I cant tell by looking, but I do know that the new spider is a big upgrade from the poorly designed original. somewhere on this forum there is posts on this subject

 

Heres an old and new picture. I believe the spider is a common problem

 

I shhould be able to test the fuel pressure with it disconnected right? I think i have to block off the fuel return side, and put the pressure gauge on the outgoing side?

 

well its a shame in my opinion that GM Chevy just doesn't offer a recall for that part. Seeing as they knew it was a problem so they introduced a fix for it.

 

I may just order the Delphi FJ10565 injector through an ebay seller, amazon wants over $14 tax, bring the total price to $191 .. pffffsshhhh!! I will probably increase my price of the truck for the work. But an upgraded fuel system compared to other blazers on the market (who knows if they done it) does sound like a good deal imo.

 

If u replace the spider u should ABSOLUTELY increase ur asking price. After getn the new and improved spider put in as well as having to get a new fuel pump for the 4th time in a repair shop, it costed us almost $900 for parts and labor and he didnt even charge HALF of labor costs. So for sure, up that price

 

True, basicly a whole new fuel system
