Gas tank

**Dacton1985** · 10-05-2016

What would be the best way to drain my gas tank? It's a 07 gp gxp 5.3l

I'm not familiar with the return less systems but if the pump is functioning could you disconnect the fuel filter and run a hose from that to your gas can?

**Dacton1985** · 10-05-2016

Damn good idea

**stealthee** · 10-05-2016

Would be a good idea if there was an external fuel filter.

Just so happens, I went over this yesterday w/ a couple guys, check out "fuel pump shutoff" in general tech discussion...

Is the fuel filter in the tank on these then? Like I said not familiar with them.

**stealthee** · 10-05-2016

Yes, 04+ doesn't have an external fuel filter. Only an in the tank filter that is not serviceable.

Thanks cheatah.

**cheatah faheatah** · 10-05-2016

No prob. I'm going to try the Schrader valve/ jump fuel pump relay trick this weekend...P.S. I don't know how to insert a link into a post yet, so i'm glad you found it. I clicked on "fuel pump relay" in my post to you, and it went to a shopping site LOL...E.......

Well then I'm an exception, because I've definitely got a filter on the fuel line, outside of the fuel tank.

**stealthee** · 10-05-2016

I actually questioned myself and couldn't remember if 04 still had an in line filter or not.

**WarStryker13** · 10-05-2016

Mine's a weird one for sure, it's got a lot of random crap that it shouldn't. Lol

But I know that there is references for fuel filters that are inline, and not the return style, in the FSM for 04 and I've found them on RA.

**Dacton1985** · 10-06-2016

Good question on how to jump out the relay. Wonder which ports you place a wire in

**cheatah faheatah** · 10-06-2016

I'm thinking it's a relay underhood. I can PM you when/if I figure it out, if you'd like?

The 04 and 05 GT, GTP has an external fuel filter. The 05+ GXP does not have an external fuel filter like said above. also the 06+ Grand Prix does not have an external filter

**Dacton1985** · 10-06-2016

Yeah the relay is under the hood and that would be cool cheatah

**stealthee** · 10-06-2016

Appreciate the correction. Like I said, as I typed that I was questioning my memory. LOL

Alright, I'm on it. I think I'll post a "how to" if it goes good, and safe. Ya know, gas+spark=not good outside of engine. I found a couple youtube vids, but nothing specific on GP's....E..

**Mitch R** · 10-06-2016

Somewhat off topic but your post about spark and gas outside the engine made me think of it. I was replacing my fuel lines the other day and the needed to replace one of the nylon quick connect fitings and the parts salesman tried to tell me I could heat up the nylon lines with a lighter. I was like no I like the way my face looks. I decided to use a nylon compression fitting instead.
