Replacing Hard Line From Accumulator to Filter

[kings1527]

Is there an easy way to replace that line without lifting the body from the frame or am I asking for serious trouble?

The goal is to make changing the fuel filter a more simple task because the elbow fitting at the bottom of the filter with the hard line's press fit into it drives me crazy. I usually end up disconnecting the main line from the distributor and ultimately unthreading the filter at the elbow and leaving the hardline connected to the elbow.

I'm considering a stainless braided line from accumulator to the filter from a vendor but A) it's a larger diameter so I'm not sure about installation and B) not sure if it'll change anything with the fuel/rest pressure but I seriously doubt that.

Thanks.

Get the new elbow from DPI. I just installed it and it works flawlessly. I couldn't get my stock elbow to stop leaking. The DPI one, went on smooth and tightened with little effort. http://www.deloreanindustries.com/27-fuel-filter-kit/

Thanks for that. It looks like cutting the hardline is required. Do you have pics of the install and the setup? I'd love to see what the overall job looks like.

You do have to cut the very end of the hard line to remove the compression fitting. Just use a small Pipe cutter, I got mine at Lowes Hardware. This also cleans up the end of the line because mine was no longer a "O" shape from being compressed.

Install the fitting into the filter, It has a sealing washer on it, Then when you get under the car make sure the bracket is installed on the filter, slide the new compression nut on to the hard line mate the 90 fitting and the new style compression fitting to the line. note, this new one doesn't fit over the line it fits against the end of the line. Then tighten. I have read how the stock 90 fitting you seem to need super human strength to tighten. This one you don't, or at least I didn't. I got it tight but no where near as tight as the stock one that I attempted to put back on and it just leaked.
Once tight, Hook up your upper line and make sure that is good and tight. Then reinstall the bracket to the frame. TEST FOR LEAKS!! I ran my car for 5-10 min in the garage then shut it off, then repeated, before it took it for a short drive, then home, checked it again, dry as a bone.
I will Take some pictures for you this evening. so you can see the final install and how much line had to be cut off. It was less than a 1/2 inch.

Thanks for the great writeup! And if you have time for some pics, that'd be awesome.

I apologize its not the best pics. but you can see the new 90 installed and it was 3/4" of pipe I had to cut off. Only because the compression fitting would not come off the hard line. Whole job took about 30 min. if you need any further pics let me know.

Thanks for taking the time to post those pics. They explain perfectly what the setup is like and I'm sold. Thanks again!

No problem! Glad I could help.

Did you have to use teflon tape for any of the threads? I'm in the middle of this job (just cut the fuel line) and want to make sure I do this right the first time.

No, I didn't use any Teflon tape. The only place you can use it is the fitting from the elbow to the filter, but that has the sealing washer on it too.

No tapes or sealants are required. Install our updated fitting configuration dry.

Josh, rookie question but I want to make sure I do this job correctly the first time for obvious reasons. With the compression sleeve, am I to follow Picture A or Picture B's orientation?

Pic B

[Delorean Industries]

B is correct. Thanks for pointing that out Ryan.

[kings1527]

Great, thanks guys. That's what I thought. Mine fell out of the compression nut when I was moving things around before I could see the proper orientation.

And one other clarification: the compression sleeve is reusable, correct? It doesn't act like a copper crush gasket on the oil pan that needs to be replaced after use?

That I am not sure of......, Josh?

I have the same question. I've had to remove the elbow a time or two while experiencing some fuel filter problems and want to make sure that the compression sleeve doesn't need to be replaced after use. Anyone know for sure?

I stumbled on this thread while trying to figure out how to tighten my elbow fitting to stop leaking.
I figured the elbow from DPI will be my best shot but I noticed 2 “different” elbows. (1) below is the kit with the elbow and fuel filter. (2) below is just the elbow. I think the elbow is the same elbow as in the kit, but have nothing that confirms that. Does anyone know?
