Fuel pump failed

[RichardT10829]

Despite inline filters either side of the pump it would pick up the slightest bit of muck and it would block.

I also found with the pump being mounted in the engine bay, on long hot runs the pump would vapour lock, or would appear to vapour lock.

I ran mine mounted to the lower plate on the rear of the hull and had an adjustable "King" filter and reg... The stromberg 97 carb I used only liked a maximum delivery pressure of 2.5psi and the facet was capable of more than this.

I ran an inline fuel pressure gauge too.

Facet don't do a 6v pump....I am running 12v system on the engine, I have a regulator box and some magic trickery hidden away so all my 6v gauges still work as they should.
A pal re flashed my generator to charge for 12V (it was a three brush genny with one brush removed)

Hi Guys

One thing I've noted is that fuel pumps mechanical or electrical don't seem to like standing empty and dry once they have had ethanol gas through them. They seem to loose the ability to self prime. Some times once you get fuel back into them they will start working again.

Noticed this problem when setting engines up on the test stand that once the engines were ready to install if they stood with no fuel in the fuel lines and pump(s) while waiting to be installed in the trucks the pumps would not work when installed. In that case the solution seems fairly simple when I finish running the engines in on the test stand make sure the gas line and pumps are left full of gas and plug the end. On the test stand I use an electric pump and when done with test runs with fuel in line just loop the outlet back to the inlet side. Have also tried squirting some oil into the pump but the jury is still out on does this work.

Cheers Phil

It was the same in the pre-ethanol days. I bought a few of the best Jeeps for the least amount of money back in the day when the crown assets guys couldn't get them to go. Once they were in my posession, a squrt of fuel into the pump to wet the checkvalves did the trick.
