Mystery Lower Radiator Hose

[Son of Marty]

I'm sorry but there's nothing that will pass through the fuel line that will damage a diaphragm pump in anyway. The pump on a m10 will pass a bb and never miss a beat, but having a air pocket due to the filter never being  fully of fuel will reduce the pump suction quite a bit, let alone as the filter clogs, put the filter on the pressure side of the pump before the carb.

Diaphragm Pumps can transfer liquids with low, medium or high viscosities and also liquids with a large solids content.

Hien, good eye.

The fuel filter...yep..I know.  The photo with the filter after the pump was taken 3 years ago when I purchased the car.  Fixed immediately.  See photo below from last week.

The filter before pump has no thoughtful basis.  Anything that passes thru the screen in the tank pickup will pass thru the pump easily.  Besides materials in the tank do not float and lay in the tank bottom.   A filter ahead of the pump increases the chance of vapor lock.

I understand the aforementioned logical points.  So, delete the filter and eliminate the real/potential air pocket.

BMW never fitted a filter on carb cars before or after the pump, many dealers decided one was needed cause most merican cars had them, although if you look at the pumps the filters were after the pump.

Hmmm...go figure.  Got it.  All makes sense.  Thanks.

I have a LRH rubbing against the frame and looking quite nasty.  LRHs for 2002s sand E21s don't look like they will fit b/c the radiator outlet is on the side. 

Q:  Any suggestions re:

• a hose which might have the correct bends, shun the frame, and fit the ticket?  Looks like it might need >4 bends.
• the BMW series (IF it's BMW) from which the radiator was obtained?  That info might help me find a suitable hose.

 

Thank you.

Fuel filter goes before fuel pump

This is what happened when stuff get through the fuel filter and into the carburetor. Now carry extra fuel filter and tool to replace the fuel filter and take the carb apart and clean on the side of the road.

Perhaps a better description would be  “This is what happens when you drive a car with a bad fuel tank. “

Beautiful car .

I'm all for using a filter, just in the correct spot, with todays gas your mechanical fuel pump needs all the help it can get specially in hot weather.

Dang, John, that just might be the ticket.  Looks like it has the right shape, turns, and length.  Guess I'll have to stick with my customized verrsion.  Thanks.
