PCV Hose on 2003 Ford F-150

I am getting my PCV Hose replaced in my 2003 F-150 and being charged $100. They said it is really hard to get to and would take them about an hour and a half to get it done. Since I am a returning customer he said he would just charge me $100 if I paid in cash. Is the hose, in fact, that hard to get to? Does this sounds reasonable?

its a bit high. the hose is about 35 and we charge .5 hours to replace it.
thats adds up to about 85.

i would never pay without a receipt. if he does not wan to give you one, then go somewhere else.
