leaking fuel connector

[oldboat1]

Can anyone tell me how to replace the "O" rings in the old two-line pressure tank connectors? I have the rings, but can't figure out how to open the connector. It looks like I either have to pry out the brass retainer, or pull out the brass nipple -- either way, risking some serious damage. There must be a way.

Usually you don't have to open the connector. The manual explains to use 2 pieces of stiff wire. One pushes the ball inward and the other piece of wire (has a small hook) reaches in and removes the o-ring.

Many thanks. I'll need to make a tool and fool around with it. I guess the potential damage is to the new O ring when trying to insert it, but better to damage an O ring than the connector.

Hi Old boat<br />There is no way to install new o-rings in these connectore with out taking them apart. With the newer model connectors it is possible to polk new o-rings in as described in the previous post. To do this job you will need a long skinny punch, you may have to make one. Install punch in the hose end of the connector ans tap out the guts. Do this on each side. Be sure to catch the parts. You will have a spring,stopper,o-ring and brass bushing. Install new o-ring, wipe a little bit of gasket sealer on the bushing and tap it back in the connector. The hardest part of this is finding or making the punch. After that this is a five minute job.

Re: leaking fuel connector

Thanks to both. I managed to dig out the old O-rings and install new ones, but it was a bugger to get out the old ones (hadn't seen Alcan's post before working on it). I don't know if I damaged the spring mechanism on the fuel side, but the connector seems to work OK (7 1/2 hp '57 Evinrude). I'm also a little concerned that I might have pushed little bits of the old brittle ring into the mechanism. Getting the new rings in was not a problem.<br /><br />I have a couple more connectors that presumably will need the same operation, and I want to try Alcan's method. I hadn't tried that -- thought about prying off the brass nipple or the brass retainer on the other end, but gave up attempts before ruining anything.

Hi Oldboat<br />These connectors are getting hard to come by these days. If you have a few to repair you may want to take a little time and make up a jig to help really make this opperation a snap. Take a small block of wood (aluminium is way cool). Trace the outline of the connector, face down on one end of the block. Bore two holes side by side, so as to catch the guts of the connector when tapped out. Install locating pins (nails,etc) to hold connector in the proper position over the holes. On the other end of the block trace the hose end of the connector. Bore two smaller holes to corrospond to the hose barbs. This will provide for an instalation station. One end to remove, flip connector over, and install. Fast, easy and no doubt as to the quality of the job. OMC used to offer this kit in their special tools catolog.

Re: leaking fuel connector

Good stuff, Alcan. Think I'll try to come up with a jig like you suggest -- makes damage to the connector less likely. As you point out, they are a bit rare. I'm happy that the fix on the one I fooled around with is apparently OK. I initially was converting to a fuel pump, then decided it would be cooler to run this motor the way god and OMC intended. I had the chance to take a run with a nice '58 at a local AOMCI meet a week ago, and that ran so well I decided to stick with the pressure tank. I'm doing the same with a '57 Big Twin that I have waiting for the right boat.<br /><br />BTW, if you have some experience with the Gale Sea Kings ('56 vintage), I have another posting in the "other" outboards forum....<br /><br />Regards,<br /><br /> Curt (Oldboat)

Re: leaking fuel connector

Hi Oldboat<br />The old presure systems are very reliable. A person just has to understand how they work and their weeknesses (just like anything else). The trouble most folks have with them is the fact that this equiptment is 50 yrs. old now. Most all the rubber stuff in the system is deterioated. If a person will go to the trouble to overhaul the entire tank,hose and connector, they will have few problem for many more years. I saw your other post about the Seaking. I'm sorry I can't make heads or tails of it. I will respond there also.
