Yes, it’s a v8 from a r.r. Classic 1983. Original series 3 petrol tank. Can I keep this pump and work out a way to return the overflow back to the tank?

Ah yes I see. I did have a look on the link pipe a couple days ago but I'll look again. Thanks very much to you and all. P.

OK thanks. So if I squash the overflow pipes and the pump stops priming it would suggest that the pump is too powerful for the su's. I might see if these overflow pipes are actually meant to return to the tank somewhere/somehow. Tomorrow is another day!

I have a feeling the red top pump might be one that provides too much pressure. Do they have adjustable regulators on them?

If it was just one them I could understand that but as it's both it does seem a bit too much of a coincidence that both floats aren't working properly no? Although possible I guess.

It's a redtop fuel pump (just checked) and the overflow pipes don't actually go to the tank on mine. They just dangle out the bottom of the engine bay.

Evening all My electric fuel pump won’t stop making the priming noise when I turn on the ignition and causes the the twin SU’s to both drip fuel out of the overflow pipes and onto the ground. It continues when the engine runs too. It’s a 3.5 V8 fitted in my series 3. The fuel pump is a retro...

Ta, would like to know if anyone has done this with a v8 and found the gain adequate. Just don’t want to change it twice. P.

But it needs an upgraded radiator as the old one for the 4 cylinder engine isn’t coping at all well. Anyone got a series Landy on here with a rover v8 in it that has a radiator that copes ok? Any recommendations? Ive seen an aftermarket upgrade radiator specific for series landys with v8...

I agree. Just not sure what else it can be. Steady drip/pour as opposed to gushing but yes. Might buy a replacement manifold. Dont know whether to try it first. Such a bummer!

It does look dodgy. But I’m hoping it’s not it. We didn’t need to pressurise the system as water was coming down the back of the valley without it being under pressure. We just couldn’t see from where so we had to just take the manifold off. Which makes me think we would have seen it coming from...

Yes. Wondering about the way it joins the casing. Could be yhe culprit. Wondering what I could do to seal the gap? Does anyone know where the "o rings" are? Apparently I should change them too.

Cheers. I'm well on the way now. Lots of bits ordered. Just getting the top layer of limescale deposits off.

That is amazing. I'll have a good read. Thank you so much.

I’m now wondering if it could be the steel (?) pipe that is attached to the underneath of the manifold that runs the whole length of it front to back. It seems a fair old a steady flow of water from the valley to be just a gasket leak. It did look rusty when I lifted up and half removed the...

Yes. I'm thinking that's the one cheers. I'm off to buy some bits! Thinking of using my multi tool with the light sand paper fitting to clean the manifold surfaces. Good or bad idea?

Hello good people. Shall I buy the tin valley gasket or the composite one. I’m leaning towards the latter and it doesn’t require sealant. Thanks a lot, Pall.

Thank you. !

That is brilliant thanks so much. I did wonder wot people were on about when they mention the seals. I tookk the two metal plates off and didn't even notice the seals. They could well be the culprit. ! Where do suggest I get these bits from? Gasket too.
