Do any of our sponsors sell Walbro FP's. I don't ever plan on doing massive work to my horsepower production, so a 255lpr is not important to me. I know it's not much more, just don't feel I'll ever use it.

Call Gyrhead (Paul). He advertises that he has them.

As for the 255, put it in. You are going to do all that work anyway, and if you ever part with the car, it's just one more selling point.

A couple of things to note:
1. Use a brass drift to loosen the locking ring for the sending unit. Spark+gas fumes=evening news. If you can get 2 of them and a friend help you, space yourselves out 180 degrees on the ring and you should have it out quicker.

2. Use a generous amount of petrolatum (KY) on the filler neck grommet to ease installation, and to keep from damaging it. Put a new one in while you are there, it's a cheap investment.

3. Buy extra locking clips for the fuel lines. They are about $4 for a box of 6.

4. The fuel filter to replace the inline pump is from a '93 Ranger, if I remember right. I did a search one day for it....the info is there.

5. Be prepared for the possibility that you may be replacing the tank too. After 20+ years the inside may look like a relic brought up from the Titanic.

Navy,

I asked Paul at the reunion and he said he only sold gas tanks. I will give him a gingle or browse tho. I don't plan on selling the SVO anytime soon, as I usually keep my cars 10 plus years and I've only had it 13 months. Had the 68 12 years. Anywho, I may go with a 255, buuuuuut, I'm still not convinced. Thanks for the advice bro.

I spoke with Paul about .....not quite a month ago, and he has just updated his webpage, and expanded his inventory, to include pumps. It's a toll free call too.

ALSO, see my edit on my first response.

**Californiadreamr** · 12-23-2005, 11:00 AM

Navy,

I stand corrected, Paul has them on his site, you just have to call for price. That's always scarry. As a retired Air Force vet, I had to disagree with you originally, but in the heat of battle, comraderie prevails as usual. Thanks bro!

ok --
My thought on the pump is -- in 10 years, my 255 will still be making 190

if the tank is really almost empty this is a piece of cake..

first off -- don't take any screws, or anything loose around the fuel cap.

as always remove neg. battery cable
release fuel pressure
Put the rear of car up on 2 jackstands
Remove the small screw on the bracket that holds the filler tube on the side of the fuel-tank
at this point, it's a good idea to spray a little lubricant on the gasket where the fuel filler tube goes into the tank.
towards the front of the car, ther are 2 (I believe 15mm) bolts, that hold the 2 straps to the frame -- start removing those
as the bolts come out, the tank may (or may not) start to lower
once you get the bolts out, you can drop the tank. You only need to worryabout disconnecting the wires before completly dropping the tank if you have the car up on a lift.
once down, unplug all the electrical connections, and the fuel use a brass punch (something that won't spark) to turn the locking ring, once out, snake the fuel pump out through the hole.
On your car-- (84/85) there are 2 things that need to be replaced -- The fuel pump bracket, and the GROUND WIRE. Neither of these need to be replaced on 85.5/86 SVO's
so -- either replace the pump bracket, or modify the existing one to work,
replace the ground wire to the fuel pump (use a good 12 gauge or so wire, and ground to a good location on the frame)
re-install the tank (reverse of removal) inspect the tank gasket, replace if necessary, if it's in good shape, Spray a little more lube on the filler tube, to allow it to slide in the tank gasket easily.
make sure you don't pinch the vent line on the drivers side of the tank.
On 84/85 cars, remove the in-line frame rail mounted fuel pump. I hear there is a smaller fuel filter that will work, but the one I have experience with is a 93 ranger. While at the parts store, just look for the smallest filter with the same ends as the 93 ranger pump.

I think that will get you through it

I almost said that, man, strange........

**boostedbruiser** · 12-23-2005, 11:31 AM

Man i had a nice LONG description on how to do this and the power went out.

Anyways its cake follow directions above.

Don't forget to relieve the fuel pressure. Before i started i just unplugged the fuel relay(under driver seat) and tried to start the car. it takes a few seconds and saves you from having gas in your eyes.

The 93 ranger filter will work, currently using one. Need reroute lines a little to reach new filter. But there's still room for dual exhaust later on. I used some small muffler and had no clearance issues. just rerouted the lines to ENSURE no fires.

As a word of advice, I found a problem in the connector to my fuel pump. The connector on the top of the tank was broken in a way so that the pump didn't get power. Luckily i tried to turn the pump on before reinstalling it in the tank, to verify its operation. So my advice, once the pump is on the bracket. just plug it in the car harness and have someone turn the key on for you(don't forget relay). Listen for the pump to kick on for a breif second. you'll know if its working. once verified then reinstall in reverse order of disassembly.

Thanks Eric and boostedbruiser. I appreciate it. I will inspect everything this weekend, and determine what else I need to purchase. I don't want to have to do this again, 'cause I hate not having gas in the car=no driving! Painful.

Man i had a nice LONG description on how to do this and the power went out.

I feel your pain bro! UPS's are the bomb! Seriously tho, I appreciate you taking the time to write a long post. You too Eric, next year at the reunion I promise I won't make fun of your music selection! I'll post how it all works out at a later date. Feel free to post any personal experiences, but I feel confident I can do it.

To relieve fuel pressure in the system, just disconnect the vacuum line on the FPR, and, using a vacuum pump, draw approx. 25" of vacuum. This will allow the pressure to be relieved.

**boostedbruiser** · 12-23-2005, 11:52 AM

Not a problem. Let us know how it goes. Later on i will probably take some pics of my setup and mufflers to show the clearance and stuff. the muffler i have are half the size of a normal flowmasters(or equivelant) and tuck nicely in the empty are next to that filter.

Well fine then..... Do it his way see if i care. I didn't have a vacume pump handy.........

J/K Good idea.

**1fastII** · 12-23-2005, 11:52 PM

To relieve fuel pressure on mine, I just took the gas cap off when I started to work on the car. All the pressure was gone by the time I got to the lines. And I thought 86's didn't have an inline pump?

**SVOeric** · 12-24-2005, 01:25 AM

84/85 SVO's have a inline pump -- was there someone that said otherwise?

I'm like you, everytimg I've droped the tank, I put it off so long, by the time I do it, there's no pressure in it
