need some ideas for fuel sender, TBI

[ciffer]

I had a fuel leak, had to cut the supply pipe to run new hose. In the process of cutting the supply i broke sending pipe to close to the tank to fix.

I have a new sending unit but need a way to hook up the supply pipe, which is now fuel injection hose back to the tank.

There connections are visible in the picture attached, there is a male threaded connection (which seals with an o-ring) coming off the sending unit. the fuel line has been cut and no longer has the female connector or the original flex line.

I need a way to attach the sending unit to the fuel hose, preferably without cutting the new sending unit.

I was thinking of using a female connector that will either have a 3/8 hose barb/pipe or a female-female union which would allow me to use a male connector with a hose barb. the problem is that i can not find either at napa. the female-female union is available but is not deep enough to reach the threads on on the sending unit.

Let me hear your ideas.

You can cut the fittings off and run just the hose onto the steel lines. Be sure to use high pressure fuel line and high pressure hose clamps. Preferably 2 clamps at each end of the hose to prevent any leaks from occurring.

I ran this on my burb for 2 years with no leaks. A hole rusted through the line right where the line and sender meet together. The lines were also very rotted and wouldn't come off the old sender, so I cut the new ones and did as I said above.


Edit: I missed the part where you said you didn't want to cut the new unit.

IIRC the inlet hose is 16mm x 1.5 O-ring fitting so you could run this

http://www.summitracing.com/parts/EAR-9894DBJERL/ on the sender and frame side hardline and then make up a -6 AN fitting hose to connect at the hard line using the same fitting once again. So basically you'll end up with a new flex line that has -6 AN fittings on both ends to connect to the adapter fittings at the sender and the hardline at the frame.

i like the AN fitting idea but I don't know a lot about them. what is involved in getting the hoses for AN? I am guessing this would allow me to make a single run from the tank to the filter.as of current I have about $70 worth of high pressure hose and hardline, some of which i might be able to return.is there a way to use what I have or would i be better off biting the bullet and "doing it right" with the AN fittings?

I think it would be cheaper to just buy a new factory braided fuel line (I think that's what you have messed up?)

the braided line is actually fine, the best i could tell, the hardline after the braided line was rusted through and leaking gas. i didn't see a way to get the braided line off in a way i could attach new hardline. this is why i cut off the fitting on the sending unit, which i must have wiggled to much in the process, causing a bigger leak closer to the tank.all the hardline up to the filter is very rusted as well. i figured that i would risk damage to all the other lines along the frame rail (which are also rust) if i tried to tear out the old hard line.my plan was to run a 30 inch hard line repair section from napa from the filter back towards the tank and use high pressure line to connect the new piece to the sending unit.the new hardline piece is installed and so is the high pressure hose, i thought i had it fixed uptil i tried to start the engine and the sending unit started pouring gas on the ground.as of now, i have the tank on the ground, a new sending unit to install, new hardline to the filter and about 7 feet of question mark between them.

So why is the new sending unit different than the old one? The old one had been cut? cutting it may be the cleanest solution, but maybe you are worried about leaks this way. Is there not a sending unit available that works as-is?

What about getting the line that normally attaches to the EFI sending unit from a junkyard? This will have a hard-line you can cut and attach your hose to. I think these fittings were common between many different vehicles. Make sure you use a good brown O-ring. They may even have a "repair line" in the HELP section at your local parts store with the very fitting you are looking for.
