Breaking ford 390 fuel pumps

Just had a nice 66 Tbird 390, 4bbl, auto tranny brought home on a truck, the fuel pump was spraying fuel out of a hole on the top side of the pump body. I took it to the "zone" It didn't match what their puter said it was. It matched up to a 72 ranchero 302 or 351 W, I put it on, the engin ran for a couple of minutes and quit, no fuel.. pulled the pump and the lever was broken... took it back and got the one that was suspose to fit with the big filter on the bottom, it wouldn't clear the transmission lines,lower radiator hose and barely cleared the sway bar. Took it back got another ranchero pump thinking the first was defective, it lasted about 5 minutes before it broke... any suggestions on what I need to do besides bend the sway bar and cooling lines and find a different radiator hose? This is a very clean original car with 75k on the clock. The previous owner had the engine, tranny, suspension, paint & body done by fairly reputable places 1100 miles ago, but the car has been stored for the past 6 years. I'm not that familiar with Fords, so any help would be greatly appreciated!

Fuel pump

I use this one on my 68 cougar with a 390
enginehttp://www.jegs.com/i/Carter/180/M6905/10002/-1
pretty low profile, and pumps a lot of fuel

I've never used this one, but it is cheaper and probably looks more period correct.

Not telling you where to go, but jegs has free shipping and good prices. They have never done me wrong.

Hope this helps

The carter looks like the one the puter calls for. No way to get it in, anti sway bar, tranny cooling lines, and lower radiator hose are all in the way... The filter sticks down way too far... The after market ones may fit but it's pretty tight and those are kinda fat. Still don't understand why they keep breaking the pump lever?

the ranch for 66 had a 289 no 351 but a 352
the 65 t bird had 6.4ltr(390) or a 427 7ltr
the 66 t bird had a 390 or a 428
now the 390 and 428 take the same pump
the 352 and 427 take a different one.. (not listed at rock auto, but the pump mounting gasket and pump bowl gasket is)
ARE YOU SURE THATS A 390.. and not a 427 an early 66 model might have got a left over 65 t bird 427.. stranger things have happened

Well, the invoices from the shop that overhauled the engine has it as a 390. Are the pump levers for a 302 and 390 that different that they would snap off? I don't know why the first leaking one was working but the others break?

no idea, never looked at a lever side by side..
you sure you didn't mount the pumps that broke the levers upside down?

if it's a 427 a pump for a 302 or a 390/428 would not work right..


427 pump


390/428 pump



look at the arms.. not even close to the same..


holley and edel. make a 390 pump that's the size of the 427 one.. that will clear your parts the canester stocker won't.. but they are 130.00
I'd find out what is in that car..

holley 390 pump

I'm pretty sure it's a 390, suppose to be all numbers matching and original...air cleaner has 390 on it for what it's worth... only hat the car 3 days, first day was too dam cold to jack with it, second day, was warmer but it took an hour for the feeling to come back to my big toes... today wasn't bad, tomorrow is suppose to be better. May have to go with the after market pump just so I can drive it once... Thanks for the help!

Look here >>> Ford 390 Fuel Pump | eBay <<<.

The FE engines will all accept the same mount and lever arm, they differ in the fit of the external applications for space and clearance as you've found. The FE engine which the 390 is one of will not cross reference to the small block V8's except the Y block. So the engine family you're looking at is the FE which encompasses the 332*, 352*, 360*, 361, 390*, 391, 406**, 410FE not 410MEL, 427**, 428**.

* Some of these in older applications using a vacuum windshield wiper motor have a dual diaphragm design pump.

** There are high output pumps for performance engines that while they fit ordinary FE pump mounts will deliver too much fuel without a regulator for a standard FE. Also note that 428's came in grocery getters and performance configurations.

Finally got it sorted out, had to find a performance shop to match up what I needed. It turns out that a Carter pump for a 66 Fairlane fits great & works great! thanks all for the help!
