That isn't fuel, it is oil. The fix is to remove the pump and take it to an authorized Bosch shop to get the seal replaced. More than likely the rod will need replacing as well. It is the other end of the rod attached to the fuel shut off lever.

You'll just make a mess and have to add oil every once in awhile.

is there a temporary fix I’m in Kansas and need to get back to south Texas to fix it

Then drive to Texas. When mine was leaking I probably put it off for close to 50,000 miles. While you have it removed I recommend you take the opportunity to replace the side tappet gasket.

Does this make me look speed on hills or over pass when pulling a 5th wheel camper i also loos speed when not pulling what can that be I’m new to this trucks I have only own gas trucks

That's a pretty vague question. Is the engine stock? How big is the 5th wheel? How steep are the hills? Which transmission? An automatic was only rated for 160HP/400 TQ in 1995. A 5 speed wasn't much stronger 175/420. So yes, losing speed on hills would be expected with a trailer. An oil leak won't make it worse.

I got the truck in November and all I can see it’s stock and it’s a 5.9 automatic and what I’m pulling is a 5th wheel Rv 41 ft about 13,000 lb

I've boosted my power to over 300 HP and a 13,000 lb trailer will still slow me down. If you are considering adding more fuel to increase your power I suggest you do some research about the 47RH transmission. There is a reason why dodge put a lower powered engine in front of them.
