Default Fuel Pressure problem



I recently converted my 19914cyl Coupe to a 5.0 Carbureted setup. We are almost done with the conversion but we are having problems with the fuel pressure. i have a $100 Mallory fuel pressure regulator but the pressure is still to high. What do you guys recommend. i have been told by a few techs to go buy an intank electric pump that is already set up for the carb. What should I look for? I plan on changing the 7.5 rear end out to the 8.8 I have in a few weeks so I will go ahead and drop the tank while we're at it. I heard that I can get a mechanical pump for it but I'de have to get the welded place in the block punched out</P>


P.S. I'm going to the beach as of 2:00 am tomorrow morning so i won't be able to reply after then until next weekend. But I'll be on and off tonight. Thanks for any advice</P>

Default Fuel Pressure problem

A few months ago i put a carbureted 5.0 into an '89 lx, i took theentire 4 cyl fuel system off and trashed it. I usedan 82' mustangfuel tank (it only has a pick-up tube and fuel level sender in it), a holley blue pump (it's an in-line elec. pump, max pressure is around 14 psi) and the regulator that came with it (set it to 7 psi), then ran newlines to the carb (don't forget to use a good filter). You can just use the pick-up tube out of any carbureted 79-84 mustang in your tank, i think the hole sizes were all the same. Also GMS makes a pick-up tube assembly, they call it a fuel tank insert, it will work for you too, the jegs part number for it is 467-GMT17998. I would definitely go this route, popping a hole in the block and using a mech pump wouldn't be a good idea. Hope i helped. Later.

Default Fuel Pressure problem



Ok i'm back from the beach !</P>


ok cool. I'm going to check and see if my uncle can get mean older pick-up tube and the sender.Do ihave to just use the fuel level sender that is already with the tank and bypass the one I have now?Is there any wiring I'm going to haveto do?I wish there was a way to get around having tomess with the pick-upbut i read on another webpage that it was what i needed to do. I wish i could just get another pump and be done with it. Actually I wish that freaking regulator I bought worked. It was awful expensive and it sucks that It is useless now. It looks nice though I guess<IMG src=smileys/smiley6.gif border="0">. Do you think i should go with the GMS deal? Oh and how much was that fuel pump you got? Thanks for the help by the way.</P>
