Hello, cal you tell if any hoses hooked to it?

Customer: replied 1 year ago.
no hose/s connected to it...kinda looks like it might screw in, but not sure...let me see if I can get a better picture...
Expert:  Randall C replied 1 year ago.

odd , are you sure? Is it in the fuel rail, I am pretty dran sure I know what it is, but no hoses at all to it is odd

Customer: replied 1 year ago.
no hose...looks as if goes on end of fuel rail...
Expert:  Randall C replied 1 year ago.

ok, the only item that would be in that location screws in in the fuel pressure regulator, The round end is actually a rubber diaphram inside that controls fuel pressure, Nothing else like this would be in the fuel rail and yes,, the regulator does screw into the fuel rail

Customer: replied 1 year ago.
is the part leaking the only thing needed to fix this?...or does the whole fuel pressure regulator have to be replaced?
Expert:  Randall C replied 1 year ago.

it is the fuel regulator, it can start leaking at a seam etc, It unscrews, its all one piece so the only repair would be a fuel pressure regualtor, no other parts, the regulator will have a seal on the ed=nd so remove and install new

Customer: replied 1 year ago.
all of the ones I see online look to have places for hoses, but as I said, there are no hoses connected to this one...can you give me a link where to buy one like I have?
Expert:  Randall C replied 1 year ago.

i understand but screwed in the rail has to be the regulator, have you tried removing it? maybe the nipple broke off it and you just cant see it

Customer: replied 1 year ago.
no sir no nipple/s...looks like maybe it's a dampener or something?
Customer: replied 1 year ago.
hello...is it possible to repair, clean or do something to this fuel injection damper?...
Expert:  Randall C replied 1 year ago.

sorry for the delay, I have nothing on my end repair wise and have?? been doing this a a tech for near 38 years, Agree, it may be a damper what they would call a pulsation damper but nothing at all repair wise and I cant remember all of them so,, everything I have on my end is fuel pressure regulator, so,, can you send the full VIN and maybe I can find more
