Pulsators are about 3-5 bucks at your local auto parts store. Usually in the HELP section. When I did my last pump I added one back in and was amazed at how much it quieted down the pump. I was trying to minimize the fuel pump noise as much as possible. Upper and lower rubber isolators, foam fuel pump sleeve, and pulsator. I have to really listen to hear the pump with the engine off. I can't hear it at all when the engine is running... unlike my 84. Something to take into consideration at least.

EDIT: Oh. I also used the caddy fuel pump relay which is nearly silent.



I have poor hearing as it is now. I like to be able to hear the pump prime when I turn the key on.
But thanks for the information

I built my fuel lines today and took them to the welding shop to get them brazed togeather. I removed the ends of the Fiero steel line and cut it off about 6" from all four ends. I went to the parts house and purchased 2 5/16" line nipples, and 2 3/8" fuel line nipples. I also purchased a 3/8" and 5/16" steel brake line. I cut ther ends off of the steel lines and bent them to fit on top of the passenger side rear frame rail to the trunk bulkhead. There I made a 90* turn to the center of the trunk. When I drop the engine for the new oil pan gasket and to fix the waterpump inlet I will hard mount these to the car. I'll post pictures when the welding shop is finished with the brazeing. I am going to need one foot of 5/16" and 3/8" Goodyear Fuel Injection hose to join the lines to the inlets to the fuel rails. I cut and reshaped the Cadillac fuel lines to point to the center of the trunk. I had a nipple brazed on the end of these also.

Just for information: Autozone sells the Goodyear Fuel Injection Hose with the blue liner. It's about $5.00 a foot, but do not use regular fuel hose for high pressure applications.

McMaster-Carr sells the Fuel Injection Hose Clamps. I havent been able to find these anywhere else local. Packages of 10 each

I am still shooting for a fire up next week some time. I have almost all of the wiring harness stuff finished up, tied out of the way of hot things and am working on the fuel system to get it up to speed. I plan on installing the cooling system next after the fuel is good to go. I have a 14" piece of tailpipe to attach to the rear exhausr manifold so I don't torch the forward trunk bulkhead.

Ordered the new water pump inlet from WWW.GMPARTSDIRECT.COM
$55.00 shipped. More in the kitty.

Wires are on their way as of yesterday. Can't wait to hear this thing. Oh BTW, the reason the hoses point different is I bet the sending unit is from an earlier car. The fuel lines from my 87 coupe are the same as 87 GT BUT are different from an 85 GT. So I would go that they replaced that sending unit with one from an 84-86 (like the interior).
You sure you don't want me to cut out those sections in case you ever want to replace them? LMK
Have a great weekend!
Steve

When life gives you lemons, thank them for the Fiero.

Thanks for the insite as to these differences. I will also look at the depth of the two and see if there is a difference there. I didn't even think to look at that part of the equation.

Next week would be a good time for you to come down and take a look Steve !!!

Go back to my first post in this thread and look at the items I listed and the cost incurded so far in this swap.
Joe

Edited to add: The old one I removed with the black silicone falling off is 1/2" longer than the other one I have to use as a replacement.

Today I went and purchased an inline fuse holder. I soldered a purple and a pink wire to one end of the holder wire and put a male blade on the other end.

On an 88 there are two female ing sockets on the bottom left of the fuse box. There are female sockets on the rear side of this same spot accessable from the rear. I plugged in the flat balde and two new ingition circut wires were created.

I put a 15 amp fuse in the inline holder, but have decided to switch it to a 20 amp tomorrow beccause I am running two circuts off of the one fuse.

I ran the purple wire to the torque converter switch on the brake peddle, then down hill to C203 where I spliced into C203 'P'. My car was a stick shift so this was an empty socket on the engine side of the connector. I added a pin into the 'P' socket, and wired it in to the transmission round connector pin 'A'.

The pink wire I implanted goes to the C203 'A'. This socket was empty on my 88 coupe, so I am going to use it for +12V ignition feed for the shift solinoids on the round transmission connector pin 'E'. I added the male and female pins to the two halfs and finished the wire to the round connector.

I have tried to keep the colors corrrect for added circuts for this swap as much as possable. That is the good thing about having this nice pile of extra wire removed from the Cadillac harness:


Tomorrow I am going to reinstall the fuel tank and blow out the fuel lines before I hook up the lines to the tank. I am going to put 2.5 gallons of fuel into the tank after it is installed so I can see where 2.5 gallons is indicated on the gauge before any more fuel is added.

I want to go over all of the engine grounds before I proceed from there. As I have been reading other members problems from after install with shifting and other type of 'Bugs', it seemed that poor grounds or not connected grounds were high on the list of 'Fixes'.

I am gonna take a copy of the wiring diagrams and circle all of the grounds with a green marker. Then go out to the car and find and check them all off before proceeding.

Getting close tp first start up

Well today wasn't what I wanted it to be. One steep forward, two backwards it seems.

I fit the new V6 fuel pump on the metal pipe thingie, and put it all back in the tank. Fit the tank back under the car, and hooked everything back up. I got out from underneath to power up the pump and saw the new fuel pump strainer sitting on the front windshield. I said a few profane words. Picked up my tools,cleaned up and went to A-Zone to get one foot of Goodyear blue lined fuel injection hose.

On the way home I found a 2 foot X 1 foot tool box in the middle of the road.

Gotta a smile on my face at the end of the day after all. It just wasn't from the sound of an American V8 roaring in my garage.

Dropped the tank this morning and put the fuel pump strainer on the pump. Back in the car now. My back is giving me fits now from being on the cool concrete floor in my shop.

I replaced the fuel filter while I was underneath the car. No telling how old it was, or what was inside it. I blew out the return line and supply line with 120 lbs of air pressure before I put the lines back on the tank. Don't need a dirt dobber nest in the fuel rails or pushed into the gas tank. I am gonna put two gallons of gas in there tomorrow, prime the system and look ofr leaks. I want to see where the gas gauge reads a 2 gallons of fuel also.

This is as low as I could get my fuel gauge to read. I played with the two adjustment screws for about 10 min's:


Some of the tools I found yesterday. I trashed some of it because they were rusted to bad, or of soft cheap Chineese quality:
A few of the end wrenches have the ratchet built into the box end of the wrench. The brown thing on the right of the top picture is a Swingline electric stapeler.
