modified fuel feed and return fittings question

[jbmjbj]

Okay, so I posted a question a couple days ago about replacing my stock sending unit since the lines are kinked, but now I am thinking it will be more cost effective for me to just weld a couple of bungs on the top and attach my system in tha way. My set up will be -8AN feed and -6AN return, but right now I will be forced into using the stock lines (both feed and return) for a couple more months. What fittings will I need to get to go from -8AN feed bung to stock feed line, and from the stock return line to a -6AN bung? I realize the feed is overkill, but not for what this thing will b e pushing when im done and I dont want to reove and re-weld different fittings when that time comes.

Not sure what you would need to go from AN to stock line but why not just cut the hard oem line and bridge the gap with rubber high pressure fuel hose. Also when you are ready for the AN line use bulkhead fittings.

From what I can see by searching, bulkhead fittings don't work on the 2g because it would drop the fuel pump too low in he shallow tank

Hmm thst may be true i have never had a 2g.

I seriously doubt there are any premade fittings that properly fit the metric threaded, inverted flare flare fittings of the stock lines to that of a standard an fitting.

That would be the lowest cost solution to your problem. And then allow you to save more funds for doing it the way you want later on when you need too. And so long as you use good high pressure fuel hose rated for that use, and good clamps I don't see anything wrong with that solution. ( Heck I did it once with my first DSM)

wouldnt the pressure of the system blow the hose of the hard line unless it was flared?

Like I said I did this before on my first car, It's obviously not the optimal solution and I'm not officially recommending anyone do it. However I did it and it worked fine. I used high pressure fuel hose and two worm gear clamps on each side.

That said I didn't cut it with a pipe cutter either, I just cut it which mashed the pipe in, which I then opened back up with a screwdriver which likely flared the ends of the pipe a little and gave the hose something to grab onto. All I was saying is that it's the lowest cost solution to the problem. I wouldn't be worried about doing it again if I had too, however I will never officially recommend anyone do such a fix. Do it at your own risk if you want.


If your worried about it but want to try it you could maybe try bumping the base fuel pressure high as hell to see if it holds without the car running, just turn the pump on and raise the fuel pressure real high (say 10psi higher than whatever it would be at peak boost) and if it holds.. eh i'd say your good for a temp solution.

Thanks, that's what I figured, it would get me home, but not down the track :-)
