Re-fuelling a 3500s - Why is it so difficult?

Ever since I have had the above, I have had problems with the fuel violently blowing back. I no longer go to those petrol stations where the attendant inserts the filler hose as I end up with a shower of petrol. I have given up going to these and saying "in it not at it". I consulted a Rover enthusiast in Ashhurst (NZ, that is) who advised that the filler nozzle should be inserted only about a couple of inches and the filler remain vertical at all times. It certainly works. As a result I only patronise those filling stations where you serve yourself and (hopefully) save a few cents a litre. Do others have similar problems?
 
Yes , but I don't know why. I accept mine has to be filled slowly
Maybe petrol pumps in 1973 didn't deliver so fast?
It depends how far in / what angle the nozzle is at so I imagine there is some splashback which fools the nozzle into thinking the tank is full
 
Hi there
Looking at a schematic of the fuel filler,pipes and tank,there is not much drop on the fuel filler pipe.It is almost horizontal.This causes air locks in the pipe and blowback.
I would suggest filling slowly and don't put the pipe into the filler neck too far.I would even say,hold it away so you can see the end of the pump nozzle .
Hope this helps

I seem to remember mine filling better with the nozzle the wrong way round, I think that allows the bend in the nozzle to go part way round the bend in the filler neck. Give it a try.
 
It's the same with the P5's. The P4's fill quicker as the tank & filler are mounted lower & the pipe is straighter. Maybe it's the price to pay for having the filler mounted on the rear deck.
Do XJ6's have the same quirk (& theres 2 on them)?

Not at all. XJ6's are very easy to fill up. The tank is a straight drop below the filler.

I agree with the webmaster, I always turn the nozzle thro' 180° i.e. trigger upwards and towards the car - Always worked for me but patience still needed!

I filled the tank up in mine this morning using the `reverse nozzle` method and it never caused any problem whatsoever!

Go figure ???
 
I only ever put petrol in my V8-S once before I took it to bits.
I used a measuring jug! :laugh:
 
Erik suffers with the fuel blowing back out the filler too! Very embarrassing when your dressed smart, off to the pub, and then turn up stinking of petrol!! :p I'll give the reverse nozzle thingy a try. At the moment Erik's favourite tipple seems to be Shell V power super unleaded, with Castrol Valve Master Plus. Fat Git!! :laugh: :laugh:
 
I had forgotten about this issue. I have been away defending the free world etc, and remember getting home from other trips only to get covered in petrol when filling up the blue beast.
I think it is down to the anti-siphon thingy (technical term) that lives in the filler neck. I tried removing it in another car, but lost most of a tank to some thieving git late one night.
I also use the upside down nozzle technique.

Cheers

Thank you all for your welcome advice. I refuelled the Rover yesterday and I found that if I kept the hose nozzle vertical and extended into the filler about one inch (25mm) and did not let the fuel flow too quickly, I had no problems.
 
I tried the upside down nozzle technique.........He burped all down his rear wing!! I'll go back to my usual way of holding the filler nozzle just in the top of the filler neck :;):
