Is there a mechanical fuel pump available that puts out 15-20 psi for the FE engines? Can't see to find one in my searches

 

Why? your not running EFI are you?

 

No, I would like to do a blow-through carb set up. I can obviously run an electric pump to achieve the fuel demands but I'd prefer to stay with mechanical

 

15-20 psi would translate to either a lot of force on the fuel pump eccentric, or a lot less fuel flow as it would require more mechanical advantage on the fuel pump arm. I'm not sure anyone ever engineered a mechanical fuel pump with that much pressure.

 

Hmm I hadn't thought about the effects of increased wear. I'll have to look into that some more

It was either summit or jegs had some listed for small block fords and a couple of chebby engines but nothing for the fe's. The look similar but its hard to tell differences without holding one in your hand.

The volume looked pretty good though, a 16psi pump for a 302 is listed at 225 gph for a holley pump on summit. I wonder if it could be retrofitted

 

16 psi fuel pressure would probably be adequate for what I want to do, looking at 6-8 psi and I've heard you need about 1 psi fuel pressure for 1 psi boost added

 

<p>Actually, I thought about it some more, and what is it, twice the load? And only when you really really need the flow? Probably just not enough of a demand for an FE pump...</p><p>&nbsp;</p><p>&nbsp;</p>

 

Pretty sure you're right on both accounts. Certainly haven't heard of a whole lot of forced induction FE's floating around, and those who have probably are using electric pumps.

I have to be difficult though

 

Google search 'boost referenced fuel pump' you can modify a stock pump to do what you need.

 

Awesome, thats exactly what I needed, thank you

 

I would just save yourself some aggravation and run electric. I had a TON of problems with the pulling truck and the mechanical pump and heat transfer into the fuel. Worked great on the first hook, but on a hot rehook it caused all kinds of fuel boil.

 

Hmm thats interesting. Was it vapor locking and going lean? Were you running a lot of PSI? I'm only looking to get probably about 5-7 psi of boost pressure

 

It was boiling the fuel before it hit the carb. I think it was transfering too much heat through the pump into the gas. It was fine until the rehook and it would just sputter out. Now this was a N/A motor. SO it would be even worse with a turbo where you have to have the fuel. This was with the 140gph mech. pump

first hook.
Rehook in pull off.
