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...

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...

Is the fuel pump working properly ? Also is the tank & fuel clean. Doesn't take much debris to block the float valve. SU carbs are so simple you should be able to strip, clean & rebuild them yourself. Had many non LR cars with them years...

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.

There is a link pipe between the carbs(feed)used to be black pipe with 2 t pieces,on the rear of the carbs This then returns to the tank & has a smaller hole to make a restriction. If no restriction fuel flows freely past the carbs & wont fill...

Have you replaced the strombugs with SU or did you buy it like that? Do you have a problem?

Have you got the small fuel pots before the carbs? These are like swirl pots. Also make sure you have a restricted return so the fuel does not bypass the carbs. What fuel pump are you using? & where is it If the fan is still on the engine air...

You sure it’s not electrical? Coil getting too hot can cause this as well

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...

Have a look and see if the valves (if fitted) on the butterflies are ok and not loose or something, Its a little plunger thing with a spring, anti run on or something. Anyway, one of mine got dislodged and the engine ate it, revs went up as it...

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...

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
