Hello Folks.
'79 Chev Van. 20 Series. 3/4 Ton. 350 V8 + 350 TH Tranny. Camper Van. Rochester 4 bbl carb ( fuel filter inside carb at fuel inlet ).
I've experienced symptoms of fuel starvation under load, several times, + replaced fuel filter( round cardboard thing, ~ o.5 in. dia. X ~ 1. in long ) located in carb. On inspection, old filter had rust dust inside. Latest filter only lasted ~ 500 Km. ( ~300 mi. ) before becoming plugged.
Van is camper + sits all winter; w/ full tank + fuel stabilizer.
?? Is removing + cleaning fuel tank inevitable to prevent rapid clogging of fuel filter ?
If so, any advice on procedure + cleaning material + difficulty of replacing fuel line ?
?? Will an inline additional fuel filter w/ replaceable cartridge just before carb be a satisfactory " work-around " of rust problem? ( I find re +re the existing filter to be no fun on side of road. )
?? Probably a stupid question, but here goes ( perhaps I'm in denial / looking for easy way out ) ... The previous time the filter got clogged I had no replacement on board so drove home ~ 500 mi. without filter, before replacing it, with no apparent deleterious effect. ?? Can I just remove filter + run without one ? ... or will carb die ? What else will suffer from contaminated fuel ?
Any advice gratefully rec'd. Please reply to NG. Thanks, -JS
