rear petrol tank

Alfhare · Sep 7, 2018

my 110 89 pick up has a rear tank and the sender is faulty not wanting to remove the sender yet, but just wondering if there is any difference in a petrol tank to a diesel tank and also the senders for petrol and diesel????
The reason for asking is that it did have a 3.5 ltr petrol engine and is now fitted with a 300 TDi also diesel is leaking slightly from fuel cap when full, is this because the cap is for petrol???

cheers

I'm fairly certain they are the same , think the fuel return pipe is blanked off on the petrol with a removable fitting.

so i should buy a petrol sender???
i have 3 wires going into the sender i take it this may have low warning light or is this standard for non and with warning light.

Buy a TDi sender??? there is no return coming from sender as the return is fitted on the tank somewhere, most desiel senders ive looked at have a return fitted to them.

so whats the pipe thats sticking out of the sender on deisels but not on petrol am i missing something here as the one thats fitted at the moment has no tube going into it only 3 wires as i think this is the original tank when the v8 was fitted.

a diesel sender has a pipe connector for feed to lift pump on the inside its a stack pipe that draws from the bottom of the tank

i see but my lift pump is connected to a a glass bottom thing attached to bulkhead under the bonnet, so if i bought desiel sender would i have to bypass this and fit direct to lift pump or just buy a sender without a stack pipe????
i think ill have another look and take pictures on what ive got that might help to explain things.
at the moment im making a list of things that need attention and see if i can buy at the LR peterbourgh show next weekend, my list is getting bigger by the day.......doh

? why theres only one feed from tank and with a 300 tdi its from sender unit to the front ie lift pump

Alfhare · Sep 8, 2018

so Ive attached photos the lift pump is feed from the bottle looking thing, also there is a pipe that goes to carb and a hose from tank. as you can see there is a pipe that has been bent over and cable tied so to prevent anthing coming out i assume. if any one can enlighten me on any of this please, as it all started to find out about my fuel sender.

normally theres a direct feed from tank to lift pump from there to filter from there to front of injection pump, and if using red a glass bottom filter isnt recommended, that filter head is for a 2.5 na or td so has a return from injector rail tdi return goes to rear of pump then straight back to the tank,youd be better with the correct tdi filter head and pipe work
