what our the approximate cost to replace the fuel lines and remove the fuel tank on 1972 914 1.7

Posted by: Jeffs9146 Oct 30 2013, 11:10 AM

$159 for the complete ss fuel lines from http://www.tangerineracing.com/stainlessfuellines.htm

Remove the tank yourself and install the fuel lines....it is a simple job!

An experienced 914 guy should be able to do the job in about an hour, maybe a little more. That's IF the tank is nearly empty. Couple of hoses, change the strainer screen while you're in there. Might take you a couple of hours first time. There are some cautions, so ask for help if you're gonna tackle this. If you're in So Cal, there are a lot of folks who might be willing to help you. I'm a bit far away, or I'd volunteer. Many of us work for beer and food.

Can you elaborate on the cautions, tips and tricks? Of course the obvious cautions of not burning down your 914 or house, but others....

Or is there a tech article written up somewhere?

I'll be taking my tank out in the spring.

Welcome to the world!

I would estimate changing fuel lines in a 914 would be a 2 hour job + parts.
While you are swapping the lines you should upgrade to newer metal lines.
4 piece fuel lines for your car will cost $110 for stainless steel.
You will need rubber FI rated fuel hose (30R9) about 4 feet for $36. You should also change your fuel filter and fuel tank sock. Then you are done.

There is a SS fuel line install video at this link (post #3),,

painting tank, another day. finding the tank recess a dirty/rusty/general pig sty and taking care of it maybe another day. 3 days total. first time with the lines an extra set of eyes and hands makes the process go a lot faster. upon reassem be very careful not to drop the bolt for the tank strap. 99% chance it will bounce and fall under the tank. match the bolt to see if you have one ready for when the 99% bites you.

Lets not forget cleaning the sludge out of the tank, that timing depends on who and how it gets done and how backed up they are.

When you buy your stainless lines from Tangerine Racing, Chris also includes a great instructional sheet which really helped me.

Call him and he can tell you exactly what you need.

Don't forget to get 8mm & 9.5mm firewall grommets replace the old ones in your 914. You also might need fuel adapter piece too. Just ask Chris.

this is one of those jobs where if something can go wrong, it probably will. . . after you get the tank out be sure to inspect the inside for rust. . .

30 minutes to jack up the car and drain gas. . it's heavy if you don't and awkward to handle.
30 minutes to pull tank after making sure you know where the feed and return hose connects. . . .

1-2 hours to R&R the lines, add 1 hour if you have to pull the shifter to fish the lines through. . . they are suppose to be held inside the tunnel by bendable tabs from the factory and don't necessarily just slid in and out. .

1/2 hour to drop the tank in and reconnect mounts and expansion tank

1 hour to hook up all the NEW hoses correctly. . don't reverse feed and return lines at the tank and fuel pump. . and fit a new fuel sock.
So all in all,I'd say it's a 4-6 hour job. and that's without any leaks

Be sure to seal the ends of the new tubes with tape or a rubber cap before shoving them in the tunnel or they will scrape and plug up with dirt

You might have to get the tank cleaned out. . .You can do it yourself, it's a little messy. . . I used concrete etching acid from Home depot. . . It's actually Phosporic Acid, which is a rust converter. . .makes rusty metal shiny. . Dilute 50-50 and pour in a gallon, add a bunch of little nuts and bolts and shake the hell out of it. . or take it to a radiator shop. . they probably charge around $50 to hot tank it but that will take off all the exterior paint also . . l

It took me an hour to hook up the hoses to the tank from the bottom. Not much room in there for your hands or a screwdriver for the clamps. I had to use a small ratchet socket on the clamp heads to tighten. I felt like I was building a ship in a bottle!

I did not replace the steering cover until I placed a piece of cardboard under the hole and waited an hour or so to see if there were any leaks.

While you are under there you might consider replacing your steering cover seals. 914rubber has them:

That's a very informative video you produced, Robert ... and your SS fuel lines are great

I bought my SS fuel lines from Robert (Rotary'14) at one of the G&R swap meets, but I purchased the rubber grommets and some other neat misc parts from Chris at Tangerine Racing ... I like 'spreading the wealth' around (not to be confused with socialism)

I may have missed it, but IIRC, depending on your car's MY you may not have to drill out the front grommet. Early cars had 2 different size tubes, late ones used the same size.

I don't think the correct question was asked.. I should be how much will it cost if I don't change my fuel lines?

This wasn't from a tunnel rupture. Maybe from an injector hose or something but in this case it cost a car with a solid chassis.

I did this job last spring. I took my time, replaced all the fuel and vacum hose throughout the car. PO had cleaned tank really well but all the hoses were origional and fell apart upon removal. New hose got rid of gas smell. Also did seals on the top of the tank. I had the engine out so the ss fuel lines went in very easy. 5 minutes with a "spotter" looking through an access port in the shifter tunnel. Very worthwile project. Just make sure to get alot of the correct fuel clamps. I bought most everything from Tangerine racing. Also sent in the injectors to be cleaned and replaced the rubber elbows.
