there shouldn't be a filler tube, just a dipstick tube for checking the oil level. to put the oil in the engine, there should be a oil cap on the right hand side valve cover. if the dipstick tube isn't there, you definitely need to get one from a parts yard or store, you can be losing oil from the dipstick hole that goes to the oil pan...

It sounds like an ignition module failure or the ignition coil is overheating. If it is fuel injected, a fuel pump relay could be the problem

The F100 ended in 1983, so there is some confusion on your 1987 Ford F100. The F150 started in 1983 and was available in 1987, but not the F100. You have this listed under the 1981 Ford F100 category.
The 300 CID = 4.9L In-Line (Straight) 6-Cylinder.
In order to best answer your question I have included both the 1981 F100 4.9L and 1987 F150 4.9L below. The only difference is with the Distributor Cap Configuration and Connections.

For the 1981 F100 300cid=4.9L:
Firing order:

If your smelling alot of fuel without using the pedal at all the floats are most likely stuck open in the carb. Which will cause it to flood out. I would check for spark first the go from there.

we are a tech help site no links to parts, sorry, have you tried ebay, there are allot of vintage parts there like this column, have bought lots of parts for cars back to the 1940's on ebay.

you dont need to splice the harness ,look closely every thing will plug in you just need to take the distributor from the old motor and put it in the implant motor...if thier different motors get one from a wrecker that is the same year as the truck and put it in the implant motor
