my truck has hard lines running from the fuel rail, back to where the x-case is located. the lines have male 16mm and 14mm fittings on them (look like brake line fittings). my fuel tank had identical hard lines coming out of it, with the same male 16mm and 14mm fittings.
stock the truck had soft rubber lines running between the hard lines. these soft lines had 16mm and 14mm female connectors with clamped (air cond.) style fittings, which clamped them to the soft lines.
the soft lines are pretty much shot. i can order some, but i’d rather go AN.
so i bought AN lines an fittings to run where the soft lines ran. but there is no AN fitting with a 16mm or 14mm female tap. So i have 2 male ends. 16 to 16 (feed) and 14 to 14 (return). and i was looking for a female/female coupler fitting to go in between. but there is no such thing.
what this guy offer to do was, take the old fittings off the soft lines, hack the clamped part of the connector off, and weld 2 female ends into a coupler.
the easiest way out of this is to find some stock soft lines, and just replace them. which is probably what will end up happening, if i cant find another way around it.
i have had them weld a lot of fittings for me and have worked flawless. i wouldn’t hesistate to have them weld a fitting for you. lot of times can be made for less than a new fitting.
nice
double check the black hose. it seems more difficult to make it seal. just from experience. so when you fire it up just double check all the fittings.
do not use tape on AN fittings. it is fine with a pipe NPT thread but not on AN fittings. the biggest problem is the attachment of the hose in the fitting where i have seen leak the most.
look into german cars. most are 12mm, but seen some benz w/ 14mm.
cut the hard lines on the sending unit, and replace them w/ the -an end nuts. then you can run an straight to the sending unit. those sending unit lines should be able to flare just like regular fuel line.
last option i see is do away w/ the hard line, drill and modify the sending unit and use bulkhead fittings.
