Question

=20

What is the fuel PSI with the Ford pump?

=20

I plan to put a 4.3L TBI (1227747) onto a Jeep 4.2L. I have a parts =
vehicle,
but still need an external fuel pump. Think the Ford will work?

A good cheap fix for a fuel pump is a Ford truck frame rail pump (not =
the
tank pump).  They were used in the late 80's and early 90's.  Cheap and
durable!  Cut the tubing long and use the Ford connectors and pump =
brackets.
I slipped my OEM fuel line and filter over the Ford stubs and welded =
them
together.  It was probably the easiest part of the swap.  I'm using =
stock
3/8 and 5/16 lines.  I don't have any fuel delivery issues at all.=20

=20

I swapped a 90 camaro (730) into a 72 GMC 1/2 ton.  My TPI was =
originally a
MAF system from a late 80's camaro.  Changing the harness around from =
MAF to
speed density is possible, but it takes a bit of work.

=20

Hopes this helps.

Hey, a local guy!
I'm new at this, too, and can't help at all on the drivetrain stuff, but
here's what I'm dealing with on my swap (7730 + TPI -> 340 + 69 Plymouth

Fuel delivery - seems that even a 5/16" line is OK for a return line, =
I'm
going to 3/8" on the feed. If you've already got a 3/8" feed, you're
probably OK to use that as the feed unless you just want to have a =
larger
line. I'm planning on using the aluminum tubing from Summit/Jegs and =
some
AN adapters.
Fuel pump - The pump I have is a NAPA part, if I recall. I suspect it's
actually a reboxed Walbro or something. Here's another local (Garland) =
guy
that sells fuel system parts:
http://www.autoperformanceengineering.com/
NOTE: you didn't mention it, but you'll probably have some fuel delivery
problems at low fuel levels in your stock tank if you're not planning =
on!=20
some sort of sump or surge tank. Even some fuel cells have this problem.
There isn't any reservoir in EFI like there is in a carb (bowls), so if =
the
pressure pump sucks air, it's not pushing anything until it recovers. =
I'm
looking at a couple different types of surge tanks. Check the previous
posts for the last few weeks for details.
Harness - I'd like to know if there's an adapter for the Vette box, too.
I'll be mounting mine inside the car, but would like to be able to mount =
it
in the engine bay. Not a big deal, I'm running out of space up there
quickly.
Hope that's some help,
