Hi guys and gals
Looking at picking up a '74 164E, turns out the fuel pump is bad (along with a few other things), before I go and invest in the car, i would like to know:-

-What pressure does the fuel pump run?
-Does anyone carry an original fuel pump?
-Will a "generic (e.g Carter/Universal)" fuel pump of the right pressure (with some fitment mods) work?
-Any links, experience, knowledge base stuff would be appreciated.

Thank you in advance.

Is the 74 K jet (I can't remember the transition year from D jet to K jet)? The D jet runs at 28 psi, the K jet is a lot higher - can't remember the exact number - something like 90 - 100 psi?.

The original Bosch pumps are out of production. You can find rebuilds / refurbished pumps for a pretty high price. The generic electric pumps meant for use with carburettors will not work; however, you should have no problem finding an aftermarket pump. Try Iroll motors, VP auto, Scandcar, CVI, Skandix, High Performance Auto (all Volvo specialists) or even Rock Auto. I got an Airtex replacement for my D jet fuel injection. Required a little fiddling to mount it; but, it has worked fine so far. Depending on who you buy it from the price is in the $80 - $120 range.

Rotary vane fuel pumps don't make pressure, they just generate flow. The pressure at the injectors comes from the regulator opposing that flow. So, any pump that flows enough fuel --which is pretty much any pump of that type -- will work. The challenges in using a non-stock pump are mounting it and adapting the fittings to suit the car.

D-jet runs at 30 psi -- some manuals say 28, but Volvo updated that to 30 at some point.

Pretty sure the '74 164E is a K-jetronic. My '74 142E has the K and yes, the pressure is much higher.

The 164 never got K-jet -- injected ones were D-jet to the end. 140s went to K-jet for the '74 model year, and that carried over into the early 240s.

Add that to your Volvo fact file. It will come in handy at the next round of Trivial Pursuit - The Volvo Edition!

Another bit of trivia: The '75 164 was sold only in the U.S. market (and maybe Canada?). The rest of the world got the 260, but the PRV engine wasn't "federalized" yet -- Volvo had enough to do launching a whole new line of cars and engines without dealing with that -- so we still had the 164 because they still wanted to offer a 6-cylinder car. There was also a lot of "year only" stuff. I've heard they're sought after in Sweden as a rare model.

'75 was also odd for the US 240, many of which got the B20F engine when they were supposed to get the new B21. Good times, huh?
