TBI injector ID

[Moonshadow]

Hi folks and thanks for having me. I am sorry if this has been asked before, please bare with me. I have a set of injectors on my 1999 Volvo Penta 5.0 GSI PEFS and the numbers on them are #25170301 can anyone tell me what they are? I was told brown/yellow but their isn't any paint on them. Is there any chevy number or color chart to go by?

yes volvo throttlebody systems run just under 30 pounds of rail pressure and those should be 55lb injectors afaik. if you used them at standard rail pressure you'd be more like 35lb or something like that. i know this first hand because people have tried running an automotive tbi regulator on their volvo and no starty.

104# @ 30ish psi and 61# @ 13 psi. The TBI I have came off a 405 hp 502 in a houseboat that was upgraded(downgraded IMO) to 6.5 diesel power.
