Re: electric water pump heater hose routing Q?
![]() ![]() You can buy a tee, I think it was a chrysler product, or you can have mine since I'm not using it. I didn't like the way the 5/8" hose would be routed. I plan to weld a bong to the tank and just put a barbed fitting in it. Also I want to flip my heater core upside down so the outlet has a shorter lenght to the rad.

Re: electric water pump heater hose routing Q?
i'm thinking like you are, jaros.
i'd really like to have a direct route from my heater to a tank or even the rad. i think i'm going to hold off on running the hoses for the heater until i decide if i want a mohave heater to replace my pretty tired stock system. anyone else have any routing suggestions?

Re: electric water pump heater hose routing Q?
well... looks like it's just you and me, jaros! guess we better make a good thread, so when people search in the future, they get tons of pics and info
![]() looks like you're using March brackets (PN 22007?) did you have to drill and tap for the alternator mount? i've got a late 60's 327sbc, so i always worry about little things not lining up like they do on 350sbc's. i've been looking at these fans from FAL: http://www.flex-a-lite.com/auto/html...-electric.html what are you using for fans?

Re: electric water pump heater hose routing Q?
that's easy enough information to find on CSR or proform website. but in the interest of actually establishing a good informational thread, with good results for rellevant search terms:
belt driven water pumps, found on most people's engines, require the engine to work the pulley. the engine only makes a certain amount of horsepower, so if some of that horsepower goes to turning your water pump... wouldn't you like to have that horsepower back? so it can go to your wheels? basically, if you have an alternator that can handle the 20+ amp draw of an electric water pump, then you can gain a little efficiency in terms of horsepower to the wheels, or in terms of fuel consumption related to miles per gallon. i have a big 4x4, and i need every mpg i can get... so elec water pump, and elec fans are good options for me. but if you are not "squeezing" power out of your motor, then there is no need. if you just want more horses, you can find many better modifications.

Re: electric water pump heater hose routing Q?
Nice info man, what about looks, do they look the same as old style? I am removing my fan going with electric, i already have ordered a bigger alt. Do you gain any room buy going with electric water pump?

Re: electric water pump heater hose routing Q?
i'd have to say that nothing about electric h2o pumps or electirc fans retains the stock looks.
the elec water pump is roughly equivolent in depth to a sbc long water pump (about 7" from mounting surface to face). the real changes you will see in looks are the lack of a pulley and the change in alternator mount. when you install an electric water pump, you have to also install a mid-mount alternator bracket system. the normal high-mount alt system will cause your alternator belt to interfere with the new water pump. (this is the March #22007 i questioned jaros about) in regards to the stock fan to elec fan conversion... the difference in appearance is huge. the stock fan and fan clutch assy is completely removed, so there is now an obvious gap between your engine and fan shroud. the stock fan shroud on my sbc is probably over 6" deep. the fan shroud on electric fans is between 2-4", depending on if you go with a low profile fan or a normal 'universal style' from Flex-A-Lite, or SPAL. i cannot speak on the depth of fan and shroud assy's from other vehicles. IMO, the new sight of an engine with less pulleys and belts, together with the actual ability to see the entire front of your engine is just tooooo cooool. i always hated working around the stock shroud and fan, and i look forward to being able to clean my engine bay with much less hassle.

Re: electric water pump heater hose routing Q?
FYI,
the water neck (thermo housing/whatever you want to call it) from a late 80's chevy pickup has two extra inlets. one is for a vacuum switch (EGR stuff) and the other works well for screwing in a 3/4" nipple and directing your heater hose to. problem solved ![]() autozone can get chrome ones too! FOR JOY!!!

Re: electric water pump heater hose routing Q?
What is the average life expectancy of an electric WP? I worry about reliability.

Re: electric water pump heater hose routing Q?
proform (the one i have) is 2500+ hour life expectancy, and proform can reman them for a decent price.
meizure has a pump with 3200+ hour life expectancy everyone has a different opinion of if they will hold up to the test of time... i can only say that mine has run about 30 minutes so far with no problems :P

Re: electric water pump heater hose routing Q?
My alt. bracket bolted rite up to the 350 head, there is a small issue with the tensioner rod under the alt., seems like they counterbored it from the wrong side. I've asked March to send me one off the production line that wasn't bored and I will fix it..
The main reason, besides cleaning up the front of my engine, is space. I plan to run an OD trans, and now I can shift the whole powertrain forward 3-4 inches My concern is the elec. motor will quit and I won't see it, so I have to put an idiot lt. on the dash that will get my attention, you can miss a gauge climbing very easily! I think DC motors are reliable, brushes and bearings being the only thing that can fail. Mine has a 1 3/4" outlet on my pump, and I want to change it to 1 1/2" because it mite be hard to find the rubber adapter on the road We'll see how it works out, can't say, as mine is a Garage Queen for the last 5 years, but if it doesn't I can switch back to a conventional pump

Re: electric water pump heater hose routing Q?
Well... Umm.... Kinda....
I'll have to search my puter. My camera phone just makes noise when I want to use the camera function... ![]() So... as far as the late 80's water neck... The upper rad port is angled lower than on a traditional water neck. Thus focing me to relocate the water temp sender on my Edel Performer mani. I haven't started working on the truck again yet (it's 20* out right now), BUT I'm considering using a water neck spacer (1" aluminum from Jegs or Summit). Initially, I just ran an inline temp sensor housing in my upper rad hose, but then I couldn't find a 1/2"npt or 3/8"npt temp sender with the right ohms and sweep ![]() So, I've got this kinda bling aluminum inline port now, which I'm considering using for a Flex-A-Lite temp sender to control heated seat switches... or... hmmmm

I vaguely recall a single extra port on a water neck from Summit... but it's kinda foggy now... been a while. I did just plug my extra port. I just bought a NPT chrome plug kit from auto-zone. I got a couple each of four or five different sizes. They've already come in handy. I then plugged my water temp sender port, and my two new ports on my inline temp sender... ![]()

Re: electric water pump heater hose routing Q?
I found this one on the Autozone website - looks like it might work well. I put in 1981 GMC C1500 2wd 1/2 ton 5.0L 4BL OHV 8 cyl in the vehicle details. It is Spectra p/n 4730

I have not had my engine running since then either... BUT, I did run the electric water pump and my electric heater with the key in the accessory position. It circulated well, and I could hear most of the bubbles flushing out. Whether or not it will all explode when there is water pressure and circulation through the block remains to be seen ![]()

![]() Mistake in the 3rd pic. is that I made it up using a 1/2" NPT bung, for a -12 AN (5/8") it needs to be a 3/4" NPT. So back to the drawing board ![]() ![]() ![]()

Re: electric water pump heater hose routing Q?
For some reason I had the wrong flow direction in my head, read another thread that shows the right direction. I think your setup may very well work, plus it will give you another area to bleed off trapped air in the cooling system. Keep us posted as you make progress

Re: electric water pump heater hose routing Q?
Dangit!!! Now I've got this unexplainable urge to finally fill a tank with some Helium and start plumbing with metal instead of rubber.
Kinda off topic, but your ballin' aluminum fab work makes me think of a rod plumbed with copper.... looked sharp. Your aluminum look snice, but you might want to consider finding a source for a 90* street T I know they are avail in copper and iron and pvc and stainless... So I bet you could find one. A street T would have a bit of elbow to the inlet. It would actually flow the coolant into your water neck instead of the abrupt 90* it makes now, and I think it might look cleaner. I bet if you look hard enough you can even find them with the correct male/female/threaded combination you need.

-12AN/ 3/4"NPT drilled and tapped into my waterneck, 45 degree -12 fitting headed at the heater core. At this point in time everything will be push on fittings The inlet for the electric water pump will go back to stock. All my hoses should look like my power steering ![]()
