Hello everyone,
I’ve been developing a few aftermarket products for the 914’s over the past years. What I’m currently working on are replacement fuel line kits using all Cohline parts ( Porsche OEM). I would like to get feedback to see how much demand there is for this kit. Ballpark price is $200, but I still need to add up my cost on each kit.
The kits will include the fittings to the tank. I have a few extras, but i will have a core charge because the aluminum nut that holds the tube to the tank, which is a M18x1mm (really odd size), i haven't been able to find alone.
Here are the fittings attached to the shortened gas tank fittings-
As for the fittings to the fuel pump and other stock slip fit/hose clamp parts, there are two options. The first, which is probably what i will do for all cases unless asked not to, there are fittings that crimp to the hose like the other threaded fittings, and the other side is just barbed, so you can use a short peice of regular fuel hose with a hose clamp on it and the fuel pump/other fitting slip fit.
Or, i can leave the braided fuel line cut (i tape the end before i cut it to keep the braid from unwinding), so you can hose clamp it directly to the fitting.
I also would like to mention that these kits can very depending on how much "pre" work you want. I can send them in raw form, partially assembled, or fully assembed. Some want more, some want less, and i would like to accomidate to everyones needs.
They're close to being done, I'm waiting for a few more parts from Cohline, but heres a few pics of the lines so far.
Here are some more pics of the finished hard lines. Each kit includes a large (supply) and small (return) line-
The install:
Having the car up on a lift is ideal. With the engine out and right rear wheel removed, this process should only take 2 hours. I recommend that the shifter rod be removed from the firewall section and the speedo cable cover, as they make great pep holes to watch the tube end as you guild it through the tunnel. With the motor in the car, i imagine it would take maybe an hour more. I will be installing this kit on a few other cars, so i will be able to post my results later. If there is enough interest in this kit, i will produce them and make them readily available for purchase form GPR, because I work there. Other companies can purchase these from GPR (if you are loyal to a specific supplier) at a wholesale price. I will still need to talk to the recipient for specifications, and can drop ship.
The existing fuel line holes need to be drilled out with a 3/4" drill to allow the threaded nipples which are pre-welded on to fit.-
Here are both the lines with the pre-installed rubber O ring inplace-
Next, through the access panel at the front of the tunnel, place the ends through the hole-
Another view-
Next, carefully slice the stock front rubber fuel line gromet with a razer blade as shown below. You do not need to slice through the whole gromet, just enough to slide it over the two lines once they are in place-
Apply some lube to the gromet. I used armor-all, but anything slick will work. Then slide the gromet over the two tubes and push into the hole. Here is the final product-
Here are the fuel lines before i had a chance to crimp them. The braiding is a tin coated steel.
I will have two complete kits avaliable and one single line for a carburator kit avaliable. I make every kit to suit each application. I need to know where the fuel pump and filter is located, and if you want the flex lines to be routed other than stock.
I would definitly be interested for future projects, unfortunatly I am doing a couple of H2O cars right now. You should definitly be able to sell these here.Just a thought would to be to put a brief post with 1 pic in the garage directing people here to get better exposure.I know I don't check this section very often.
involved.
