[TR] TR4 Fuel Line fittings at Fuel Pump

[wbeech at flash.net]

If you put an elect pump ahead of the orig pump, will fuel flow through an
inoperable original pump.  I would seem this would eliminate the need for
excessive plumbing.

My Spitfire is done this way...most of the time the Facet is turned off and
the mechanical pump does the work.  The Facet is mounted in the engine
compartment just ahead of the mechanical pump.

Hi Jeff & Brian!
 
Yes! It can be done because I've done it to my TR4A.
 
Iinstalled all new lines, rubber flex hoses, PI clamps, Heat sheild 3 shut
off valves with a 'T' fitting. one line runs the org. way, at the Bulkhead,
I put the 'T' in & ran the other line up & around the engine & air filters
to the carbs & a toggel switch.
 
The gas runs thru the E-pump & the org line thru the M-pump to the carbs
WITHOUT the E-pump running. Then IF I do have problems, I can flip the
switch to keep me going so I can pull off to turn off the running to the
M-pump & open the bulkhead line & have the toggle switch on to finish off
the ride to work on the problem later that night or when I can get a chance.
