The modern Morgans have the fuel pipe and return on the outside of the chassis and passing into the engine bay through a "one inch" hole just forward of the bulkhead.
The pipes are extremely close to the exhaust. Less than an inch and in places much closer, which is why I add heat resistant weave to the pipes. In summer it gets hot under there, especially in traffic.
At least the return to the tank will cool things down a bit.
On the side without the exhaust - no problem.
