I have a 68 144. Is it possible to rebuild the fuel pump or do you replace the entire unit? My pump has a cap on top with a screen inside. My concern is the age of the diaphram. If it can be rebuilt are there still kits and where would one buy one? Thought I might rebuild it just to be sure.

I just ordered a new mechanical fuel pump from the FCP Groton store on Ebay. It cost $41 including shipping. They've got more left at this price. While it may be possible to rebuild these pumps, the repair manuals I have say that when they fail, they should be replaced complete (minus the spacer, of course). The price of ~40 bucks for a shiny brand new pump with a new gasket may just make it worthwile to bolt in on and save time and effort. These are oem style mechanical fuel pumps designed for a variety of old Volvos including 1967-1974 Volvo 140s. Good luck!

Hello,
The pump FCP sells will most likely put out too much fuel pressure and I will not use them.
I insist that my customers use the Pierburg pump available right from Volvo, which I keep in stock or rebuild their original A/C or early Pierburg pumps which I also keep in stock.
I do this mostly to prevent the float bowls from overflowing gas onto the exhaust manifold to keep a potential fire from starting in the first place.
Can you believe it, but customers kind get pissed off if you turn their car into a fire bomb!!
So go ahead and use the FCP pump, but get a good fire extinguisher to take along with you just in case.

are the scantech pumps any good, and why not to use the spacer with them?

Where could one get kits to rebuild the Pierburg or A/C? Does Hi Performance Automotive Service have a web site? Do they provide service only or also sell parts?

Hello Craig,
No website yet.
I own a repair shop in the Los Angeles, CA area in the city of Torrance and provide parts and service, mostly for rear wheel drive Volvos.

Eric,
I was unaware of the defects in FCP Groton pumps. In fact, I'd purchased from FCP because of their products' general good standing in this forum. Thanks to your advice, I'll be extra vigilant for problems. If problems do occur, I guess I'll be forced to go with a new Pierburg pump or just live with the one I've got. I was going to install an in-line fuel pressure guage after the FCP pump. Since I've already ordered from FCP, can you tell me how much fuel pressure is normal for 140s?
BTW, I always carry a fire extinguisher in the back seat. For some reason, past experiences with smoking brakes, red-hot wiring, melting antennas, leaking exhaust, and smouldering manifolds have made me a little nervous :/
Regards,
B.C.

Hello,
The deadhead pressure on a new Pierburg pump is a little less than 5psi so I always keep the pressure below 5psi.
When I have to deal with an overpressurizing pump, I will set the pressure to 3psi and then check for starvation by taking a run at least 70mph for a couple of miles.

I'm using one of the FCP fuel pumps (made in Italy with a replaceable diaphragm) without a pressure regulator because I wasn't aware there was an issue. That said, I've had no other problems with it, except that it revealed a fuel hose that leaked because of clamp wear. I have a Pierburg on another car which hasn't given me any trouble either, but at start-up this Spring one of the bowls flowed over, which had never happened before. Adjusting the float a bit and making sure the needle tip was clean fixed that. I have a feeling that the FCP pump (the same, BTW, that ipd sells for about the same price) shouldn't give any problems, even without a pressure regulator, as long as the float valves are in good shape and the floats themselves properly adjusted. Of course, time will tell.

I have used the FCP fuel pump.
Yes it did put out more pressure than SUs require. I think around 5 or 8 psi or so. I did check it with a gauge, but just don't remember the exact figure.
HOWEVER, I have an in-line fuel pressure regulator to reduce the pressure to only around 1-1/2 psi. Of that, I am sure.
Given the choice, I'd also prefer a Pierburg pump that only puts out the lower pressure. But at the time, I needed an inexpensive replacement in a hurry and already had the fuel pressure regulator.
I do not fault FCP for carrying them, and I also carry a fire extinguisher in all my cars. Not just the old ones.

Tom,
I have no experience at all with fuel pressure regulators on mechanical pumps, although I have done quite a bit if fiddling with the ones on D-jets which, of course, work in conjunction with the return line. What type/brand are you using?

Hi Bob,
Pretty sure it was made by Purolator.
I picked it up at a local speed shop a few years ago.
Think it was around 25-30 bucks.
Summit or Jegs probably carry them too.

Hello,
Which exact type of fuel pump?
A picture would help.
