914World.com _ 914World Garage _ Pulled the gas tank
Posted by: championgt1 Jun 17 2008, 10:05 PM
Well I decided to pull the tank after finding out there is no filter up front( pump has been moved up front) and seeing very bad fuel lines up front. Good thing I did, the filter sock was shot to say the least. The area under the tank is in fairly good shap with a few spots of rust and alot of dirt and grime. The rust is not structural which is good.
I am not sure if this is the first time the tank has been out or not. It is amazing what you will find in the area under the tank besides dirt, grime, and rust.(razor blades, paper towels, washer nozzle, snap-on tool, sanding disk, ect. ect.)
Suprisingly the inside of the tank is pretty clean. The outside has a few areas of light rust which I will clean up and paint. 
So instead of replacing the filter it will be a little more involved. (While your in there syndrome)
My plan is to clean the area under the tank with oil eater, and give it a hot water bath, use some mar-hyde to convert the rust and then paint everthing.
This will be my first experience trying to git rid of rust and also painting. I hope it turns out good. Stay tuned for updates and pictures as I progress along.
Jack

A few more pictures.
While I am up front I am also going to clean up the front trunk and paint some areas there as well.

Keep up the work Jack... Someday we'll get to see your car on the AX course 
Posted by: championgt1 Jun 17 2008, 10:35 PM
Thanks Jon. While I was contemplating taking out the tank I did manage to get my new Triad installed. Sounds like a million bucks even at just an idle. Can't wait to hear it at about 5000 rpm.

While you are in there, (ha,ha) you might check out your cold air blower. I think the tank has to come out to get the blower out and I'm sure you will not want to pull the tank again anytime soon.
I need to get my blower out and I'm just putting it off till later. I know I will need to clean up the tank and tank area then also. Wish I had your energy right now.
Yep, them Triads do sound nice, don't they. Wife says too loud, what does she know?! I back dated my 76 with dave's sshe's and the Triad all at once. Lots of bucks, but the sound is soo nice.

Danm that looks suprisingly clean
Jack, OT, but but what shocks to you have on the rear?
Posted by: Root_Werks Jun 18 2008, 08:02 AM
Under your gas tank area doesn't look that bad at all. Clean, clean, clean and paint, assemble and drive!

Thanks it is pretty clean underneath. I am not 100% sure what shocks it has. Car has the factory front and rear swaybars.(apperance group) not sure what shocks came with that. I doubt they are the original ones though. I am guessing bilsteins for shocks.

Have a close look at your tank where it meets that felt pad on the driver's side. That rust stain looks bad. On my car the felt pad was wet and lead to a rust hole the same size as the pad.
Inspect your tank and remove the felt pad and replace with rubber.

the exterior tank rust hasn't even pitted the surface. more of a stain. debris accumulated inbetween the spot on the tank and the pass side of the well. jack's car would idle and die or not start at all until after a few minutes of the pump running. air bubbles were evident while cranking. no filter was installed after the tank outlet and prior to the pump. the screen looked as tho it had folded over because of being plugged when under suction. show the old tank screen jack. clean it up and let's put the tank in.
i've read in a few threads of priming the pump with engine oil? is that correct?

Just took mine out last week! What a dirty mess... Would recommend asking the PO about the condition of the front fuel lines if buying a used 914--I was lucky I pulled mine because the dry-rot on the hoses caused an immediate leak...
Where can you get thick rubber padding to replace the felt?
Thanks,
Kris
Posted by: URY914 Jun 18 2008, 10:25 AM
You can use anything you find for the rubber pad. Cut a piece out of your "WELCOME" mat.

jack, check out the pump thread at club and post a pict of the pump as it's currently configured.
jack's car has an odd configuration on 2 of the lines, t'd on the r&d ports iirc.

Sorry, this is kind of a hijack;
I keep hearing about the need to prime the gas pump upon fuel tank re-installation. I have removed my fuel tank several times, and even replaced the fuel lines with the stainless-steel lines. Not once did I have any issue with the fuel pump failing to work properly.
What is the rational behind the idea of priming the fuel pump with motor oil, and how real is this issue?
My thanks!

Here is a picture of the filter sock that came out of the tank. It has a tear at the bottom and you can see how it is collapsed. My thinking is that under suction it just sucks itself flat thus low or no fuel flow. We will see.

while you are there...
1. add front sway bar
2. replace fuel lines
3. move fuel pump to front
JMO.

Okay--the replacement to the felt is right under my nose--cut up an old MOUSE PAD!
(my $0.02 for the day..)

I have been thinking about this. Great idea! I think I will try that.

targa top headliner felt. everyone has 1 extra top, right? while the tank is out now would be the time to r&r the thru body anti-sway bar bushings.

Home Depot sells square felt furniture pads for protecting floors. These come with adhesive on the backside and are perfect for padding the gas tank. I don't worry much about moisture as my 914 rarely sees the rain.

Spent about 2 hours tonight cleaning up the front trunk and area under the gas tank with some oil eater and a little elbow grease. Much more to do, but so far so good.

take out your fresh air box and clean out the 30 years of leaves and pineneedles that have accumulated in there ...

AndyIf you’re going to do that, repaint the fresh air intake grille back to black.

In this pic it looks like there are " rust trails" on either side of the air box from water leaks thru the windshield wiper bases. Mine has the same, does anyone else agree that's where it's coming from?

Well it has been a little while since I have really had an oppurtunity to work on my car. Got about 3 hours in tonight. Cleanup is done and all the rust areas have been given the Mar-Hyde treatment. Rust turns black, pretty cool.
Friday I am going to tape everything off and paint. Hopefully it turns out good.
A few pictures after cleanup and Mar-hyde.

Another picture of the area under the tank.
Also replaced the outer fresh air tubes that were bad.
Posted by: championgt1 Aug 25 2008, 01:17 PM
Been awhile but got a little more progress done today. Tapped off all the areas I did not want to paint. Put on a couple coats of paint. As soon as it dries the tank will go back in.

Pay super close attention to the sway bar bushing and mounting bolts through the fender my Dad just removed his tank and it was not good ...its gonna require welding and plates for more support.....and hey paint that screen on the fresh air intake ....good luck
and clean the fresh air box
Posted by: Phoenix 914-6GT Aug 25 2008, 01:45 PM
Yeah... it is supposed to be black 
So are you going to have it out at the AX on the 30th?
Posted by: championgt1 Aug 25 2008, 02:34 PM
Sway bar mounting points are good. Bushings are pretty new.
I would like to paint the screen but am sort of afraid to take the system apart.

Looks like your car was hit in the front at one point. You have a factory replacement front panel ...
AndyPosted by: championgt1 Aug 25 2008, 03:51 PM
Sorry for the dumb question. Andy, what panel are you talking about?
Posted by: Phoenix 914-6GT Aug 25 2008, 04:00 PM
The one at the very front of your car. There looks to be a few circles that are filled in. The cars came from the factory with those holes open and with plugs in them. Look at the picture of you wheel well that looks to the front. You'll see it. Right by the wiring harness.
Posted by: championgt1 Aug 25 2008, 04:21 PM
Thanks Jon. I see what you are talking about. Hit huh? No shit!
Posted by: Phoenix 914-6GT Aug 25 2008, 04:33 PM
Very comon for that area on these cars. A 10 MPH crash will cause it to be replaced and not damage anything else. Car looks great Jack. I can't wait to see it in person.
