Right behind the Rear Passanger tire is of course where the fule lines are. At least on a 83 2+2. But i think something is missing. There is a mounting braket. with three holes. looks like two wires (electric) and a rubber fule line run right where what ever is supposed to be there. Any clues?

 

Sounds like somebody jacked your fuel pump!

well. at least i located where it's supposed to be. probly y i have not been able to find it.

 

a fuel pump is gonna kill me. I had to go to Las Vegas to get hood vents and door hinges.

 

whatever you do dont use an auto parts store pump! i went through a couple brands until it occured to me that they all put out to much psi. my z was running so horrible( if i could keep her running ) that a few people asked if i had a v8 in it. it got me home, but i would go with a rebuilt or new one.

 

i got one priced at autozone for $99. But i will most likely just pull one from another Z if i can find one

 

Becareful when you pull it that you don't let it drop in the dirt at the junk yard. Don't ask me how I know this after getting gas all over myself BEFORE I had to go to school. After I ditched the DIRTY pump my shop teacher told me how I could've flow cleaned the pump with mineral spirits, a battery and and bucket to get the dirt out. Lesson learned. Went back the next day and pulled another one. This time I pulled the hoses off before I cut the wires

 

And I don't see why an Autozone pump wouldn't work. Autozone seems to hustle Bosch enough so I'm assuming they quoted you a Bosch pump. And since the L28 fuel injection is designed and made by Bosch it would make since that the Bosch fuel pump would work with the Bosch fuel injection. Its funny though how the ignition is a whole nother story isn't it? Dont go bosch on that side

 

It's been said here many times before, and I have personal experience with this. DO NOT PUT AN AUTOZONE FUEL PUMP IN YOUR CAR!!! Unless you A: want to replace it again in 6 mo's. B: want your car to run like caca. or C: think it's worth saving a few bucks just to have it pissed away when you realize you shouldn't have put it in. If you're gonna put anything other than a factory OEM pump in that car... you better make sure it say's something like Walboro on it (Of course then you'd probably want a RRFPR to go with it). NAPA has the OEM pump in stock for a good price. Yeah, it's gonna be about 25-30 bucks more than that cheap autozone crap, but you won't have to worry about it. I HAVE LIVED THIS NIGHTMARE... I Don't want to see someone else go through it for a few bucks.

I don't know.....I've had one from Autozone in my car for 3 years now and it's run flawlessly. Think it was $79 then. Car runs great, too. I was just trying to save money at the time, and would've gotten a better one if possible, but I haven't had to deal with it since then...

Maybe I've just been lucky...

 

I've got a used one from an '83...

 

Hey Carl,

Correct me if I'm wrong, but didn't you mention something in one of your posts recently about a slight runnability issue that you just could never figure out, but wasn't that bad and so you left it alone? Or was that someone else? I can't remember and I'm too lazy to try and find the post. Coulda been someone else. Anyway, There have been several posts here that all lament the problems with using an autozone fuel pump. If you've got one, and it's working well... You're the lucky one. Those pumps are about 1/2 the diameter of the OEM pump and they are "Universal". They don't put out the right pressure for your car. It may run, and even seem to run well, but I guarantee that if you swapped it out to a new OEM pump, you'd be amazed at the difference. You could be running dangerously lean and not even know it.

I don't know if you remember, but several months ago, I was having weird problems with my Z. If I ran the car for a while, shut it off and then started it back up, it would sputter and die. You had to force it keep running for about a minute until it cleared up. Well, I had an Autozone fuel pump in the car that was less than 10 months old (Also the second AZ pump I installed because the first one came out of the box defective). I "Shotgun Diagnosed" the problem and replaced all kinds of stuff. Now granted, a lot of it I was planning on replacing anyway's. But, after new injectors, new FPR, New filter, plugs, wires, cap, rotor, Vacuum lines, EGR, BPT, T-v-v, cold start valve... several hundred dollars of stuff... still had the same problem. After all that, I took out the AZ pump and put OEM back in... car ran like a raped ape. No more sputtering... nada. It had basically been running so lean that when it got hot and you shut it off, it was vapor locking. So, there's my story with the AZ pumps. Maybe you got the rare good one...

Rod,

I'm certainly not saying that anyone should cut corners by buying a cut-rate pump. My problem recently usually gets fixed by new cap and rotor, and sometimes new plugs. I recently went with new NGK plugs, and I can tell the difference, but am still having a bit of hesitation at 3k in 2nd and some in 3rd. I'm going to try a new fuel filter, since it's been awhile (3 yrs), but haven't written off plug wires or possibly the pump. I've just been lucky with the pump I've had. I would definately advise anyone to get an OEM replacement. If I have to change mine again, that's the way I'll go....

It's probably good that you questioned that so that I could get the whole story out, and hopefully people will just spend the extra and get a good pump...

Thanks and good luck


BTW, your car is looking better than ever. Those rims are sweet, and when I get the $$, I'm gonna look for something similar....

 

Bleach tell me what ya want for it. I will talk it over with the old folks. Well an OEM sounds good. But i am on a strict buget now, and a Autozone pump last 6 months would be good. by then I will have a job, and a much larger buget for the 280. My biggest change being done to the 280zx on the next year would be the front end being replaced. and 3 inch lift. and a 5 speed tranny. After those changes a fuel pump will seam like nothin.

 

I guess if you reread your post here you'll realize you've answered your own question. If longevity and reliability out of the pump are not concerns of yours then you may as well go for the cheapest one you can find. And if you're that concerned about it you can get the manf. info on the pump and find out flow rates and pressure of the pump. And autozone generally provides a warranty for all the parts they sell. I don't know if the fuel pump has one or not but if it does and you're only trying to squeek by for 6 months then you really shouldn't be concerned with which pump to buy but rather which pump you can afford.

 

Maybe you should repost this in giant bold letters. I don't think he saw it Hey fubar you might as well ask him what he wants for it. Couldn't hurt to ask plus you'll be getting an "OEM" pump

 

I can always PM him also. I was just giving him time to think bout it.

 

. . . . . .lift your Z?

 

Probably the rear...

 

I have been in the south for 10 years now. i think i have to much redneck in me. Find an old Subaru. rip out front end. modify to fit Z. transfer case. 5 Speed tranny. 3 inch lift. bull bar. P235 A/T's, two ten foot CB bull whips on rear. But don't worry, it will most likely never happen.

 

When I lived in Nebraska there used to be this Monster Z (S30) sitting on a corner of somebodys property. It was Orange with these huge tires. And I mean Monster, the bottom of the car was like 3ft off the ground!!! It had solid axles, 4whl drive, and one hell of a modified frame that the whole chassis was just welded too. They just fabbed a frame and suspension then dropped a Z shell on top of it. The thing was covered in mud so I know they took it out and had some fun with it.

 

Well, If i were to do it, it would remain indapendent suspension. and I would not lift it but 3 inches. Plus it would still be a daily driver. I will probly just put some new P195's or move it to P205's street for now.

 

well . . .not my style but if you could pull that off and have it be a daily driver, more power to you. all you would need after that is a nice orange paint job, a big 01 on the side and name for it . . . . . maybe "general Z"

 

I just bought a pump from kragen and havent installed it yet. Its really heavy, made in USA and comes with a lifetime warranty. I was having cold start and hot start problems and thought fuel was siphoning out of the lines, but that wasnt it. Hey, do I really need the fuel damper? And why is there an inline filter on the vapor line on my tank? Is there supposed to be a seperate check valve on the fuel lines like in the Haynes manual?

 

Keep the fuel dampner. Unless the pump and the rest of the fuel system is fully capable of handling electrical and pressure spikes don't toss it. If you've got a high performance ride you can get high flow versions from companies like Vortech.
