1970 CST Blazer, have you used that line on a 1968 with a 250 and 1MV carb?

Here's the challenges I found when looking for a line. Many list that they work for 1967 and later, but the carb changed from the 1BV to the 1MV in 1968.

Fuel line goes in the front on the 1MV and in the side on the 1BV.

I just went and looked at a couple vendors to see if I could find a line that looked right.

Even GMCPauls lists a line with this description "Pump To Carb Stainless Steel Line Inline 6cyl. 250ci or 292ci 67-70 Chevy / GMC Truck, 69-70 Chevy Blazer / GMC- Jimmy 2wd" This description can not be right for at least 2 reasons, #1 Different carbs in 1967 to 1968 and #2 the fuel pump on the 292 is located further back. So, no way in hell it works for 292 and 250.

I went and looked at my line collection and I have one that will work for a 1967 250 with 1BV and another that will work with 1967 292 with 1BV. I have a third line that I remembered will fit my 1968 with the 1BV, but won't work with my HEI distributor. I wish it had a part number on it, I'd let you know what it is.

I checked inline tube and classic tube(the picture of the one 1967cstblazer posted is very hard to tell if it looks like my line that would fit.) I looked at classicparts.com and they don't have pictures of all of their lines. I'm 90% sure the line I have that fits 1967 292 with 1BV came from ClassicIndustries, I think I bought it in their showroom in California.
