Me again. I used a 9 volt battery and a piece of speaker wire. Both link leads work, only one of the old pumps works. Somehow one of the pumps died without damaging the link lead.

I think I will spend the "link lead" money on a new subwoofer! haha

 

OMG.

Was that the hose about 2 inches long with two different
diameters? It can be wiggled off after removing the retaining
ring according to Motorcarman ... and me.

The two clowns doing mine cut it.

Then they charged me the $100 replacement cost.

As an indication of their skill, they had the car for a
month and charged 14 hours.

The link leads are not necessary. I had mine replaced
with Teflon insulated fuel resistant wire ordered from
aircraftspruce.com

 

I was thinking the same thing as you. Yeah Harvest, that was a big no no. I used a small flathead and a can of WD-40 to spray under the hose clamped surface and then they come out pretty easy.

 

The one I cut was a small one that was the same diameter on both ends. I saved the one that has two diameters, and saved the other one too. That one was seized on there! I replaced it with a new piece of fuel line and re-attached the others. The tank is back in the car now and I'm busy re-attaching everything.

 

JTIS said to disconnect the ground cable bolt to the fuel tank. My fuel tank had no ground cable. There wasn't even a place that looked like there should be a ground cable.

What it DID have that was listed nowhere in the JTIS literature was an electrical connection to the base of the fuel tank mounting surface. I've attached a picture, it runs right down the middle of the tank and plugs in just above the spare tire. Is this my fuel tank ground?

 

So I went and filled it up with gas. Started up fine, ran smooth after it adjusted to the hard reset. It felt smooth and fast, but not much different than before. But hey, I was just happy it ran after I did my first fuel tank removal.

Then...I took her on the Interstate.

Oh my word.

I have done 0-90 mph accelerations at the on-ramp before. They are fun, but usually the car seems to settle out and even vibrate a little when it starts to really wind out. Not tonight! It got a second wind somewhere between 3 and 4 thousand RPM. It sounded like a race car revving up to 6,000 RPM and I was doing 90 MPH well before I made it onto the Interstate. I did a few 55-90 accelerations and it was VERY fun. The car has new life at higher RPM now.

I really don't think this is just my wishful perceptions. It's noticeably faster at higher RPM. Like I said though, couldn't really tell any difference just driving around town and getting gas. The additional test will be to see if it starts right up cold tomorrow morning, since the secondary pump is suppose to prime the fuel lines.

 

In that picture wasn't a ground wire. If your car had a ground, it would've been on the left side of the tank and bolted at those sharp seams with a cable going to the body about a foot and a half away. I still haven't figured out the pattern of which models and years had them. It's like if they were built on a Monday or a Friday, they didn't have them. I had the same experience as you did 2 months ago because of the one dead pump. Mine being a 98', both of the pumps were original and were dated 9/97!! And 234K miles. the car woke up after 2 fresh pumps.

 

So the Airtex pump seems to make a very high pitched sound when operating. So high that I may be one of the few people that could hear it. It's not overwhelming and the sound from the A/C completely covers it, but it's there and when there is no competing noise, it kind of bugs me. I guess that's the price I pay for choosing a $50 pump over a $250 dollar pump.

The car drives wonderful.

Any chance that sound will go away as the pumps break-in? It did not make that sound on the test drive last night, only today.

 

Doubtful on the noise going away, but I did give you a lead on a $100 quiet Denso.
As far as your acceleration, yeah, its nice when both pumps come into play.

 

Took the family to the movies tonight. Noise went away. Yay!

I have so much less fear of fuel pump problems now. I bet I could change out the fuel pumps in a 4th the time if I had to do it again. That gives me piece of mind just knowing I can do it myself.

I changed out the locking/latch assembly on the drivers side rear door today, took almost two hours. Did the passenger side rear in about 20 minutes. It's amazing how much faster things go when you know what you are doing. Eventually I'll be able to build an X308 from the ground up, haha.

Also, I think one reason I may have heard the pump earlier is because there is no subwoofer in my car right now, leaving a gaping hole in the rear deck. At least that's a theory. I'll have a new speaker in there by the end of next week. None of us could hear anything during the trip to the movies tonight though, so, I don't know....

 

That is good news, glad I was wrong and that's makes me feel better, and of course your better off...sweet. I think you've got a good head start on that ground up rebuild..lol.
You sound a lot more confident, Jags aren't that hard after all...'ey?

 

The Jag is FAR easier to work on than the Volvo I drove for 5 years. I used to spend hours on Matthewsvolvosite learning how to keep that car on the road. The parts were harder to get (at least for a decent price) and everything was harder to get to. The only upside was that there are a lot more Volvo cars in the scrap yard, so that was a good source of parts. Not the case at ALL for the Jag, at least not in this part of North Carolina.

 

Well, the high pitched whine from the new fuel pump was back for the drive to work today. I guess it's possible that when the subwoofer is back in place I won't hear it, but I suspect I still will. The odd thing is that about half way home from work it stopped, and in the garage at home I could not hear the fuel pump. How would it come and go like that? Did I mount the pumps wrong? Are they just noisier pumps? Is my fuel pressure regulator going bad and restricting flow? The fuel filter is only a month old.

I was going to test the fuel pressure tonight after work, but I was just too tired and the schraeder (sp?) valve is not easy to get to on the XJR. It was very easy to access on my XJ8. Maybe I'll do it tomorrow night. Car still drives great.

 

Update: I put a towel over the open subwoofer hole, can't hear fuel pumps now. Maybe when I install the new speaker next week I will never hear that sound again. I took the speaker out during the fuel pump installation, so for all I know the old pumps made that sound too. Or, at least the one that was working, haha.
