mine's tiny!

mines tiny!

as part of my ongoing fuel line refurb i've discovered that on purchase of a 2nd hand pump and accumulator that my current accumulator is the same shape as the replacement but approximately 1/3-1/4 smaller. the bracket looks like it fits the replacement and looks too big for the accumulator on it now.

i am confused. if it's the wrong one how come it appears to work? which one is correct? would having a 'small one' account for minor running problems i've had in the past? if it is the wrong one where's/what's it come from.

mind you since we bought this car about 4 or 5 years ago we have replaced some 'aftermarket' spares, such as an assortment household plumbing o washers for real injector seals- so nothing would surprise me!

also any tips on fitting/testing/cleaning second hand fuel pumps/accumulators would be appreciated.

cheers

bit of a hit and miss i guess. you can't run the pump to test it dry as the fuel lubricates the pump and would probally kill it. if you connected a hose to the inlet and outlet and let clean fuel run tro it to remove dirt e.t.c. but caution is advised as the pump runs to 8 - 10 bar, and as for the accumlator i'd imagine a to small unit may cause problems because if a smaller unit was good enought, then vw would have used the smaller unit….may come from a 1.6?? don't really know

Read recently that "old style" accumulators are smaller and more rubbish.

Not sure when they changed.
