Ford truck 4x4 Not mine , I had to change the fuel filter on a power joke , the filter was inside the frame under the cab so it was blocked on the left by the frame , right side by the trans , top by the cab floor & below with the trans crossmember , I had to use 3 wrenches approx 1/32 of a turn at a time to remove the cover , took approx 1/2 hr then reverse the proceedure to install the new filter , I can't think of a dumber place to put a commonly serviced part . What I need to also mention is it was outside lying on ice in the wind at -35* in the oil patch , I am sure there is a special tool for this but not where I was . Apparently what doesn't kill you makes you stronger .... really ?
