Fuel Pump + Sender Gaskets

Every since the electric fuel pump and new sender went in, the nitrile rubber gaskets that were supplied as standard would weep fuel....




Interestingly, Tanks Inc. now offer a cork option...

Time to swap the nitrile with cork...

The one on the right!

With the carb rebuilt and back together, it was time to wack it back on and fire it up!

Time to pick a gasket (two came in the rebuild kit)...



The one on the right matched what was on the car to begin with, but I wanted to try the one on the left as it seemed to match the pattern under the 4GC.

Ahhh... no. With the carby sandwiching the gasket on the left, the old girl would fire, but quickly die and would only sputter along if I held plenty of revs... all the while hearing a MASSIVE vacuum leak.

Left it all for church, then after church dug into swapping the gasket for the one on the right.

With the right gasket in place... muuuuch better! Idled fine, revved fine; all good.

Exhausting!

Based on Joe's findings from his disassembly work on Thu 20/10, I went shopping...



I grabbed 2 x exhaust flange gaskets ("donuts") and a heat riser flange gasket. Plus I took to opportunity to acquire another generic exhaust hanger to finalise the hanging of the exhaust in a neat and tidy fashion.


The heat riser gasket mount holes were ever so slightly different to what the Chev had, so a quick massage with a hole cutter and voila!...



A perfect fit.


Finally, Joe made a mod to the heat riser valve...




He cut off the shaft and extracted the butterfly, then drilled out the hole for the shaft and inserted a bolt/nut assembly to blank it off (see photo above).

This shot shows the complete bolt. The final install had the bold head ground down and exhaust cement to help seal.

Till next time,

John out.
