How to change 1993 5.7L
There are plastic clips on the sides which need to be released, usually either by pushing inward or by pulling back, and then you just give a yank backwards with the whole thing. The seal is by an o-ring inside. You can purchase both the male and female assemblies at your parts store, and it's a good idea to replace both, I've found. If I follow your question correctly, your female side is screwed into your manifold and the hose is the male side.
Turns over but won't fire
Did you do a tune up on the vechicle? Does it sound like it wants to start? It could be the spark plugs.

First you need to check if your clutch is moving. Does the pedal move freely and easily, or is there resistance? Second, does the throw out bearing arm move with the clutch pedal and cable or, when you move the pedal, is the arm sticking out of the transmission stuck in the pushed in position? If there is no resistance and the arm is not moving, you may have a frozen cable - there's little in the transmission to cause this problem since you stated you can shift into the gears.. You'll need a helper to push the clutch pedal as you push and pull on that arm. That arm will have either a cable or a small cylinder attached to it - I believe you'll find a cable. If that cable ( which is connected to the clutch pedal ) won't move then there's your problem. You may be able to lubricate it for a temporary fix but ultimately you need to replace it. If the cable moves fine as well as that arm then you probably have a broken disc in your clutch and will need to have it replaced. Unfortunately there is no quick fix if the cable moves. If it doesn't and you don't have any lubricating spray, get some oil from your kitchen and pour some on the end of the cable at the tranny and try moving that arm back and forth - you may need a screwdriver or other tool as an extension to help.
Good luck!!

Finding a gas leak coming from the gas tank
Take it to a shop, have them put it up on a lift and find the wet spot on the tank, it leads back to the hole. Often times these occur when road residue and trash build up and trap moisture on top of the tank, or between the bottom of the tank and a cover or or skid plate.

No, they use the same computer. But the prom chips in the computer are different. It will run fine on the 4.3 chip but it will run better with the V8 chip. After you switch it, I would order a performance V8 chip for it.

You got a short circuit. I'd be willing to bet, where it is. There are 4 bolts on the the outside of the frame, just beneath the driver side. this is the front bracket for the gas tank. Loosen all 4 bolts, then get under and take a peek at the inner frame between the bracket and the four loosened bolts. Make sure the bracket isn't pinching the wires to the inner frame. You know what to do if they are.
Truck has no electrical current (power) throughout
Sounds like its not grounded properly. Make sure your battery is grounded to the frame and the engine block. This way the assorted accessories and whatnot, that has (Pos.) power via wire connection, that is mounted to the frame or block, will successfully complete the circuit.
