CVR Electric Water Pump Adapters for the FE

Could an aluminum street 45 work? Readily available and cheap.

I know when I did the Summit Kit Rad install it kind of through me for a loop when a stock
lower rad hose did not fit the rad, either did the top, but that was an easy one
I had to make one and it took a bit of doing.
Just something to keep in mind for the customer.

No, the threads aren't the same.  The threads in the water pump are kind of an odd size, 1 1/4" in diameter and 20 threads per inch.  It would be nice if a standard AN fitting would just screw on there...

[fe66comet]

Hmmm straight thread like hydraulic fittings. Strait cut o ring maybe?

[fe66comet]

If it were me I would take a simple approach and weld a bung to the fitting that threads in, might not be pretty but effective. I did the same on my Afco radiator.

From the world of nothing is ever simple.

They do sell a 16an fitting that you could run a 45 or 30 with female AN at each end off of.

Now if you want a clamp on hose you just need to find a fitting to go into the 45 like the CSR.

I think you said the CSR pump was about 1/2" or so shorter than the edelbrock pump (toward the radiator) with your adapters.  If the adapters were made maybe 5/8" longer, would the inlet fitting miss the fuel pump mounting area?

If I extended it out 3/4" the inlet tube would miss the fuel pump mount.  The end of the CVR pump would then extend about 1/2" farther than the nub on the end of the Edelbrock pump.  This would be a good option, except that for one of the alternator bracket holes the water jacket in the adapter would be so close to the top of the adapter that there is no room for a threaded hole.  I could maybe change the water passage location in the adapter to give more room there; I'll have to look at that option.

Do you think that if the pump stuck out 1/2" farther towards the radiator than a stock pump that it would be a problem?

Thanks for the links; there is a short tube listed on the CVR site that would at least allow a rubber lower radiator hose to fit on, I think.  I'll have to get one of those to check it...

[fetorino]

I hope the short hose option makes for an easy fix to run a stock configuration.
For me it would be no big deal since I could run the fitting on the other side.  With a dual pass radiator that would be better anyway.  Maybe something to think of also for anyone running 600= HP won't be running a stock radiator and could run the inlet on the pass side.

[jayb]

Bad news, Rob, the alternator bracket mount on the right side adapter won't allow the tube to clear on that side either.  I didn't think that was an issue when I was designing that side, but I had not considered someone who would be using a two pass radiator.  I'll have to look at that side to see if I can modify the design so the tube will clear.

It's great to get all these issues aired out on the front end of this project; this is a much better scenario than designing the parts and finding out about all the potential issues later...

[afret]

I know in my case with the CSR pump, I had about 1/2" clearance to the fan in the front.  I'd have to measure the actual difference with the Edelbrock pump tomorrow.   

[fe66comet]

I am running an an-20 hose so I will have to make a adapter regardless. My plan is to cut the tube back past the swedge and turn down a bung to fit inside. Then use a strait cut O-ring to -20 adapter . I could have the OD of the bung cut to the same thread but it seems easier to go route 1 and I already have the equipment to accomplish it.

[afret]

Was looking around and just thought about how much clearance the outlet will have from the damper.  I was looking at the photo of the outlet tube near the fuel pump mount and can't really tell from that.

[jayb]

I think there will be plenty of clearance there, but I will check that too...
