GM Bob :

Hello my name is XXXXX XXXXX I can help

GM Bob :

Can you see the connector?

Customer:

Not the ones in the front but I can on the fuel pump its self and cant get those off as well.

GM Bob :

is this what you have

Customer:

It appears to be I have seen many videos on how to remove them and the only difference is that the videos make it look like there is a bigger tab to squeeze than what I have.

Customer:

I feel like I am doing something wrong because all the videos say 30 seconds to disconnect and I have spent 3 hours. Either I am doing something wrong or they are full of it on the time.

GM Bob :

Can you turn the connector on the line or is it seized

GM Bob :

They build up with rust in them

Customer:

I dont thin so, I see alot of rust around the fuel pump lines. Thoses I know I cant move, havent tried turning the front lines.

GM Bob :

can you do this

Full Size Image

Customer:

If you can give me 5 min I can go see if I can turn the front ones.

GM Bob :

spray some wd40 or some thing to break free

Customer:

Yes easily to the pump lines. If I get the pump lines off will I then be able to remove the tank to get the pump out.

Customer:

Or do I need to remove the front lines to get the tank out.

GM Bob :

The line may be long enough to drop the tank a little. The last one I had I had to replace the fuel feed line

Customer:

Thats not good thats about 100 bucks a line correct

GM Bob :

Yes or more

Customer:

great.

GM Bob :

But if it don't look good it may not reseal and you will have to drop the tank

Customer:

what wont reseal

GM Bob :

the fuel line it may leak gas

Customer:

thats not good let me go and try the wd 40 and air and see what happens.

GM Bob :

ok

Customer:

wd 40 and air didnt work so I guess I will have to replace the lines as well. Is it just best to cut the poly lines around the connections in the front.

GM Bob :

I would just cut the plastic line 2-3 inches from the connector. You will need some thing to grab when you try taking it apart.

Customer:

ok thank you for your help.

GM Bob :

Thank you for letting me help. Sorry that you will have to replace the line

Customer:

its ok I guess in the long run its better to be safe than sorry

GM Bob :

Don't want to drop the tank again for a leak

GM Bob :

Please don't forget to rate me

Customer:

no not after i have already spent 5 hours trying to get it out already. Thanks again.
