I've got a Blox intake manifold and BDL fuel rail, and I'm trying to put in my ID 1000s. Just want to make sure I've got it right. I took off the fat washer on the bottom of the Precision and put it on the ID. There is also a hard plastic washer (no pic) that sits in the manifold then the fat rubber washer sits on top of that, do I need to use this or no? Thanks for the help.

 

One thing I can tell u is I took the o-ring off my id injectors as I didn't see them doing anything beneficial. I've used the fatter/taller seals that goes in the manifold.

 

Im assuming My gram injectors are the same size as These ID's. They fit like dick with just the OEM rubber base o-ring that goes in the manifold. I had to use those optional plastic rings that go under the rubber ones. Or from what i understand SOHC ones are larger and you can just use those without the plastic rings.

 

Normally you just drop them in as is. a few people that have used the stock manifold seal, the big rubber part, have had the injectors not sit far enough into the intake ports. this causes fuel to stick to the intake runners and stick/pool.

you'll need to test fit them both ways to see what works.

it's also worth noting that using just the o ring included with the IDs has caused fuel leaks occasionally, mostly under high boost pressures.
