fuel delivery question...

~The Jester~ · 09-10-2005, 11:09 PM

"Brake Specific Fuel Consumption" It takes "X" amount of fuel to make "X" amount of horesepower. It's all physics.

In my opinion you got some fuel system issues. In tank is TOO much pressure, so right there you have to figure out how to get the fuel out of the tank. Granetelli pickup, old school (85 or earlier) pickup....

Stay the hell away from the mechanical pumps. Here again, just my opinion, but the "pulse" they give will make you crazy.

Here's what I would do:
Decent pickup out of the tank.
GOOD Filter, Fram HG-1 comes to mind. FILTER BEFORE PUMP!!!!!
Holley BLUE at least, might want to got with BLACK for the windsor.
Get the fuel to the front via no less than 3/8" line (hard line or braided, your call!)
REGULATOR!!!! Holley makes about the best for what you're up to. Summit's version is no more than rebuilt Holley, so you can save a couple bucks there.
Up to the carb!!!

If it was me, there wouldn't be ANY fuel line smaller than -6AN on the car, ANYWHERE! -8AN would be better.

Hope this helps bro!

would it be possible to put a regulator on the pump that is in there? or is that a bad idea?

Holley makes a regulator to use the in tank pump with a carburetor. I don't suppose it's a bad idea. I would just be more comfortable using stuff that is made for a carburetor. It is not a hard thing to do to make your own pickup. See pic. I don't see anything wrong with mechanical pumps. Like jester said, they will drive you crazy sometimes, though. The thing I have against them is when the car sits awhile, it takes several cranks to get her started up again. I would just get the Holley blue label pump, it'll do what you need. But you HAVE to use a regulator with it. When you buy the pump, it comes with a regulator anyway.
