Can anyone confirm what lb injectors are used on an 03 MCX?

I wanted to follow up on this thread to hopefully help the next guy out. I pulled my injectors and they are GM 17124187 24lb. injectors. I am replacing them with a set of Bosch III matched flow injectors.
When I was disconnecting the crossover lines to the fuel rails one of the brass nuts split. Only thing I can think of that would cause this was that it was over tightened during installation initiating a crack and when I broke the nut loose it let go.
From researching online the Indmar part# for the line is S786129. There's not a lot of places that I can find to buy this part from. I was going to replace both lines with SS braided lines, but read that solid crossover lines would cause a "hammering" effect to the fuel flow. Is there a known source for finding odd ball Indmar parts like this?

So are you saying that S786129 is a good part number or not? IE that part number will cause the hammering effect?

S786129 is a good part number that will not cause the hammering effect. It's built similar to a hydraulic hose - rubber hose with SS ends crimped on each end of the line. The rubber part of the line is supposed to dampen the hammering.

Thanks for the links. I snatched one new off of ebay this morning that was in the states. I was just curious if it was somewhere forum members bought Indmar specific parts that had reasonable prices. Most of the parts I've found seem like the people selling them are trying to put their kids through college off of the profit they make off of them. I do understand that some parts are hard to come by and that's just the nature of the beast.

@bdiesel how are those fuel injectors working out a couple years later? I just pulled the injectors from my 1999 205V. They are 17121068 and from what I can find online seem to be 24lb also. Notice much difference moving from the OEM to Bosch injectors?

Just closed out three summers with the Bosch injectors without any issues. I didn't notice any difference between the two, but I changed them over the winter so I didn't have a direct comparison.

That's awesome! Did you have to do any modification to get them to fit? On some other threads there has been some discussion of needing to chamfer one of the receiving surfaces to get superseded OEM injectors to fit. Do you remember what model yours were (are all BoshIIIs the same?) I know you mentioned they were 24 lbs/hr.

I didn't have to do any modifications to make then fit. I pulled an injector & shipped it to where I purchased them. Unfortunately I can't find the part numbers of the injectors I purchased. I'll keep looking & if I find it I'll post them.
