2nd post, no help yet.

[irl]

I am a new member doing an extensive rebuild on a 74 coupe. I love this sight and stay up late reading driving my wife crazy but I am obsessed. I am looking for some info but I am not finding much help yet. I promise to send lots of gory photos along the entire way of the rebuild. I am currently welding a new front pan in and doing a complete front susp. rebuild and while the tank is out I want to completely replace the entire fuel line system. Where can I find the right materials or packages and sizes for the fuel hoses. I cant seem to find the parts or descriptions anywhere. I found one article on a 914 but it was very different.

Here is how it looks now, I have two sets of clear tubing running down the center channel and black rubber hoses coming out of the tank and black rubber hoses connecting to the rear fuel pump and hard lines. Braided hoses are currently clamped between the tank and clear hoses in the front to make the connection. It all looks very rough and I would like to replace them all this weekend. Is there anyone out there that can point me in the right direction.

are you looking to "restore" or simply rebuild?

If rebuild you should consider converting over to braided stainless steel and all AN-6 fittings.

Wecome to the sight. Sorry, can't be much help but be patient. As you know, there are alot of knowledgable folks willing to help. As far as your search check with our host and try the "search" button above. Pictures always have a way of peaking interest as well. Good luck. I'll look forward to following your progress. Remember the pics!

I am looking to rebuild it with what will run the best and the safest. Thanks for any help, especially with those clear lines in the channel.

Welcome to the board! For future reference it helps to put the question in the subject. Something like "Need help" isn't as condusive to getting answers as "'74 fuel line replacement".

A helped friend replace the fuel lines in his '74 a couple of years ago and we used black polymid (sp?) tubing for the lines in the tunnel. It's a rather hard plastic line that you soften in hot water to press over fittings. We have a metric place nearby that carries this hose and lots of other metric hose.

in my 1970 with a 3.2 I ran braided stainless steel AN-6 lines, welded the AN-6 fitting to the fitting on the fuel pump, and then another to a fitting at the motor. I ran the lines through a new hole into the smugglers box, through the tunnel, and out to the motor. Installed an AN-6 inline filter as well.

Works great.

call the pelican parts toll free line & ask for jason or bob. they may be able to email you a diagram of the fuel lines and answer your questions. i've been on this board for about a year and spoke to both. they answer the technical question and are very helpul.

darren is in sales and also very knowledgable and helpful.

good luck,

irl, I believe I have most of the information you need but you asked for quite a bit so I'm going to send it to you in installments.

The part number for the supply (or suction) fuel line in the tunnel is 911.356.067.01. Unfortunately, Pelican shows this as no longer available (NLA) but I can direct you to some fuel service rated nylon tubing that will likely work as a substitute. The return fuel line in the tunnel is PN 911.356.062.03 and is still available for $25.00. The black (or grey) braided rubber hose between the tank and the front of the tunnel is 11.8 mm ID x 17.8mm OD by 270 mm long for the suction or supply line. The section for the return line between the tank and the tunnel is 7.5 mm ID x 13.5 mm OD x 275 mm long. The 11.8 x 17.8 maps to Pelican part number VH-12-17 at $3.90/ft and the 7.5 x 13.5 maps to Pelican VH-7-12 at $2.80/ft. Do not worry about this being called vacuum hose as it is the same stuff used for the rubber sections of the OEM pressurized CIS fuel lines. More later. Jim

Measure the OD of the suction line (larger of the two lines in the tunnel). I suspect it is about 12mm (0.468") in diameter. If so you can likely use one of these two types of fuel service rated nylon line available on-line from McMaster-Carr ( www.mcmaster.com ).
Catalog no.: 8365K26 10mm x 12 mm @ $.81/ft or catalog no. 50405K16 10mm x 12mm @ $.76/ft. Do not just use any nylon or other plastic line as it may not be rated for hot gasoline service. Jim

[Jim Sims]

If you elect to replace the rubber bushings which protect the plastic fuel lines as they enter and leave the tunnel the PN is 911.356.202.00 for the bushing for the larger line; Pelican lists them for $8.50 each; two are required. For the smaller line the bushing PN is 914.356.201.00; they are $3.83 each and two are required.

The factory parts catalog shows 11 mm x 17.5 mm x 280 mm long braided rubber hose connecting the plastic suction line (at the rear tunnel exit) to the pump intake. This is PN 999.180.029.50 and it looks like it is available for $23/meter (?).
I suspect you could substitute Pelican VH-12-17 for this line especially if you install 12 mm OD nylon line as the replacement tunnel suction line.

The braided rubber hose connecting the double tee fitting (up on the engine) to the return line at the tunnel exit is 7.5 mm x 13.5 mm x 330 mm long, this again maps to Pelican VH-7-12.

Jim,
Thank you very much for the extensive effort you have put into this, this is truly and amazing database of people. To all others with similair years, this is very hard info to figure out, it should be filed somewhere for the future. And praise Jim.
