To give our fuel pump some vibration damping, we cut out a sheet of a very expensive sheet of chemical-resilient Viton to wrap around our fuel pumpWith the Viton now cushioning the fuel pump from the hanger and the hose clamps holding the pump against the hanger, we were very happy with the end result. This has to be one of the cleanest Fuel pump installations ever made for an NSX that is capable of ~600whp on E85 and ~800whp on gas.
Stay tuned for future installment of Project NSX where we tackle the rest of the fuel system!
Thank you. Contact Brown & Miller Racing Solutions and tell them the dimensions of the shaft and barb of your fuel pump fitting (I can’t remember off-hand) and they will get you the correct part number. The wire bulkhead connector is ATL CFD-504.
Only issue is wire configuration: fuel vapour will travel up through the wire – wire can never be installed like this; a better solution is to connect each end independently to studs.

This looks so clean! Can I get a parts number list for the fittings/lines/bulkhead connectors please? Thanks!

Great solution.

Those bulkhead wiring connectors have been used in professional motorsports for decades without issue.
This sort of bulkhead wiring has been done by OEM’s and in Professional motorsports for generations.
What made you decide to keep the factory return hard line? With all the work already done, did you consider making the return line bigger?
