xmission 9 Posted October 18, 2020 Report Share Posted October 18, 2020 I just finished getting this worked out, and I thought I would post this here in case someone needs it in the future. On the pressure regulator side you need one of these https://smile.amazon.com/gp/product/B003CGSUL0/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 It is a GM EFI to An6 male straight adapter. Note that you want a steel one, because you will need to heat it in order to bend it. The engine bolt right below the fuel pressure regulator interferes, so you have to modify it. I broke an aluminum one trying to heat and bend it. I drilled a 5/16" hole in a block of aluminum, heated the middle of the tube, stuck a big socket loosely over the threads, and bent it slowly by hand. an AN6 45 to hose finishes this end. On the other end, you will need an AN6 straight to hose fitting, and this: https://smile.amazon.com/gp/product/B000CNB8NS/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 It is 14mm That's it. FYI the output from the pump is the same type part, but 16mm in case anyone ever needs it. https://smile.amazon.com/gp/product/B0049D7ZSO/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 Hope this helps someone. It was a pita to get the right parts figured out. Dan Quote Link to post Share on other sites
Erikl 10 Posted October 19, 2020 Report Share Posted October 19, 2020 Can you post a pic of the finished other end? Thanks or the write up. Great info. Quote Link to post Share on other sites
Erikl 10 Posted October 19, 2020 Report Share Posted October 19, 2020 Also, did you use a full on Oxy Acetylene torch or just propane/MAP gas for the bend? Looks like you are pretty well set up and have access to the former. Quote Link to post Share on other sites

Looks like you are pretty well set up and have access to the former. Just a propane torch. I was afraid I would blow it out with a real torch. It took it a bit to get it hot enough to bend, and never got red hot, but it worked out fine. Note: I thought I posted this earlier, but I don't see my reply. Hopefully I'm not posting the same info again A little more info. Here are the end to hose fittings: 800106ERL - straight to hose Amazon doesn't have this one for some reason 804606erl - 45degree to hose https://www.amazon.com/Earls-804606ERL-Swivel-Seal-Hose-End/dp/B0002M9GZ6 I've also posted this on the turboesprit list so that it'll be out there when someone needs it. 1 Quote Link to post Share on other sites
xmission 9 Posted October 19, 2020 Author Report Share Posted October 19, 2020 That is just blue tape on the fittings to keep the wrenches from scratching them. I haven't climbed back in and removed it yet. 2 Quote Link to post Share on other sites
Erikl 10 Posted October 20, 2020 Report Share Posted October 20, 2020 Thinking about this some more last night. Changing these lines to AN woudl allow you to easily add an in line high quality FPR and a fuel pressure gauge. Nice parts to have if upgrading/modernizing the turbo.

jfitz981 13 Posted October 29, 2020 Report Share Posted October 29, 2020 This is great information much appreciated. Thank you. I came across a 3/8 GM Quick Connect Male BLACK Z148N -6AN 90°: https://www.amazon.com/Adapter-Fitting-Quick-Connect-BLACK/dp/B07ZHJWSJY Would you think this would work instead of bending a straight adapter? Last question, how much hose would be needed? Take care, Jason Quote Link to post Share on other sites
xmission 9 Posted October 29, 2020 Author Report Share Posted October 29, 2020 (edited) You'd want to try this one (it's 5/16" instead of 3/8"). It looks like it might be a bit too long before the bend, but I would definitely give it a try. Worst case, you might have to pull off the fuel pressure regulator, stuff that in, and slide it back on if there isn't enough room to stuff it in normally. https://www.amazon.com/BLACK-Z147N-Adapter-Fitting-Connect/dp/B07ZHJGX7L/ref=psdc_346821011_t1_B07ZHJWSJY Funny, I couldn't find anything like that when I was searching. I would get 5 or 6' of hose just to be safe. I used plastic braided, as I saw a lot of folks say that the steel acts like a saw when it moves around. This is what I used. Plenty for $22 https://smile.amazon.com/gp/product/B00LSH6GRA/ref=ppx_yo_dt_b_asin_image_o03_s00?ie=UTF8&psc=1 Edited October 29, 2020 by xmission 1 Quote Link to post Share on other sites
jfitz981 13 Posted October 30, 2020 Report Share Posted October 30, 2020 Much appreciated. I am getting all the parts together for the winter Esprit projects so with the age of my fuel lines, this is a very worthwhile upgrade. I too will go with a non steel hose on the return line as I do not want issues with the hose potentially sawing through anything. I am also taking this opportunity to upgrade my fuel pressure regulator to a Aeromotive 13109 B A1000 EFI Adjustable Fuel Pressure Regulator with a gauge. This info has been quite helpful!
