Just a note for any members needing to change their pump and
a) Haven't done a search to find this precious info
&
b) Don't want to go the route of hacking up their P38 under the back seat.

Removal of the tank is an absolute doddle, the big plate underneath is is all that holds it up, 15 mins of a job, the bastard is the fuel pipes out of the top of the sender/pump assembly.

Best advice I can give is undo the fuel pipes about 1/2 way down the car, 1 is a join and the other goes to the fuel filter. All going well, you might be able to get these off without causing damage to the fuel pipes.

If you leave the pipes connected when you undo the tank, they will probably split on the sender assembly leading to needing new pipes and a sender assembly as the pipes that rot aren't serviceable/replaceable.

Another P38 gem I discovered at my cost today :doh:

thats why it is better to change the pump via the floor under the rear seat.
 
i need to change my pump at some point.

do you have to take the tank off, can i really change the pump from inside the car???
if so then how. never changed the in tank pump before so would be good to no for the futre.
 
There are instructions to guide you where to cut the floor so you can get to the top of the pump without taking out the tank. I looked under and though it looked easy enough to whizz the tank out so thats what I did, at my cost.

Upshot is there are parts available to fix it without having to be ingenious about it.

Mikey, in depth explaination here http://www.landyzone.co.uk/lz/f10/tank-fuel-pump-template-p38-109368.html if you don't want to drop the tank.
Just be extra careful undoing the pipes mate.
 
1 question tho. once all the hoses are disconnected, how does the pump come out.

from the pics in the other thread, it looks like it unscrews?????
 
The sender/pump assembly comes out as one and is held in by a mahooooosive plastic 'nut' which tightens down on top of the sender.
Once that is undone, it just lifts out.

Update on mine, new pump back in and it should run on petrol now fingers crossed (as soon as the engine is back together, just the aircon, PAS, Alternator, belt and plenum to refit lol).
 
lol , so its going well then mate :p

stupid p38, classics already have a hole in the boot floor to take the pump out- and I dont mean a rust hole lol :p
