Hey Im new my name is randy. I baught a 99 blazer 4x4 guy said it had a new fuel pump put in and after wards it is now hard to start in the morning i have to poor a little gas in the throttle body and when its warm turn the key on and off a bunch of times. I noticed when i pulled the tank that the black sensor seemed loose and the middle line on the pump had no clip to hold it in. so i cleaned the gaskets reinstalled the tank but while doing so i broke that sensor off i got a new one and it seems like it has a much tighter fit. before i this tank back up any other ideas? its got pressure on the big line it sprayed all over me when i took it off? Please hurry i need a ride lol thanks to all that can help!!!!

 

The fact that you sprayed fuel means nothing. Use the steps in 96+ Fuel System Diagnostics to check your fuel system operation.
