mechanical fuel pump replacement

I have and 84 S-15 with carbed 2.8L. Lately I've noticed a gas smell while driving my truck, and when i investigated the problem today, i noticed that there is fuel shooting out the side of the pump. My question is how hard is it to replace the pump? Is it easier to remove the power steering pump, or take off the skid plate and come up from underneath? Thanks

Re: mechanical fuel pump replacement

The method I use is to take off the P.S. pump. Make sure to hang it up with a bungee cord or mechanic wire or something so that it doesn't pull on the hoses. 2 bolts one on top and one on bottom of the pump (from memory they should be 1/2" or 13mm, but it's been about a year since I did that and my brain is on permanent vacation so I can't be totally sure on that). Use flare nut wrenches on any metal lines you use, saves a major PITA (pain in the backside) by preventing stripping of the fittings. Make sure to get that pushrod out so it doesn't fall out. A dab of grease on it seems to help keep it in there. Make sure not to overtighten the bolts. This is a very good time to replace any rubber fuel lines in the vicinity also since they're probably more than due to be replaced. In the middle of winter it took me a couple of hours (going into the house in between times to warm up included in that). If you get any fuel on you when it's cold out, go and rinse it off somewhere warm ASAP. As it evaporates it makes your hand extremely cold, and it seems it could hurt the skin.

But anyhow, that's my story...

Lucky for me, my dad works at the local water utility, and has full use of the garage after hrs. It is heated with lifts, and since he and the mechanic are buddies, he's got keys to all the tool chests.
