Question on 67, 427/400 fuel pump hose

[Thomas S.]

I replaced the fuel pump on my 67 427/400 car with a AC logo 40482. The prior pump did not have the logo and was leaking. When it was top-flighted it had a deduction for the non-logo pump. When I removed the rubber fuel hose from the pump I got a surprise in the form of a tiny red spray extension tube inside the hose, the type used on WD40 or other spay cans.


In the process of looking for the correct rubber hose replacement, I found that this hose had been updated to a molded type (S-shaped) on subsequent years and the reason was to avoid kinking. I realize that for 67, the molded hose would not be correct.








Finally, if there was a potential for kinking, would it be a bad idea to place a small diameter solid SS wire in the hose to maintain the shape or am I just being overly cautious?

Stopped using Ethenol fuel in all my older cars. The deduction I received was for a non-AC pump with no mention of the fuel line which was basically typical tubing with no marks, or marks removed. Thanks for the suggestion on the tubing.

You can use a piece of stainless spring in the hose to keep it from pinching closed to keep your points. VS an S molded hose. Better than using plastic.

Ditto to Mr Westbury. There is a long list of questions at every checkout, but otherwise no hassles dealing with them at all. In fact, and this is just my personal opinion, I would rather deal with an independent business than the several big guns that are left having bought out some of the original suppliers.

The question about NCRS membership also allows them to make sure you are getting a "correct part". I had order something recently and got an email from them letting me know that the part was a repro and might not pass judging. I had already known that, but I doubt any of the big suppliers would have gone that far.

This hose was removed from a 67 427/400HP Vette with less thIMG_0858[1].jpgan 5000 miles. Hope you can make out the numbers. JRIMG_0857[1].jpg

JR,

Are there any ribs on that original hose like the hose that DR entices people to buy by highlighting that feature?

The tubing with the 3-grooves is identified as correct in the 63-64 TIMJG but there is nothing specific in the 67 version.

For 63 there are actually 2 different p/n’s for the pump to hard line (3828882) and then 3830780 for the tank to hard line

For 67 p/n 3751442 for the pump to chassis fuel line with same (3830780) for tank to hard line.

this stuff will drive you nuts.

No ribs! Just the stamping: 3/8 GM6107M*H*KV Green clamp with flat ends

guys...
from having been in the GM lab responsible...
I saw the prints, all rubber hoses had a chart that identified suppliers, so all hoses had rib and or stripe configurations.
no speculation - just the facts

Yes I would love to roll back 45 and get access to all that fine detail again.

and on the part of the line to pump hose, why would a big company go to all the expense to engineer, test, source and pay for a separate hose if the 327 version was able to be used? They would not have - so...what was the real difference to the 327 hose???
