Diesel fuel on plastic and rubber parts is definitely to be avoidable as much as possible.
Coolant hoses don`t like it for obvious reasons.
Same is true for all detergents/chemicals (engine degreasers,engine shine etc) whatever that makes chemical contact with the rubber other than dust or clean water.
Diesel engines are often oily greasy leaky what they should NOt be at all. Try keeping it neat and locate the leaks if any. I like looking under the car prior to every trip so there`s absolutely no engine guard under mine... (might help with cooling too but the main reason is to see what gets on the pavement and where. and when. and how much.)

Mine has very thick-wall, stiff heater hoses under the pump which HAS been dripping `some` fuel here and there but nothing crazy. It`s been going on for a few years (=1000s of miles) but luckily never an issue of a blown/cracked hose. It mainly occured when I switched pump diesel to biodiesel back and forth. The seals didn`t like that. BUT, you could try getting some true b99 biodiesel and run it through your pump from a jar to see if it helps the seals normalize temporarily)

Diesel on hoses isn`t good. There is always a high(er) risk of failure (or yes even a total engine loss) when this condition persists. If your hoses haven`t been replaced for many years, it is always a great idea especially after resealing the pump.
Kits are available for the job that is not as easy as it sounds but at least not too expensive (around $40 i think). (resealing)

PS. In my opinion, if pump constantly looks a bit wet only, not more, you might escape with the bio but you said you see fuel reaching the ground. That might be too much of a fuel leak. Especially when throttle is wide open at higher rpms. Your mpg may improve after the fix, lol. Try checking your fuel hoses at filter connections and even at the injector return lines, the banjo bolts, ip clear hose too etc...you might* find it out not being the pump itself. As a first step you may clean the area and inspect on a regular basis. Problem is that all that fuel(-vapor) crap keeps flying all over with the draft, landing on engine parts as you drive.
Rear belt too hates getting dipped in diesel, but at least nothing major happens when that one breaks. Other than a towing bill.
I hope this helped some.
