    There is one sort of.....but not like the old replaceable ones. It's like a mat and is part of the fuel pump sending unit. Barring any problems (..diesel, dirt in tank etc..) it is suppose to last the life of the vehicle. They also no longer have a fuel return line. GM service manual fuel system description for 2008 Impala. The fuel system is a returnless on-demand design. The fuel pressure regulator is a part of the fuel sender assembly, eliminating the need for a return pipe from the engine. A returnless fuel system reduces the internal temperature of the fuel tank by not returning hot fuel from the engine to the fuel tank. Reducing the internal temperature of the fuel tank results in lower evaporative emissions. The fuel tank stores the fuel supply. An electric turbine style fuel pump attaches to the fuel sender assembly inside the fuel tank. The fuel pump supplies high pressure fuel through the fuel filter contained in the fuel sender assembly and the fuel feed pipe to the Fuel Injection System. The fuel pump provides fuel at a higher rate of flow than is needed by the fuel injection system. The fuel pump also supplies fuel to a venturi pump located on the bottom of the fuel sender assembly. The function of the venturi pump is to fill the fuel sender assembly reservoir. The fuel pressure regulator, a part of the fuel sender assembly, maintains the correct fuel pressure to the fuel injection system. The fuel pump and sender assembly contains a reverse flow check valve. The check valve and the fuel pressure regulator maintain fuel pressure in the fuel feed pipe and the fuel rail in order to prevent long cracking times.

    Eldo engine swap

    This pretty much covers it... http://www.northstarperformance.com/interchange.php Dogbones were not used after 2000 except for Eldos....but the holes are there for the brackets. Buried in the details.....a different crankshaft in 2000....."A new crankshaft with a different reluctor wheel (crank position wheel) is used"

    You can get access to the same GM info the dealers use cheap. ACDelco site offers unlimited use for 3 days for $20. https://www.acdelco.com/for-professionals/gm-service-information.html Fuse #29 has a lot connected to it...Also known as 'IGN 1' fuse.

    Where is the fuel filter. My mechanic says there is none.

    I remember when you bought it Marika!, it sounds like it has served you well. Hope you are doing good!

    Yeah, I think it is like a 'fuel sock' in the fuel tank that has a mesh that prevents anything large from making its way to the fuel injectors. Self cleaning, as long as they contaminations aren't too egregious (in the tank).

    That score is the Community reputation and is a sum of Hearts (likes) and Thanks. So to raise that score for someone like or thank them on a post. I suppose it takes a refresh for it to update. I also suppose that critical input would decrease this score.

    Horn question

    On a high note. It is great to have my horns working. Very loud. I forgot to plug in the IAT sensor and could not think of why the Service engine light came on. At least I know that works.

    there is a heart to lower right which enables a like/love response; is that what you mean?

    😀 I even looked on my laptop, I wonder if that feature has been disabled? @Bruce Nunnally what are we missing what happened to the reputation kudos button? 😀

    Horn question

    I have run into it countless times, seems buicks were the worst for it. The horns would not stop blaring. I have seen many with the fuse pulled and if you try to install a fuse it just blows. lol. Nothing like a 4 note going off in the middle of the night to make friends with your neighbors. I have some pics of my repair. You would probably be surprised

    Thanks for the great comeback-I have a steam carpet cleaner that just might be ticket for this job and the Lysol idea is good to-after posting on this forum I went online and found out that there are a few products out there designed for getting rid of the odors- not sure what I will try yet but I will surely use the steam cleaner fist-thanks again

    BodybyFisher, Yes, I was reading in the Haynes/Chilton I have but was looking at an earlier model year by accident. I now understand it is under the intake manifold on the drivers side. I still cannot get to it as I am unequiped at this time to remove the fuel injector wires and valve cover to even get at the intake manifold. I did pull the 30A starter fuse and tested from there and have no continuity between ground and the starter. Again, starting is not the issue, running is the issue. Actually "key on" is the issue because the #29 (rear fuse block) IGN SW 15A fuse is what blows 3 to 4 seconds after turning the key on. I also have the "starting and charging" wiring schematic in the book.

    Eldo engine swap

    Every head gasket job I do I actually drill out the hollow bolt and it's always filled with crud. Alot of times the metal line on the 93-99 northstars are clogged! Always check the air purge line.

    Eldo engine swap

    I have to agree with all of that-I haven’t began to fully track down the culprit in this car-have a lot of other things to do before I can get to enjoy working on her-and I do enjoy it-the guys at work can’t believe that I got the deville so cheap and repaired it without too much money and effort-after all, now an old paving mechanic is riding around in a Cadillac! I learned a lot about the quirks these engines have from this forum and what to check for-all the younger know it alls were saying n-stars are junk and not to buy one-I wanted to find out for myself and I wanted to see if I could fix one-well, I don’t believe that they are junk and I did repair one-now I am a little bit hooked on them and want to get to know them a little better-will be working on the eldo in the near future and I will let you know what I find-my grandkids gave the car the name papalac and I love it-they also had a license plate made up at the fair-gotta love em.

    Sorry but these engines will not interchange.

    It seems DHL has come to their senses and engine is scheduled for pickup next tuesday.. Fingers crossed!! My mechanic also thought he could do it with the engine in, so that's where he started off.. eventually he told me he just took it out, rather than doing snake moves trying to take the heads off.. Once the engine is out, even I could fix the HG's, I suppose.. Earlier I saw him wrestling with the egr sensor even that can basically only be done with the proper tools.. If anybody doubts doing a HG job I can only agree with the above: take the engine out!

    Battery Replacement

    Only thing I would worry about is the monitors, but if you are not due for a state inspection I would not worry about retaining anything. Welcome To CaddyInfo Forum

    Just did a 99 deville in my driveway without dropping the engine with timeserts-can be done but I will not do it again-car runs great and no issues and have put about 3000 Miles on since-have a 99 eldo to do also and will definitely drop engine this time-bought both of these cars for 300$ a piece because people are afraid to work on them-may buy more if I find ones as nice as these-don’t be afraid and take your time-it’s a learning experience!

    The STS has left the family

    It has really served me well. I still expect to see it on the parking lot sometimes when I look out the window.

    What you describe sounds like an intermittent short at the ignition switch or the wiring going to the starter. The Starter on the northstar is in the V in the V8. A continuity check between the starter terminal and ground would suggest a short condition.
