914 injector leaking

[dpegan]

We have a 1970 1.7 liter 914 with a major leak in the hose section of one injector. Any suggestions on how to fix the leak, short of repalcing the whole injector? We have been told that the hose only can not be replaced. Must the whole injector be repalced?

Thanks for your recommendations,

Cut off the crimped-on clamp that holds the short section of hose onto the injector. Remove the old hose, slip on a new one. Use a fuel injection-type hose clamp, not the common worm-screw type that is more common. The Pep Boys near my house has both high-pressure hose and the FI type hose clamps. Pelican does as well.

You may have to mess with things to get the length of the short section correct so everything fits nicely and the hoses do not kink. The pre-formed curved hose sections were, last I checked, NLA. Another run may have been made by now; not sure.

Dave,
What's the reasoning in using a fuel hose clamp over a common worm-screw clamp?

[Dave at Pelican Parts]

The worm-screw clamp is designed cut into the hose, which weakens it. The fuel hose clamp doesn't do this, and even has rolled edges to keep from cutting the hose. I believe that the worm-screw ones are designed for lower-pressure applications, like carb'ed fuel systems and vacuum hoses. The fuel hose ones are designed for high-pressure hoses, like our fuel hoses.
