Hey guys, I had a question about the Fiveomotorsport injectors. I did a search and saw that the injectors that guys on here had bought from them worked extremely well, so I bought a set of my newly acquired black 91 GTA with the 350 L98. I bought the injectors set that they had listed on their website as the OEM replacements for 88-91 corvettes. I was expecting them to send me the D9B injectors with the pink tops but when the package arrived, they were yellow top injectors with the part number D5B. Doing a search on here, I find that D5Bs are 19lb injectors??? So I send an e-mail to Bruce to see what's up and he says that I have the correct injectors and that the D5Bs and D9Bs are completely interchangeable? Is this true? I'm getting ready to get my car back on the road and I really can't afford to blow my engine due to a lean condition... what do you guys think?

 

I dunno, we got the Pink Tops. They will be for sale in 2 weeks if you can hold out lol. Were moving to 42's

 

If you are certain that you have the 19's, return themand ask for the 22's. If they will not do that, return them for a full refund and get a pair of 22's off of ebay.

 

From what I see at Ebay the yellow ones are 21.5# and the pink are 24#

 

yes i recomend you do your research and ask for the exact part number........ I have met bruce before and he seems reasonable but can't know it all. I am very happy with the walbro pump he sold me.

 

NEVER buy injectors off of Ebay,,, many many horror stories about people buying injectors from Ebay. Poeple have gotten a mix of 19s and 22s, only 6 working injectors, only 7 not 8, injectors having broken connectors.

You need 22 #/hr injectors, buy new ones from a trusted company, you should be able to return the 19s for an exchange or refund.

 

From five0's web page the d5b(yellow top) and d9b(pink top) are interchangeable. IE; they have the same part # crossover and application. Link

I've had good dealings with Bruce/ five0motorsports.
