The V8 Owners Forum -

Hi I have a MGB with a 3.5 and a lt77 gearbox. The rubber bushes perished after 20 years. I’ve managed to change them with the box in situ (with great difficulty) any way all back together but I can’t select gears the gear lever will only go front to back. I’ve looked around the net but can’t find h...

Thanks for the reply minorv8 Yep that’s the one, I’ve been looking at shaving the manifold could be possible shortening the SU would be easier I’m going to shorten the Dashpot and use a flat top damper and see how it works. If it doesn’t run well it’s not to painful to return to normal. Thanks again

Thanks for the reply minorv8. I have ordered 2 of them which would probably be fine but the Dashpot comes up through the hole hence the deeper damper top. I guess I will have to machine the Dashpot top to get full travel is that okay to do?

Hi all Hopefully you can help I have an MGB V8 which I want to fit SU on an aftermarket copy of the trouser manifold unfortunately the carbs are about 10mm to high. When looking at the internet noticed a firm selling shortened SUs. I could do this my self if I knew the procedure. Anyone know what’s ...

Hmm we used the relays off the old Flapper system they worked fine what is the diode for?

Thanks agai for the reply yes the relay is in place when testing I have power at pin 15 haven't checked pin 2 where does pin 2 get its supply from?

Mick

Thanks for the reply Dave I thought that is how the pump worked unfortunately mine isn't doing that. The live comes from the ignition switch to pin 86 and pin 19 on the ECU. The earth which comes from the ECU pin 16. The relay is the one that came with the engine and loom purchased as a working set....

Sorry Ian don't understand your last statement, the problem I have is the fuel pump relay is not pulling in there is power to the relay but the signal from the ECU to Earth the other side of the relay is not present.

Hi all we have just installed a Hotwire EFI 3.9 into a Range Rover that had flapper we have replaced the harnes. We've checked there is a live supply and a switched live supply and the 2 earths go to the battery neg. the gearbox inhibit switch is working and putting an earth to the ecu. The problem ...

Hi all I know this has probably been done to death and I did do a quick search. My recently overhauled 4.2 v8 has a noisey lifter after being left for a day or so on start up it goes away afetr a couple of mins. I have the inlet manifold off and checked the lifters and they all look great. I checked...
