I'm in the process of pulling out the 70 litre long range custom tank in my GQ RB30 Patrol.
Tank was installed quite a long time ago by the looks of it. (twenty years or more I reckon).
I'm pulling it out to diagnose a possible loose power connection to the petrol pump or possible intermittent pump issue.
I discovered it is a real PITA job to remove this custom long range tank as it's a tight fit.
I'm wondering,
1)Does it make sense to make a new pump access point from the floor above for future accesss ?
By the looks of it, the petrol pump is just under the right hand side rear seat.
So, I'll be looking at removing the rear seat, carpet and cutting a hole on the floor and make the proper removable plate to cover the hole.
Is it worth it or is it an overkill?
2)Is the petrol pump the same as the original factory one? Do they simply use the factory petrol pump with the custom made Long rank tank? Do I need to pull the petrol pump out of the tank to find that out?
3)Are there any external pumps from other vehicles that i can adapt for this RB30 Patrol?
Long Range Automotive(LRA) were the people who installed the tank.
with making a new hole in the floor -
are you expecting to take the tank / pump out again or not for another 20 years...........?
have a think
easier access, yes
but
the time to cut a hole, in the right place - correctly
making a cover for it
making it sealed (for fumes and dust and water)
is it really worth all that work................................
with the petrol pump.............
as the GQ's never came factory with an Aux fuel tank, so there wont be an original pump in there
unless
they have taken one from a main tank
or it could be any type of fuel pump - you will have to pull it out to find out what type it is
I would be hoping they used the one out of the original main tank myself............

It's pretty damn hard to pull the tank out. Front bolts took ages to get them out.
Everything's out, but I still can't pull it out in that tight fit.
There has to be a certain way that I need to tilt it to get it out.
If I put a brand new pump I won't have to worry about cutting access holes on the floor.
But, I won't be putting in a brand new pump. It's way too expensive.
If the pump is faulty, I have to see whether it's fixable.
If not, I need to get a used replacement or rather I prefer
an external pump, assuming there's such thing to suit the RB30 carby patrol.
if it was me.... i 'd put a new pump in, make sure tank is clean inside, check the wiring and replace if needed. put tank back. ignore for another 10 years. cutting holes is a pain,
Need to get that big fuel filler hose right out of the way, then lower the rear end of the tank first, then slide backwards under the diff. It's a real PITA.
Looking at your pictures, it looks like it's the plumbing at the rear of the tank that's stopping the tank from coming out or is the rear of the tank sitting hard up against the diff?
The wire harness in your pictures from the fuel pump will more then likely run down to the rear of the vehicle and connect to the original fuel pump wiring harness (where the original fuel tank was) have you checked these connections?
My guess is they used the original fuel pump and sender unit from your original fuel tank. You should be able to pick up an aftermarket fuel pump as a direct replacement.

Thanx mate. It's a pretty tight fit. Tank is only few millimeters from touching the drive shaft. Driveshaft had to come out. Yeah, the wires connect the wire harness at the back of the vehicle under the LPG tank. I did check, but it's pretty hard to make sure whether the connections are dodgy, 'cos they appear to be permanently crimped connectors. 'Cos the problem is intermittent, I thought it's best to rewire the connections from the pump to the front of the vehicle with new wires and a conduit.
An aftermarket fuel pump should be ok I reckon. I checked fleabay yesterday, but couldn't find a one.
I'll try the local spare part shops today.
I like the idea of having an access hole, so I can carry a used pump in case it needs replacement in future. But, cutting a hole is easily said than done.

Yeah, that's true. Cutting a hole is not easy considering the spot. I prefer an external pump, but it doesn't appear to be a solution without some fiddling.
I have the same tank in the same spot and when the car flexes, the tail shaft slightly touches the tank. Only started doing it on the last trip because the tank must have taken a hit, it has bowed out on the side a bit.
I will have to drop the tail shaft and bash the tank in.
