Ok so I'm in the middle of my motor swap I made my fuel lines I'm gonna make some type of fast fuel system so I started with half inch lines from the tank but was gonna wait on the fast fuel stuff till a later time but I made a draw straw cause also like I said I was in the middle of a motor swap but anyways I have half inch lines to my lift pump for the min but when I was pumping my stock lift pump by hand it wasn't bringing up the fuel so I started the truck and it ran for a few seconds then what was left in the injection pump ran out but it started bringing up the fuel so I cracked my lines till there was fuel closed them up the started the truck again took a little bit to get her started and I run the truck for about 3 or 4 min shut her off and she wouldn't start back up I have clear fuel lines and I can see the fuel but it seemed like I kept having air right befor the lift pump but not at the tank and all lines are tight what do u all think I'm doing wrong here or what should I be doing that I'm not doing????

 

go back over all your lines and make sure none of them are cracked

 

Can't find any leaks or cracks

 

how about the drawstraw? you said you made it, out of what? does it go all the way down, and the dummy question how much fuel is in the tank?

 

I'm thinking I may have split a flare I'm not sure I'm gonna look more tomorrow in the day light btw I put 7 gallons in

 

Did you put in a new lift pump? I did when I did my conv. and the new pump had a diff. thread port than the stock pump and I put a hairline crack in the housing when I put in the old fitting and it sucked enough air to do what yours is doin, and it never leaked fuel. Best of luck, I know how frustrating this sh@t can be!

 

I also changed my liftpump awhile back and I guess I over torqued my fuel line and cracked my liftpump also and didnt know it but it did do basically the same thing.I got a different pump and it fixed my problem.

 

It end up being a flare I messed up on so I cut it off and started over now it works perfect so now I'm happy I can get back to other things so thank u everyone for the help
