Radiator Hose replacement hell

So I am working on my track Elise and I notice a bit of coolant leaking and I finally track it down to the passenger side radiator hose.

Well guess what! The hose that connects to the engine goes into the frame rail and the hose clamp is in the rail! As best I can tell so far, to replace that hose requires removal of the shear plate and fuel tank! There appears to be no other way to get at the hose clamp.

I think this must be right.

I guess the up side is that I can really inspect the fuel tank and see if I can learn anything about the fuel starvation issue when turning left.

Am I missing something?

I have to say that this design feature is appalling, as radiator hoses are relatively frequent maintenance items and to have a hose clamp this inaccessible is IMO inexcusable.

Nothing to add other than welcome to working on a Lotus.

For comparison's sake, if you'd like a car with no woodruff keys on the cam gears, where you have to drain the cooling system in order to change a belt, or you have to completely pull the cam towers in order to adjust the valves?

That'd be a 4-cyl Esprit.

I remarked to an engineer friend, while working on his engine from the trunk of his Esprit, that it was amazing to me that an engineering company could do such a poor job of engineering.

torque (tŰrk) n. - an excuse for the lack of momentum.

Since it is a track car, I am this close to running a new Hose in an accessible location

Got the radiator hose off, had to remove: shifter cables, e-brake cable, shear plate, all fuel lines and fuel tank and then could access the hose clamp.

Next week I will take the sender and pickup out of the tank and see what I can see that may have a bearing on fuel starvation. I can say that the shape alone (long and skinny) could lead to starvation absent some kind of good-size sump.
