

Thanks FYI- I have less than 200 miles on the new,
generic clear glass fuel filter I installed up near
the carbs.

Brand new modern fuel connector hoses supplied by Jeff
with the new carbs.

Fuel filters sparkling white.

I replaced every hose, of every type, in the engine
compartment. Everything is new.

I will look into installing a new fuel tank.

thanks- for now, the car is parked until I sort out this
fire potential problem.

Dale, you probably do not need a new tank, but if yours has a lot of sediment in it, just have yours "Boiled out" at a radiator shop. If there is one on the island.
 
Paul,

DPO Pedro's cousin owns a radiator shop.
Pedro introduced me to his cousin. He had MOST
of teeth present.

Should I take it to Pedro's cousin?

PS: How many weeks will Crypty be dead again
in order to remove the tank and re-install it.

DPO Pedro doesn't seem to want get our my garage, does he?
 
Dale. I agree with the above. sounds like a needle valve got stuck. it dosen't take much. could have been a bit of rubber from one of the new hoses that finally got loose and stuck in there. Amazingly enough it seems that even when all that fuel pours over the exhaust manifold they very rarely go up in flames.
One of the nice things about the TR2-6 tank design is that shining a flashlight down the filler hole gives you a fairly good view of the tank. you should be able to get an idea of what the bottom looks like.
Keep calm. even though it seems big, this is a fairly minor issue. It's common to see a bit of debris in something that's had so much done to it. I'm willing to bet it was a glitch and it'll be fine with a bit of use and a close watch. If not, we're here for ya.
