so i have a cosmo center iron that i used in my rebuild totally forgetting that the primarys are top feed. so i took out the spacer in the primary injector holes. well now i regret it and i want to run the top feed cosmo primarys. DOES ANYONE KNOW WHERE I CAN BUY THE SPACER TO PUT BACK IN SO I CAN PUT THE TOP FEEDS BACK IN. KEEP IN MIND THIS IS ON A COSMO PRIMARY FUEL RAIL. I am also not 100% sure that the cosmo primary injectors are top feed or not

 

is it the same as the FC?

otherwise post in the 2nd gen forum. Cosmo motors are a lot more common in 2nd gens.

 

no it goes in the hole to make it smaller in diameter

 

The Cosmo runs side feed primaries and top feed secondaries. Sounds like you are looking for the primary injector rails seals, they are the same as the FD, just call Ray at Malloy.

 

its hard to explain. say u take out the stock cosmo primary fuel rail and look at the end that the fuel sprays out and compare it to a stock fd. they are a different diameter i think. see there were these collars or inserts in the primary fuel bores on the iron its self that made the two bores smaller than that of a stock fd iron. its the darndest thing i ever seen, the only explanation is the privious owner istalled the injector collars into it like the ones they sell on rx7store.net. here is a pic of what i think it is that i had to pull out of both bores

The aluminum sleeves are from KG parts and are used with aftermarket top feed fuel rails.
