Report post #1 Posted 12/08/19 12:21 PM I want to replace the fuel pump in my FG XR6T, but the tank is around half full. Is it possible to replace the fuel hose where it comes off the pump with a hose going into a jerry can and use the pump to drain the tank? I don't have time to drive around just to waste fuel. Or is there another way? Go to top Share this post Link to post Share on other sites
Report post #2 Posted 12/08/19 12:23 PM you can just bridge the relay for the fuel pump and pump straight out of a hose into your jerry can. 1 Go to top Share this post Link to post Share on other sites
Report post #3 Posted 12/08/19 12:27 PM You would have to hot wire the pump as when you key on the pump will prime then stop. You could probably disconnect the return line under the car and feed that into a jerry can with the engine running? Edit: whoops Keith and I must have been typing at the same time!

Report post #6 Posted 13/08/19 08:35 AM Unless I read the OP incorrectly, doesn’t he just want to replace the pump?You can do that with any amount of fuel in the tank. Go to top Share this post Link to post Share on other sites
Report post #7 Posted 13/08/19 08:49 AM that's not a good idea! When you undo the fuel module the tank will empty to just under half with fuel going everywhere, bloody dangerous! Go to top Share this post Link to post Share on other sites
Report post #8 Posted 13/08/19 08:55 AM I swapped out my fuel module in my FG F6 with well over 3/4 of a tank and nothing happened. Go to top Share this post Link to post Share on other sites
Report post #9 Posted 13/08/19 10:28 AM I thought the tank had to be below 1/4 before you could open the tank with out fuel escaping on a sedan? Go to top Share this post Link to post Share on other sites
Report post #10 Posted 13/08/19 10:32 AM I’m not sure why, it’s a tank and the module comes out through an opening in the top. As you can see from my picture my tank was close to full and nothing happened. Disconnected the lines and pulled it out, fitted new module and reconnected the lines and no issues.

Report post #12 Posted 13/08/19 11:56 AM That may be so but I encountered no issues changing out my module with a full tank. I’m still struggling to understand why it would be an issue. Go to top Share this post Link to post Share on other sites

Report post #14 Posted 13/08/19 11:59 AM This shows where the pump fits, in the lower part of the tank. Would 1/4 be low enough to take out the pump? Go to top Share this post Link to post Share on other sites

Report post #16 Posted 13/08/19 12:04 PM To change must be less than half on gauge. 1/4 is better. 1 Go to top Share this post Link to post Share on other sites
Report post #17 Posted 13/08/19 12:13 PM Yeah maybe I was lucky, I never read anywhere where it said to have 1/2 tank or less so I just parked it up and changed it out. When I could see the fuel level just below the opening I assumed it was close to full so it appears I was closer to 1/4 than full based on the shape of the tank.

Bellenderitous is correct for once anything past 2/3rds will piss fuel everywhere when undoing the retaining ring halfway is a great guide without issues Graeme if you’re not 100% certain I’ll happily do it for you Go to top Share this post Link to post Share on other sites
Report post #20 Posted 14/08/19 12:33 PM Thanks for the offer Aaron, I think I will be ok doing it, I just was not sure how low the fuel had to be. If I have any trouble, I will give you a call. I appreciate all your advice and help buying the parts. I started working on the car today, I want to do all the work that has to be done on the ramps first, because I won' be able to drive it up the ramps latter, till its tuned. I'm thinking of doing the pump while I have it on the ramps, to keep the fuel at the back. 1 Go to top Share this post Link to post Share on other sites
Report post #21 Posted 19/08/19 09:24 AM Thought I would post how I got on. I ended up removing the fuel filter under the passenger side of the car. I cut about 4 metres of a old garden hose and slid it over the pipe and twitched it on with wire, I put a plastic bowl under that to catch anything that blew past and the other end in a Jerry can that I could see from the front of the car. Then I followed K31th's advice and bridged the the fuel pump relay. I could hear the fuel pump start. It took about 5 minutes to pump out 20 litres. 1 Go to top Share this post Link to post Share on other sites
