Im putting TPI in a TBI car. this should be sooo simple but it just isnt..


The factory fuel feed lines are male, 14MM and 16MM. Ill be using the feed as it is so no change there.

But the return line is gonna be different. Im using cold injector hole in the back of the fuel rail (14MM Female) to a 14MMmale ->3/8 NTP male for the regulator, then from there, 3/8 NTP to 8AN Fitting to my 8AN hose end. the hose will run to the factory Return line, a 14MM Male. problem is, i cant find a 8AN - 14MM male fitting.

In fact, i cant even find a 14MM - 3/8 NTP fitting for my regulator.

is there another way to do this? I found a 14MM - 6AN but im not using 6AN hose, and that wont screw into my regulator either.

I found a 3/8 NTP - 3/8 NTP malemale fitting that i could cross thread into the 14MM cold start hole, to get my regulator plugged in. but thats a bit ghetto.

I also could use that 14MM - 6AN fitting, then use another fitting 6AN - 8AN to make it connect to my 8AN hose end. but thats ghetto also.

 

I would suggest getting an -8an Male connector welded onto the back of the rail, that way you just run -8 from the rail to the regulator.

For the hard line on the car, you could put a male -6 to 5/16 compression fitting on there and then -8 to -6 reducer to hook the -8 line to the -6 on the hard line.

Is the only reason for going with -8 lines because of the regulator?

 

Where have you looked for the fitting? Any industrial fluid power suppliers?

 

No actually vader i was only checking aeroquip and earls and russells. I am going down to a hydroulic shop tommarow to see if they have what i need.

Zepher the regulator is 3/8 not #8, i wish it was -8 it would be so easy...

Its a bit confusings without seeing it. If i cant get the fittings real soon im just going to use a few "extra" fittings to convert over to what i need. i hate adding places for fuel to leak though...
