Hi yes. Well remembered! They came back from Burlen and it's fixed a weird runnin g issue I had. They had these weird over run valves fitted which have now been ditched. Flats, needle valves, seals all replaced. Definitely coming from the overflows as I have a fuel return pipe going back to the...

It's a 3.5 v8 (out of an early range rover). Floats, float heights and needle valves all spot on. Will check all the pump stuff when I get home from work. Thanks vey much everyone.

Hello I was wondering what pressure reading my patten red top electric fuel pump should be providing, how I could measure it and whether it can be regulated. It’s pushing fuel out of the over flow pipes on my twin SU’s and I know it’s not the floats/float settings or needle valves. Any ideas...

Thank you for this. The pump is a red top pattern electric pump. It's mounted close to the fuel tank but can't remember exactly where. Ill check it. Carbs are spotless, no crap or gunge anywhere. Changed the coil already.

Cheers. They were ultrasonically cleaned and float Chambers and needle valves were spotless. But I'm hoping getting rid of the over run valve thingies will solve the issue. I might get an old one and plau about with it so I can demystify the dark art of these little bleeders!!

Yes will do. I'm hoping the restriction is in the t-pice ie big hole little hole. Oooh matron!

Hmmm that's interesting. Please see my photo. The return is wider diameter than the link pipe. Is this correct? Also it runs fine for 40 mins. The horizontal pipe is the link pipe and I'm holding the return.

My initial thoughts were electrical. Replaced the coil already. Sucking in air noise from the left carb made me switch my thinking to fuel.

No I don't think there are swirl pots. I have after market fans electric thermo switch operated and a new rad and thermostat. Running temperature is good. About 82°. There is a red top (pattern) fuel pump with a return pipe to the tank. Don't know if it has a restrictior on it though. How can I...

I bought it with SU'S. The engine is from a range rover classic from the 80's. Yes, it's an on going problem. I have sent the carbs away to Berlen Fuel systems to be looked at. It runs great for about 40mins then starts coughing , farting, spluttering and sucking in air. Eventually coming to a...

Hello Has anyone on here made/purchased/fitted heat shields to their su carbs on a 3.5 v8? Looking at the possibility of doing this but can't find much to go on out there. Cheers Paul

Just a quick thought. I while back I replaced the distributor cap on the (electronic ignition dizzy). I got it off a brand new spare electronic dizzy I had. I see that in suppliers such as paddock etc that they state orange coloured or black coloured. The dizzy cap I replaced was orange but the...

Yes. An easy job too. Just hope the spare that came with the wagon is compatible and working. Soon see I suppose.

Cheers. Twin su's and an electronic module in the dizzy. I've always been a points man myself but it was already installed. I have a spare coil. Will go again tomorrow. Thank you for your help. 😊 p.

Hello. Drove it out in light traffic for a bit. After 40 mins or so the judder from a stationary position started again and got progressively worse every time I pulled away. Then hissing air, backfiring eventually cutting out all together. So I let it all cool down again then limped it home...

Good point. Unfortunately I have the feeling you're right. I say Unfortunately as it's the biggest job of the possibilities !

Ah. Good point. They are on free wheel setting at the mo.

I did check them. the one near the front diff has a small amount of play. But not a lot.

Weird how it's temperature sensitive though.
