So.. one thing had bugged me from the beggining is one of the pumps I used had a completely different rattle to it and it's been in the back of my mind. I also did use the plastic clips and I'm wondering if they may have come off as well so I've been wanting to tear in there again and replace them while I'm in there with a high performance pump and use better steel clamps.



This is interesting because I'm not sure but this may be me you are talking about ! I appreciate you posting the research. I had no idea and never cared to really look into the fuel pump part numbers. I had been planning to change my pumps because on install one pump had a distinct rattle that bothered me (think I posted a video of the rattle -if not will do it today) and I also didn't use the screw steel clamps. For some reason when I think about the plastic becoming brittle and being under stress if overtightened it only makes sense they can split and break easily leaving the hose free to shoot off (pretty sure that's what others have mentioned) . SO... I ordered the twin walbro pumps from Lingenfelter. Not cheap but I feel much more comfortable with Walbro pumps from them. Will post again when they come and I tackle it. Will also change my fuel filter again too.

Yes Mike, it was you that I was referring too. Just didn't mentioned your name because I didnt want to imply that "I think you ordered the wrong part"
I have a habit of researching and double checking parts #'s and applications. Although I might not need fuel pump replacements in the near future, I did order the LT5 Denso pumps back in April. As mentioned they are on Natioal BO, but as of late last week, my order finally got submitted. So it seems like they are in production.
Will be anxious to hear your report on the pumps you just ordered.
Glad my earler post helped.....
