If I fit an electronic fuel pump to air cooled 650 unit and thus fit a blanking plate where the mechanical pump used to be,should it have a breather tube or can it literally be a plate with no hole? :-
-
The fuel pump is a what it says and not a combined engine breather . I know that some suppliers of tuning parts sell a plate with some sort of breather. On the aircooled crankcase pressure is relieved by the spring valve on the oil filler cap back to the air filter of an oil catch tank if you are running a fancy set up. I ran an electric pump on a nearly new Bis for a couple of years with no problem :)
-
I thought that would be the case , only because the bakelite block is bust,20mm thick but some are thinner probably for the 500 engine. Perhaps I could use the thinner block with a shorter rod but NOT cut down the longer rod of the 650 as I guess it hard faced ,a bit like sope shop assistances!!
-
Does the rod need to be in place if you have removed the fuel pump ?
-
this is confusing if you have removed the fuel pump for an electric pump then you no longer need the push rod as this only works the mechanical fuel pump by being pushed by a cam. you can block the hole that the old fuel pump has left by making a plate and gasket and do not need a breather if you wish i suppose you can buy one of those gucci breathers but as to what use it really is is way beyond me! perhaps smallcox can help and explain as i am sure he has one on his engine or knows what the pros and cons are?
-
Removed mine, dumped the rod (bent it getting it out). then made a plate and covered the hole. Works fine (so far).
-
Leaving the rod in would be crazy as the blanking plate would`nt fit anyway, so I think I will fit a leky one.

If you fit an electric fuel ,pump do you need to fit an automatic cut off swich in case you are involved in an accident. How and what do you need to do this.

Use a fuelpump relay that have coil input.. so when the engine stops, the fuel pump stops..

Some variants of it :)
The extra breathe will make the engine happier :) Better oil, and no oil in the rocker room in high rev. ;)

I wonder if this would be any good?
