~short story:
Does anybody knows the dimensions (thickness, diameter, etc.) of the stock B18B1 fuel rail spacers?


~long story:
Engine misfired cylinder 3 and 4. So I decided to clean the fuel injectors.Noticed my new-used 1997 LS was missing 2 fuel rail spacers. Took off the fuel rail, ...started to rain..., third one fell-off and is stuck between the thermostat housing and intake manifold.
PLAN:
a) Tried the magnet, but it's made of plastic.................fail
b) small point, long extended flat screw driver...............fail
c) clothes hanger, modified with a hook........................fail
d) thin kebab wooden stake with duck tape in the end.....fail
......so I'm just planning to leave it there and custom make a spacer.

 

Take off your intake manifold duh :]

 

LOL.
I'll consider it as plan (g)

Tried Google, Acura Dealership online reference, Ebay, Amazon, and still can't get the numbers!
At least I found out the studs were: M6 x 22mm w/ 1.0 threading..........

 

I tried plan (d) again with modifications.

Here is what I have...
8mm thick, 20mm diameter, 7mm inside

 

The only part you need to worry about is the thickness. Outside doesn't matter and inside either as long as it's big enough to go over the stud. I just stacked washers for my fuel rail spacers.

 

A million thanks!
I went to Home Depot, bought the (14) 1/4 cut washers [$0.11/each], stacked it on two sides and left the middle deleted.... so far no leaks!!!
Again thanks, you are a genius! ^_^
