Hi, I've been a member here for a couple of years, but haven't posted a lot of topics. I believe it's time to change the fuel pump, but I'm not sure exactly how to do it. Does anybody know of a link/forum/etc. that has some info/instructions on a DIY? Thanks.

 

Depends how you want to tackle it, from the top or bottom. You can do the trap door method and get at it from the top which will be much easier then dropping the tank from the bottom. Type in "trap door" method in the search engine and you should pull up the old posts with links that give detailed instructions.

 

I just saw that I was asking for the wrong thing. Instead of replacing the fuel pump, I actually meant that I want to replace the FUEL FILTER. I know the difference in the two, etc., but I was on my way to class, and was in a hurry. Sorry about that. Anybody know of a link for a DIY? Thanks.

P.S. Thank you very much, 2000GTP, sorry about the wrong question.

 

in my opinion, the trap door method takes longer to make than what it takes to drop the tank. just unbolt the lower shock mount and the tank straps. very simple. 4 hour job start to finish in your garage

 

Fuel filter? No need for a writeup.

Lift the car up a bit on the driver's side, near the rear wheel is the fuel filter. One side is a plastic fitting that pops off, the other you do with a wrench. Just replace it and call it a day.

 

The fuel filter is a piece of cake. You'll find it about a foot or 2 in front of the driver's side rear tire. It has a quick disconnect on one side and a line fitting on the other. Relieve the fuel pressure beofre starting otherwise you'll be wearing gas. Shoebox has a great write-up: http://shbox.com/1/fuel_filter.html

 

Is "depressing" the Schrader Valve just pushing it down? I know these are dumb questions, but I just wanna make sure. Thanks.

 

Correct.

 

Yes, the Schrader valve is like a valve stem on a tire, pressing the center post will relieve the pressure (and get your hand wet with gas).

 

have a coffee can or suitable container handy and some rags. Sometimes more gas is lost than you would think. I've changed the gas filters on all my cars but one (it will require line replacement) and sometimes it's a hassle and a mess. You probably won't need it but auto parts stores have kits to replace broken plastic gas lines. I had to buy and install one (in near zero temps) on my son's car.

Have all your tools right at hand and think it through on how you are going to get the filter in place. The quick connect end is where the gas seems most to keep draining so putting that on the new filter first helps alleviate some of the potential mess. I know some people can do it without spilling a drop but I'm just giving you my experiences on the last 10 vehicles.

 

That page has some great info, and got me in the right direction. However, upon inspection of the Schrader valve, I could not locate it. Then, I noticed on the image of the Schrader Valve, it was for 94-97 LT1's, and I have a 93, so I guess either I don't have a schrader valve, or it's in a different place.

How do you relieve the fuel pressure on the 93 LT1?

 

The shrader valve is near the front on the LH side of the fuel rail on a 1993.

 

The Schrader valve is like a tire valve; remove the cap and press the center pin; have a rag there for the gas.
