[Tigers] Parts Info Request...

[Larry Mayfield]

Ok, I am into repairing my gasoline smell in the car. My car Vin’s last 4
digits are  1136 so it is not the newest nor oldest car in the garage.  And
I have owned this car since 1967, as second owner.  Way back when, just
after I was married,  the SU AUF 301 fuel pump died.  I remember the new
wife and I happily driving up high way 101 and having to rap the fuel pump
occasionally with a tiny ball peen hammer to keep it functioning.   I did no
replace it with a new AUF 301. Instead I installed one of the American made
pumps that pulse almost continuously.  But, I digress a bit. I started the
smell repair operation by removing the trunk panels that hide the tanks and
the cross over pipe. I have purchased the hose connectors, 4 each, for the
cross over and have a new filler neck hose, fuel sender gasket, and Tygon
vent hose connecting the 2 tanks ventilation together.  Fuel and lube
compatible Tygon is spendy, lol, about $2.50 per foot. But should outlast
the car, lol. Sold on ebay occasionally.  My next operation was to open the
fuel pump access door, disconnect the fuel pump feed line and drain the
remaining fuel from the tanks. I even moved the car to the shop concrete pad
to make sure that  if some odd even happened and the whole mess caught on
fire for some reason, it would not burn the shop down, lol. I even removed
the battery to assure the car was electrically dead, i.e. no sparks.  I
looked upon my install of nearly 42 or so years ago and I noticed something;
I had put a piece of a split heater hose around the  connections to keep
stuff from rattling, and when I touched that, my finger became wet with,
wait, fuel! So it appears that I have serendipitously found the source of
the smell.  I did the touch test and  mirror looks and found no other weepy
leaks anywhere.  When the stuff I had installed to prevent noise was
removed, the leak was coming from the tank to pump feed line fitting where I
had adapted the British ferrule to American fitting. Only there and not the
outlet side, go figure. Dry on that end.  So, if I am any judge of my past
repair work, I am guessing that there is a mismatch between the Brit side
and ‘mercan side. 

 

And while I am interested in maintaining as much OEM stuff as possible, I am
not interested in obtaining a new version of the SU fuel pump. What I need
is a source for a fitting that will use the Brit fitting on one end and
American fitting , ie ¼ inch pipe, on the other.  I know there must be at
least among us who has done something similar and knows where I might find
such a beast. I need two of them.  Brit pipe fittings, as we have seen from
the temp sensor, have straight threads and a fiber washer to seal fluids, at
least in that era of car manufacturing.  In the process of repairing this to
be modern and safe, I am also adding a canister fuel filter, a Summit Racing
one which has ¼ inch pipe threads before the pump to save the pump from any
possible debris damage, although the fuel I drained looks clear and useful.
And I will also add a larger inline filter before the carb to keep crap out
of it as well, should such be in the line.  

 

I am also contemplating changing all the fuel line connector hoses; those
short pieces that are along the line I guess to aid in assembling the total
fuel system.  That’s pretty straight forward. Except, how many of those are
there?  I see that Earl’s has a new hose that  does not let vapors though
and while spendy, a foot of it to cut into short pieces won’t break the
bank. 

 

 

So, to summarize, I need help on  three pieces  of information:

1.   Where to get fittings that will adapt the British side of the fuel pump
install to American pipe threads, just a source or suggested places to look,

2.   how many of the short fuel line connector hoses in the under car fuel
line run are there are so I know how much to order from Earl’s (A Holley
Company now). 

3.   On the cross over pipe between tanks, is the outlet pipe to fuel pump ¼
inch pipe and if so, is it a straight thread Brit, or tapered American pipe
thread.

 

And a final comment relating to the cars design.  Who in their right minds
would run fuel and brake lines inside the tunnel next to potentially
whipping drive shaft pieces in event of front u-joint failure! Totally
insane. 

 

If any can help on 1,2,3 above I would appreciate it!
