Why does a fuel filter, pre carb by about 12", end up empty after a couple of days go by from the last time you had the engine running? This is one of the reasons SF works better to geter going. Is a filter gone dry nothing unusual on these six bangers?
This may be a dumb question but is there supposed to be a one way check valve before the filter so it doesn't lose it's prime or is that only fuel injectied cars? If this is dumb then guys forgive me for my lack of carb knowlede!
I guess I should say this filter is betwix the pump and the carb. Near 'bout level with the bottom of the carb. The carb is a rebuilt thing from O'Really's.
Zig,ever check the fuel pump for bleeding off? Check the oil too bud,it may be wayyyy over full. You know, with gas and stuff.
Nope- the fuel pump is rebuilt also. Not that it couldn't be passing some gas... I did check the oil though. It's down a tad and just as oily looking as it can be. It's going somewhere. Great flow from the pump to the carb, so that's why I thought I'd pose the question. It's got me bumfuzzeled. I won't even be using this engine so I guess I shouldn't even bother. However- I JUST GOTTA' FIGURE THIS OUT! (with your help, of course! )
Not To Worry ! This is entirely normal . the fuel can bleed back down past a balky outlet valve in the fuel pump -or- it can simply evaporate from the carby and thence in the inlet line . This is part of why starting drill is so important . If your truck sits for a long time (week or more) between uses , simply add an electric fuel pump on the frame rail near the fuel tank and install a push button ~ hold the button down for 30 ~ 50 seconds to fill the carby , fire it up and you're off! .
That makes sense- Would this be another good reason to upgrade to 12 volt? This type of fuel pump is a common type? Thanks again, Nate!
Maybe ; If adjusting your starting drill doesn't take care of the problem ( I'm assuming it starts hard here) you could simply add a 6 volt pump , they're out there you just gotta seach , like from Kanter maybe . In any case , you'd -not- be wanting to use an electrical fuel pump in lieu of the mechanical one IMO so a regular ' high pressure ' (about 7 ~ 11 PSI) one from Facet would be fine . Be aware that if you decide to run an electronic fuel pump all the time , it must not exceed 3PSI ! . Of course , if it is starting & running fine and you're just bugged by the big air bubble in the fuel filter or by it draining back , take a chill pill & learn to live with it as it's entirely normal .
Naw, you gave me some great stuff to do to get my 228 to fire up Nate- This is just one of those things that bugs me- I'm sure the non-start has more to do with adjustment then a pretty looking half full/half empty/completely empty fuel filter. Chill pills are a thing of the past. These daze it's more about those nice red grapes than anything else.
