Does anyone make the fuel lines from the intake to the fuel hardline? I believe they are 3/8" and 5/16". The hard lines are for a vortec 350 ('99), so are the hardlines the same as the 99+ gen3 engines? I am helping a friend put a LQ4 into his OBS tahoe and this is the last part that is holding us up. He needs the fuel lines to go from the LQ4 rails to the OBS hardlines...

 

You can do it with AN line. Using one of the factory style fittings and a compression fitting.

 

I think he would rather have someone make some for him. He has tried S&P but they have gotten it wrong twice already.

 

they are not that tough to make...**** even i have done it and the truck has not burnt down yet.

 

You can get the fittings from summit. 14mm blah blah on one end with 6an on the other, then a length of line, next fitting is -6an on one end to quick connect. Same thing for the feed line,m just a 16mm blah blah instead.

Blah blah = the rest of the name i cant remember.

^^One of those will adapt the return, the other will adapt the feed to -6an

Basically just find how long of section of AN hose you need, then add those to one end, quick connects to the other. One disconnect is 3/8, the other 5/16

just go to your local napa or a store like it..they will make you the piece of hose you need right there..they have the fittings that clip onto the nbs fuel rail, where the flex line is stock...they put those fittings on some fuel line plastic hose, and then you do a compression fitting on the other end. cut off the old fuel lines and connect them...i just did this on my tahoe and it works just fine...had them on for a month and no issues...only cost like 35 bucks

 

well damn thats saying something

Are the fittings on the fuel rails removable?

 

Im assuming those fittings are for the hardline, right?

 

I edited that post with the quick connect links.

Ya, the 14mm and 16mm are the screw in fittings to the vortec lines, that adapts them to 6an.

Those are all what I used when going from my vortec 4.3 lines(just like the v8) to the marine intake(which has the same quick connects as the LS stuff)

 

Ok so this is all he would need:

1x 9894DBHERL
1x 9894DBJERL
1x 640850
1x 640860
2x 658490

Total is about $100 on summit
