I picked up some MSD 72lb/hr Injectors and I know previously others have posted to use stock top and bottom o rings. I put a stock oring on the top seems loose in the fuel rail, is 2 stock orings needed at the top? Just one. Set up is a Golden Eagle Fuel Rail(haven't picked it up yet) JG/Edelbrock IM on a GE sleeved B16A. I fitted the injectors in the stock fuel rail. Any help is appreciated. TIA.

you can either use two on the top or go with larger oring.. You can get the oring sfrom any AC supplier.

Thanks Viren. Always there with a quick reply. I was the guy at VA NOPI event asking for some MSD injectors, you didn't bring any. Sorry for your troubles that day. I wanted to chat with you but you were busy and I stay outta peoples hair during important races like this. Thanks again. And bottom Oring stock as well?

stock black oring on the bottom and stock green on the top

I used the stock o-ring on top (rail side) along with another o-ring from Napa below it......it is a little smaller than the stock one is, but it is a fuel safe o-ring. The second o-rings prevents the stock one from sliding down when you put it in the rail. Works real well.

Thanks for all the help guys. Anybody remember the inside and ouside diameter of the orings you bought and used. I've been through Pep Boys mess of Orings takes forever.

I just took the stock ones that came with my AEM rail and sized them up with ones at Napa that had the same ID. They actually have a slightly smaller OD...but like I said, they just prevent the originals from moving when you put the injector in the rail. Oh yeah, use some motor oil to lubricate the rings and prevent them from ripping.

i used the small stock black orings, they seemed to seat ok. is taht allrigt?

Farnsrocket

Should be OK.............you''ll know when you start your car.

lol, that'w what i am afraid of. are the small upper balck o rings a different size than the green ones? maybe i got the wrong ones.

Farnsrocket

Man, I am not sure ....where did you get them? When you put the injector in, is it tight? Does it take a little effort to put it in? The green ones I have came with my AEM fuel rail.........I think my stock injectors had green ones too.........I forget. Sorry

downpipe

i got them from A+H motorsport, they sell all honda stuff but cheaper. they didnt take too much effort to push in....the rings slid down towards the bottom when i slid them into the rail. thats why i am a little concerned. so they are straight from honda but maybe they are the wrong ones? maybe i'll pick up some green ones, the green ones were on my old rc310's that i sold, that i am sure of. i was expecting green ones actually. how far in did you inectors seat on the bottom? sorry i'm rambling i'm way overtired. i'll catch u later, thanks farnsrocket.

Farnsrocket

my green ones slid down too, until I put that second oring in there.........I will take a pic of my injectors in the rail...........where did you get your injectors???
