Truck pumps aren't too bad. Pull 6-8 bolts, jack up the bed. Faster than dropping a tank.

Fixing a distributor issue with a Chevy-small block Mopar- Y block Ford on the other hand... Time to swap in a 390 or 300 straight 6 and be done with it. Rear mount distributors should have resulted in execution of the designers, immediately, with the design never put into production. And whoever decided a crank position sensor and trigger ring was a better idea than a distributor should have been hung by the ankles until his bones disintegrated in the sun. I'm scrapping an otherwise flawless 4 cylinder Ranger because I'm sick of changing 1-4 $155 parts every other month. Cheap Chinese replacement parts, even from Ford dealership.

JOG,
 If you are working with the fuel lines get the stupid little fuel line disconnect tool. It was a big help with my '03 Tahoe. Wish pulling the bed was an option on my ride.
 I'm with you WD, miss the inline six cylinders, could swap one of them out in about 8 hours and a 12 pack.

Those Ford 300 I-6s were indestructable!

I know a heavy equipment mechanic. He had a problem on a machine.. instead of splitting the thing in half, he put a hole in the cast iron, fixed it,
He knew exactly where the problem was,
