Hey all - I wanted to share some of my data with the group, since it took me a little while to find this information, and I wanted to update older information out there and pay it forward, in the hopes that it'll save someone else the time I spent.
I had taken last year off from boating for a lot of reasons, but coming into this season I could not get the boat to start, and recognizing that all but one cylinder was dry. Since my boat is a 1996 (with 600 hours), and I've NEVER done anything fuel-wise, I decided to just go through the system and replace/update everything - mostly to avoid getting stuck OR having to do it later. And I wanted to share the parts I replaced (especially those that have replacement options where I couldn't find original stuff, or anything not rebuilt):
1.) Fuel Filters - Main filter = NAPA FIL 3481, filter near tank = NAPA FIL 3482
2.) Fuel pump (original I believe is Carter P60962, which is obsolete and no longer available). I used a Quantum HFP-706 from Quantum Fuel Systems (available on Amazon or via their website). Direct replacement with same threaded female fittings, exact fit.
3.) Fuel injectors - anything OEM is EOL - you can find refurbished out there, my engine had a mix of OEM and some replacement (I think Rochester may be the OEM company). I replaced with Accel Performance Injectors, #150820 (available on the Holley website), which is a 24lb/hr injector that I believe is factory spec, from what I could find. I did not want to deal with any retuning.
4.) Fuel Injector Pressure Regulator - Delphi FP10003, available on Rock Auto
Net, all pretty easy replacements, engine fired up immediately after priming the fuel rail (turn key and listen for pump, turn off, turn back on to fill the rail). Pretty easy to find YouTube videos on replacing the injectors for an LT1. Hope this helps save someone what I went through.
Pro Tip(s) - use fuel line thread seal, check for leaks, have an extinguisher handy for the first crank. Cheers!
