80LS1T Posted January 5, 2004 Share Posted January 5, 2004 I am thinking about upgrading my fuel pump and fuel lines to accomidate the LT1's fuel needs. I dont think I'm having any fuel delivery problems but I would still like to get a new pump and some new lines. I have 3 questions... 1. How do you attach those "compression" style fitting that are used with steel braided hose, to a hard line? Another words how am I going to connect them to the hard lines on the fuel rail? I have those quick disconnect fittings on it now with rubber lines that are connected to the original stock hard lines.(Not the safest thing in the world I know, thats why Im upgrading! ) 2. What fuel pump should I go with? I can still use an inline one like the stock one right? 3. What size of line should I use? I might upgrade later with some engine parts so I think 500HP would be the max for this car. Thanks, Guy Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 5, 2004 Share Posted January 5, 2004 Guy, Here is what I'm doing: I am using the quick connect fittings (OEM Z28). I then use fuel line with hose clamps over those (they have ribs on them), which are connected to my aluminum fuel line. I'm using 3/8 feed and 5/16 (I think) return with the MSD inline pump, like this one: Tim Quote Link to comment Share on other sites More sharing options...
80LS1T Posted January 5, 2004 Author Share Posted January 5, 2004 Where did you get that MSD pump? Doesnt the 3/8" seem kinda small? What size is the fuel line on a Z28? Guy Edit: Never mind I just found the pump on summit's site...#MSD-2225 $76.95 Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 5, 2004 Share Posted January 5, 2004 Got the pump from here: http://store.summitracing.com/partdetail.asp?part=MSD%2D2225 The feed line on the Z28 is 3/8, or maybe the metric equivalent. Tim Quote Link to comment Share on other sites More sharing options...
80LS1T Posted January 5, 2004 Author Share Posted January 5, 2004 So Tim, you just have a small piece of rubber fuel line in between the hard line and the pump? Is there a way to connect the hard line to the pump? Guy Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 5, 2004 Share Posted January 5, 2004 yeah....with rubber line. Tim Quote Link to comment Share on other sites More sharing options...
BillZ260 Posted January 12, 2004 Share Posted January 12, 2004 So I DO need a small rubber jumper line between the pump and the hard line? I don't want to run the hard line right into the pump, correct? Quote Link to comment Share on other sites More sharing options...
mas28O Posted January 12, 2004 Share Posted January 12, 2004 You can just run a 6 an hose to the fuel rail. All you need is a quick disconnect to 6an adapter. Quote Link to comment Share on other sites More sharing options...
80LS1T Posted January 13, 2004 Author Share Posted January 13, 2004 Where can you get an adapter like that? I havent seen them in the summit or jegs catalogs? Guy Quote Link to comment Share on other sites More sharing options...
