Safety might be a concern, but I wouldn't exaggerate it.
But diesel runs with vacuum in the main fuel line. All available fuel hoses are rated for pressure, not vacuum. I used to have diesel motorhome with lot of hoses between two tanks, transfer switch, priming pump, water separator and filters. That thing was loosing the prime on regular basis, till I replaced all that mess with copper tubing and compression fittings.
If you engine is not loosing the prime, that means leaky pipe is return.
