ok so i was reading the FSM about installing my new fuel pump and it says lift up the rear mat.

so wait...i dont have to drop the gas tank? i can install it by just lefting the carpet off the back? if its that easy then its gonna get done a lot sooner....wow...

let me know if im wrong but it seems like it will be simple. i was just worried about having to drop my tank.

whoa cowboy, it may seem easy, but most FC's have rusted in screws that hold in the pump. Make sure that you have an impact driver to get them out, or a drill. Personally I'd use the impact driver, last thing you want is to drill it, get a spark (who knows) and then kill yourself.

But other than that, yea its easy.

haha i understand...i need a new compressor. the one i had was like 20 years old and it finally died...ill have to use the drill i guess. ill make sure i have a fire extinguisher nearby and i drain the gas first....maybe try to tape off a small area so the spark cant get too far...just in case....

Wow, sounds like it sucked for you On my 86, the screws are still perfectly fine.
MattB - To answer your question. Yes, it really is taht easy. I was also hesitant to take out the pump the first time (thinking I had to drop the tank), it turned out that I had my pump out in a total of about 5 minutes. There's 4 phillips head screws taht hold the metal plate on underneath the mat, then on the gastank itself, there will be 6. If yours are rusted, plan on a bit more time, maybe a half hour or so. To avoid spark, I'd wear a grounding strap if you have one handy, if not, make one out of some scrap wire, wrap it around whatever tool you're using, and alligator clip or contact it with the body of the car. That should ground you and eliminate the possiblity of sparking.

The connector for it is on the shock tower to the left (The driver side one). Installation is reverse of removal.

thanks...i was thinking it would take like a weekend just to do that but i guess i can throw that on my list of things to do this weekend...


TPS
Fuel Pump
New Rear Calipers
Electric Fan


a fun filled weekend with my 7

Syonyk

TPS: Shouldn't take more than hour to replace & adjust, and that's assuming a few beer breaks.

Fuel Pump: About an hour to an hour and a half. Make sure you do this outside, and clean the top of the tank off before you open it. You don't want junk falling into the gas tank. This is also an IDEAL time to clean out the low pressure fuel filter - you'll have it sitting out in front of you anyway.

New Rear Calipers: Could be a pain in the rear, but probably not too bad. 2-3 hours with beer breaks.

Electric Fan: Depends on how you wire it.

Anyway, yea. Sounds like a fun weekend.

i dont think u should drain the gas tank tho. its more dangerous empty then full....with it empty u have nothing but fumes in there. when i did mine it was very simple....and do like syonyk said and be careful not to let anything get in there....then u might be drainin it.

I used this site as a guide:

Only problem I had was loosening the screw on the bottom of the fuel pump holding the rubber stopper on. It was a PITA (only the one screw)! I''d change the tank oval gasket too while your at it.

MattB

nice...thanks guys i should be able to get it all done this weekend no problem. one problem is i cant have any beer breaks...being 17...aquiring alcohol is not very easy.

MARTIN

I used some vice grips and clamped it on the head of the screws. And then just buy some new screws with it.

One thing to pick up tomorrow before you do this is defiantly a new fuel filter "sock" or "low pressure filter" as Syonyk called it

don't mistake grinding / drilling type sparks for static discharge sparks. A grounding strap MAY eliminate electrical sparks, but not the metal on metal friction type sparks. Try puttting ground strap on a piece of metal and putting it against a grinding wheel, its still going to spark, they arent electrical discharges, they are small, flying, molten pieces of metal
just something to think about so you dont get blown up

just to let you guys know...the ignition point of gasoline is 500*F...so i doubt you have to wory about a random metal spark setting it off. Don't believe everything you see on tv. Even a lit cigarette butt won't ignite gasoline.

now electrical sparks...that's a different ballgame

the FIRST Thing on your list of stuff to do this weekend is pull up the plate that covers it (do it NOW even!) it's just 4 screws into plastic... and SOAK all those screws on the fuel pump cover with penetrating oil, do it like once a day till the weekend, and you shouldn't have much trouble with the screws.
make sure the screwdriver that you use is EXACTLY the right size.

I'm hoping that anyone who is working around any explosive chemicals realizes the difference between grinding sparks and static sparks. Obviously use EXTREME care if you have to use a grinding disc or whatever, but a grounding strap is always a good idea when working volitile chemicals.

X-JaVeN-X - Noone is suggesting that the whole tank is goign to blow up due to sparking, as the ignition point of gasoline liquid is so high. What we're worried about is gasoline VAPOR. the vapor form of it ignites off of almost nothing. and once that catches, the liquid will just continue to burn.

You don't need a compressor for an impact driver, it's just a small hand tool you hit with a hammer. Do a Google search to get a pic of one. This job is the perfect excuse to go buy this very useful tool. They don't even cost much.

MattB

oh yeah...i was thinking impact wrench for some reason...


and as for blowing myself up....ill just use a grounding strap, and then just drench the bolts in penetrating oil. hopefully by the weekend they will be easy enough to get out and i can just use a screwdriver....
