what are these holes and i notice alot of people run their fuel lines with rubber hoses(the fuel injection hose) but what are you doing to barb the ends or are you just cutting them and adding hose and clamps..seems bit unsafe? and what filters are you running before and after you elctric pump(those with inline pump) i'm sooo close.. tomr i would like to get it running.

The hole on the right is the PVC port. Normally there is a nipple threaded into that hole, and the PVC line runs from it to the valve on your valve cover.

No idea what the hole is on the left, I'll look at my intake tommorow and let you know.
 
I agree with Sierra,PVC port.
The bolt hole is just used for the manifold bolt,no bracket that I'm aware of.
 
thanks guys..
for those of you with inline pumps what filter are you running before the pump?
crap..one more Q's...what the hell do i do with the park nutral sfty switch coming off my comp? my 75 just has a th350....rrrggg
 
Park neutral switch is on the foot of your steering column. It keep the engine from cranking in gear. The wires for the switch are yellow and purple. You'll need to connect the ECM to the purple wire.

Same goes for a standard transmission, cept you use the purple wire off the clutch switch.
 
I use 2 filters. 1 prepump, 1 postpump. You can run any inline filter before the pump but after the pump you need one rated for FI. I am using a clear Fram G3 filter prepump and a filter from a 92 Ford F350 w/7.5L motor.

The fuel lines on my motor are rubber like you mentioned. There are special fittings (saginaw to AN) fittings that you can buy to convert the fuel rails fittings from GM Saginaw style to AN fittings. After you convert it to AN you can put AN hose barbs on there and you have some nice safe connections. Some people cut off the fuel lines and flare them to put lines on and that is kinda sketchy to me.

sweet..thats what i thought. i have most of fittings including to convert to AN. and i just figured out that one could actually double flare themselves(i would only use that for before pump or even parts for return)

thanks for the help you guys.
 
Yes, I know this is an old thread, but I did not want to start a new one. Where can I find the sizes for AN fittings? In other words, is AN 10 about 3/4 of an inch in diameter?

Also, I hear that running a filter before an inline pump could lead to fuel starvation and a short life for the pump...thoughts?
 
Your pump already has a filter before it, the sock filter in the tank. And yeah, it is hard on the pump to have one there. Pumps are really good at pushing fuel, but suck at pulling fuel, so if they have to pull fuel through a restriction like a filter, it will make it work much harder than it needs to.
