[diesel_mercedes] Re : Now air bubbles coming from tank!

 


Don't panic ;

It's just an air intake leak , very common .

Either you have the wrong size rubber hoses between the steel pipes and the injection pump or , you have normal incorrect ideal gear / screw typ hose clamps, neither are any good on Metric vehicles , now you see why .

Loosen the clamp and try to twist the hose ~ it should be difficult , if it's easy to twist on the steel fuel pipe or the plastic clear screen , it's the wrong size hose , you need Diesel Rated 7MM hose , not 5/16" crap .

Once in a while , the DPO (remember the kid you got it from?) screws 'round with the hose on the bottom of the fuel tank to the frame's steel fuel pipe , replace it as necessary & replace the gear/screw typ clamps with the proper band typ of clamps you cleverly grabbed @ Pick-A-Part.....

If the hand primer pump has a white(ish) plastic knob you need to turn to unlock the pump before using it , it's prolly worn out , replace the hand primer pump , the newer style ones have a much smaller black push knob you don't need to lock and unlock , I prefer the older white knob ones as they work much better and still show up in some partshaus' .

You're getting there , imagine you're resurrecting a 1931 Fordson Tractor that some Farmer abused for 50 years , it takes a fair bit to undo all the screwy & wrong things the DPO did before you have a nice old reliable , economical Mercedes Diesel on your hands .keep at it .

Nothing worth having , is easily gained .
