Gas Tank fuel pickup

[cmoanz]

After having some fuel starvation issues with my 70 911T (Zeniths), I decided it was time to drain the tank. I was expecting to find a clogged fuel pickup filter like this:



Instead I found a very clogged and rusty banjo bolt setup:



So I proceeded to pull out, grind down and refinish the outside of the tank with POR-15 and 3M rubberized undercoating, clean up the banjo bolt and the tank interior:



My question is should I replace the banjo bolt setup with the screened pick up like above? I know that people have issues with the screen after sometime, but it appears to me the banjo bolt could quickly become fully blocked.

Your ’70 911T should have a front cross member mounted Bosch electric fuel pump. Is that the case?

Normally that pump used the screen inlet filter fitted to the left (driver’s side) large port in the fuel tank. The pressure relief return from the pump goes back to the fuel tank via the banjo fitting at the drain plug.

Your picture seems to show the two large ports closed off with original-type screw plugs and the fuel pick-up at the drain plug banjo bolt. The fuel pick-up should be through the screen filter (your 1st picture) in the large port. Un-screened pick-up at the drain plug is not a good idea.

Be sure and use the brass screen filter OE 911 part and not the OE 914 plastic part. Note that there are two versions of the 911 screen filter fitting; one with a 6 mm OD nipple (901.201.023.01) to fit 7 mm ID fuel hose and one with an 8 mm nipple (901.201.023.02) to fit 9 mm hose. The 9 mm hose is used for the inlet of the Bosch electric fuel pump, 7 mm for everything else.

Be sure and use the original Norma-Schellen hose clamps (size 12 for 7 mm hose).

As usual, use extreme caution with fuel. Gasoline is the most dangerous substance you normally ever come in contact with – unless you build nuclear weapons. The 911 you save will be your own.

Best,

Grady, thanks for the great replies as always! the my car current has installed a Bosch 0580 960009 (which I assume from the newer hoses was a replacement)



Based on your post I relooked at how it was configured... it appears that the PO t-ed the return line back into the line from the tank. Capped off the screened pickup and moved the pick to the return banjo. Additionally all the fuel lines have been replaced (in the front with 5/16" lines).

So assuming I'm good with what appears to be a 914/6 pump. I will buy a 901.201.023.02 pickup and new 9 mm hose then reconfigure to the correct pickup a return.

Thanks again Pelican is the best ever!
