I'm about to fit a Walbro GSS-341 fuel pump to my ute.

One issue I've had so far is finding submersble fuel line...

I've found that Gates make it and the part number is 27093 if anyone else is chasing some.

Trade price is around $30 per foot, and any Repco can order it for you.

Hey Adam. You talking about those semi transparent concertina type lines between the pump and the pot? If so, dont they have ends that are longer than the concertina segments and therefore makes buying a foot length useless?

Nah, the stuff I was talking about is made from black fluoroelastomer with aramid fiber reinforcing. Looks like ordinary fuel hose but it's submersible.

Are you saying the stock hoses are longer than required and you can just cut and clamp them to the new pump?

Nope. Unfortunately you cant slip off the one tube that's attached to the pump outlet. You cant even cut as it then wont be long enough. Not to mention that it needs a longer end that isnt concertina. I thought you get a piece of submersible hose with the pump. I did.

Nope.

I just ordered a foot of the stuff, I'll pick it up tomorrow...

Now for the fun job of getting the pump out of the ute. :spoton:

Ah yes. Utes. It'll be easier to sell it and buy a sedan so you can then have issues with CVs :spoton:

Here's a link if anyone needs some...

The Gates Submersible Fuel Line Hose :spoton:

I don't think it will be all the difficult.

I'm going to take the tub off to do it...

Remove liner, disconnect tail-light loom, unbolt tub (8 bolts) and lift it off.

Sounds easy, I guess I'll find out. I'll take a few pics of the job. :spoton:

Adam, you can't access the tank that way. There is a rail, ( Steel ) which runs directly over the tank. Have a look from underneath before you take the time to attempt it :)

Go in over the back of the diff ( on a hoist ) and take all bolts out, and the bracket from the top. The tank will 'slide' around, and will drop enough to get the pump attachment out. It's a twisty excersize, but I've done it three times now, and from getting it on the hoist, getting the pump out, modding it and putting it back in took me 50mins.

On the fuel hose, no real need for the submersible line, just soak the factory line in boiling/hot water, and slip it off, drop it back on with a clamp, done. :)

I'm still running a modified factory pump, but will be fitting surge and external soon. I can't bear to get under it again and try and get the pump out..

Today I fitted my Walbro fuel pump.

Ben, I had a go at it your way but without access to a hoist this weekend I just didn't have the room, so off with the tub.

Removing the tub can be easily done in about 1-1.5 hour.

First thing to do is remove the tub liner, all screws and bolts are obvious to see so it's very straight forward, there's no reason to remove the tailgate section of the liner. Once you've done that you can lift the liner out, you may find that you have to pry up the base of the liner as some are stuck down with a bit of double sided tape.

You will see 8 bolts (4 down each side), these hold the tub down to the chassis, undo all of these.

Disconnect and remove all of your taillight globe and number plate globe connections. Now feed the loom down out of the chassis so it doesn't get caught when you lift the tub.

There are 2 scrivets that need to be removed from the chassis that help hold the the rear wheel arches in place. If you look at the chassis rail from the back of the rear tyres you will see them.

If you have a towbar fitted you will also need to remove that aswell.

Now you are ready to lift the tub off...

I had 2 other people to help me lift the tub off and it was easy enough to do, but obviously the more people you have the easier it will be.

Now that the tub is off you will see this...

Note: It's a good idea to wash underneath and especially around the fuel tank and alot of dirt collects on top of the tank and you don't want that getting into the fuel tank.

The fuel lines are a push and squeeze type connection and they come off easy enough. Once the lines are off remove the screws holding the pump and cradle to the tank. Be careful not to knock the seal into the tank (Marcus :spoton:).

Lift the cradle out and remove the lower half. To do this you need to pry the 2 lock tabs away and pull down on the lower section while holding the hose and fitting which isn't connected to the pump to the side so it can slide past the housing, you'll see what I mean when you get it apart.

From here it's straight forward, remove the pump, measure and cut the hose, cut and join the pump wiring loom to the new loom, this has to be done due to the Walbro having a different electrical fitting. Now just reassemble everything.

If I didn't have a crack at doing it Ben's way first I think I could of done the whole job in about 3-4 hours. As I said if I had access to a hoist I would of done it the way Ben suggested, but on this occasion I didn't, but it wasn't that bad a job anyway. :laughing:
