Injector question on 96 Blazer. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

krue · 03-04-2010, 10:12 PM

While replacing the fuel pressure regulator, two of the injector hose clips broke. I need to know if I can jy the hoses, the injectors (if the hoses can't be removed and replaced) or do I need to buy new (really don't wanna have to do that on a motor with 250k on it). I kinda need to know quickly so any help would be appreciated.

I believe this is what you are talking about:

They are not cheap, for what it cost to replace 4 of the injectors (I know you said you only had 2 broken ones) you might concider upgrading to the newer MPFI design. This is a direct replacement, not necessarily a performance upgrade, but many have noted better idle, fuel economy and better overall drivability. If you have not run fuel through your new regulator, you can return it as the newer injector assy comes with a new regulator.

since the injector hoses have been in the same position for 10 years worth of thermal cycling they tend to develop a memory. the clips are designed to hold them in place during initial assembly. I have ran across this a few times and at the most zip-tied the tube to an adjacent one as an extra measure.
