TR4/4A AC Fuel Pump stuff


Freshman Member
Hello to all you brave classic AND vintage (ya-I believe theres a difference LOL) British sports car owners!!

I am the proud caretaker of a 1963 TR4 and a 1972 Alfa GTV 2000

Definitely have learned the value of reaching out to owners of the make(s) for helpful tips on how to keep these "old girls" running! It's a fun moment when you pull up next to a modern car and get a thumbs up from the driver - not to mention the attention when parking and exiting to go get a snack!

Anyhow, currently in the midst of re-plumping the Triumph and got stumped by a freshly rebuilt "leaky fuel pump" (compression fittings) after ALL my trouble to rebuild, reform and restore some cleanliness to the fuel delivery. knuckles not too skinned, but head scratching was plentiful.

Glad I found BCF! Came across the bit by Scott Suhring on modifying two "standard" brass ferrels and will give that a try. I gotta fix this leaky connection!!!!! Had been driving it with the existing pump and lines wet/leaky and decided I better figure out how to fix that - lol ...I don't want to be literally be "cooking with gas".... :smile:.I'm onboard and agree with the fitment issue of the brass ferrels available being too short, so I'm trying Scott's suggestion - unless you fine gents and ladies can point me to a source for "original fit" olives....look forward to learning all about owning and driving this cool little car!!
Cheers, Armando

"White flag waving"!!.... okay, does anyone have a different suggestion which has worked for you when refitting new fuel lines with the "available" compression olives which we have to work with??
I failed miserably at cutting them in half to sandwich two together....

really stuck now...thanks all! let me hear whatcha think - Armando aka Adele's Caretaker

I have done the double olive successfully. Instead of cutting the olives, try sanding them down.

I just googled "elongated brass ferrules". It produces interesting results, indicating that the product is not foreign to current manufacturing. winzeler stamping.com; eaton.com.

I just reduced the number of threads in the pump...allowing the compression nut to go deeper into the pump and effectively compress the ferule ("olive") Fuel Pump Modification 001 (2).jpg

Reduced...I cut some threads off the pump.
These pictures show the reduction of about 2 threads.Fuel Pump modification 001 (3).jpgFuel Pump Modification 001 (2).jpg
