Bit of a problem:

Ok so ended up buying some 1000cc Bosch injectors from Goleby's Parts, they helped out and I ended up getting them with the short 11 mm adapters to step down from the 14mm top o ring to the 11mm of the fuel rail

Having a problem getting them to seal against the head though. I pulled the stock injectors out, pulled the large rubber o ring piece off the stock injectors out (one was wedged in the head, its a large bit of rubber, about 4mm in length, and about 20mm in diameter with a 3mm wall, looks like an o ring on steroids), cleaned the holes out, fitted the injectors with the adapters on top into the rail and then screwed the rail down into place. Now I have a large air leak, could hear the engine sucking air in past the o rings at the head, sprayed some throttle body cleaner down to confirm.

So I pulled the rail again, and then slipped the stock large rubber o rings (that pushes against the stock injectors and seals against the head) over the nozzle tip of the 1000cc injectors. I then screwed the rail back down and this has helped it seal a bit better, but it is still leaking.

I spoke with Goleby's Parts and the gentleman I spoke with had to modify the stock o ring head seal on his Toyota Paseo with a 4efe engine, cutting a bit out of the center of the rubber so they would seat properly

Going to give this a go tonight, hopefully this fixes the problem

Anyone every had a problem trying to get injectors to seal against the head?
